=== Create Change
--
'POST /changes/'
--

The change input link:#change-input[ChangeInput] entity must be
provided in the request body. It is not allowed to create changes
under `refs/tags/` or Gerrit internal ref namespaces such as
`refs/changes/`, `refs/meta/external-ids/`, and `refs/users/`. The
request would fail with `400 Bad Request` in this case.

To create a change the calling user must be allowed to
link:access-control.html#category_push_review[upload to code review].

[[list-changes]]
=== Query Changes
--
'GET /changes/'
--

Queries changes visible to the caller. The
link:user-search.html#_search_operators[query string] must be provided
by the `q` parameter. The `n` parameter can be used to limit the
returned results. The `no-limit` parameter can be used remove the default
limit on queries and return all results (does not apply to anonymous requests).
This might not be supported by all index backends.

As result a list of link:#change-info[ChangeInfo] entries is returned.
The change output is sorted by the last update time, most recently
updated to oldest updated.

----

If the number of changes matching the query exceeds either the internal
limit or a supplied `n` query parameter, the last change object has a
`_more_changes: true` JSON field set.

The `S` or `start` query parameter can be supplied to skip a number
of changes from the list.

Administrators can use the `skip-visibility` query parameter to skip visibility filtering.
This can be used to ensure that no changes are missed e.g. when querying for changes which
need to be reindexed. Without this parameter query results the user has no permission to read
are filtered out. REST requests with the skip-visibility option are rejected when the current
user doesn't have the ADMINISTRATE_SERVER capability.

The `allow-incomplete-results` query parameter can be used. This is a boolean
parameter that can optionally be set to true. If set, the server can tolerate
handling faulty records when parsed from the change index, for example if a
field contained a value of a wrong format. For faulty records, the server
will return a canonical empty record where only the fields {project, branch,
change_id, _number, owner} are set and the subject will be set to
"\*\**ERROR***". All other fields will be empty.
Note that the handling of this parameter is up to the index implementation.

Clients are allowed to specify more than one query by setting the `q`
parameter multiple times. In this case the result is an array of
arrays, one per query in the same order the queries were given in.

[[query-options]]
Additional fields can be obtained by adding `o` parameters, each
option requires more database lookups and slows down the query
response time to the client so they are generally disabled by
default. Optional fields are:

[[labels]]
--
* `LABELS`: Includes the `labels` field which contains all information about
labels and approvers that have granted (or rejected) that label. Does not
include the `permitted_voting_range` attribute with the list of
link:#approval-info[ApprovalInfo] of the `all` attribute.
--

[[detailed-labels]]
--
* `DETAILED_LABELS`: Includes the `labels` field which contains all information
about labels and approvers that have granted (or rejected) that label, including
the `permitted_voting_range` attribute with the list of
link:#approval-info[ApprovalInfo] of the `all` attribute.
--

[[submit-requirements]]
--
* `SUBMIT_REQUIREMENTS`: detailed result of the evaluated submit requirements
  for this change.
--

[[current-revision]]
--
* `CURRENT_REVISION`: describe the current revision (patch set)
  of the change, including the commit SHA-1 and URLs to fetch from.
--

[[all-revisions]]
--
* `ALL_REVISIONS`: describe all revisions, not just current.
--

[[download-commands]]
--
* `DOWNLOAD_COMMANDS`: include the `commands` field in the
  link:#fetch-info[FetchInfo] for revisions. Only valid when the
  `CURRENT_REVISION` or `ALL_REVISIONS` option is selected.
--

[[current-commit]]
--
* `CURRENT_COMMIT`: parse and output all header fields from the
  commit object, including message. Only valid when the
  `CURRENT_REVISION` or `ALL_REVISIONS` option is selected.
--

[[all-commits]]
--
* `ALL_COMMITS`: parse and output all header fields from the
  output revisions. If only `CURRENT_REVISION` was requested
  then only the current revision's commit data will be output.
--

[[current-files]]
--
* `CURRENT_FILES`: list files modified by the commit and magic files,
  including basic line counts inserted/deleted per file. Only valid
  when the `CURRENT_REVISION` or `ALL_REVISIONS` option is selected.
--

[[all-files]]
--
* `ALL_FILES`: list files modified by the commit and magic files,
  including basic line counts inserted/deleted per file. If only the
  `CURRENT_REVISION` was requested then only that commit's modified
  files will be output.
--

[[detailed-accounts]]
--
* `DETAILED_ACCOUNTS`: include `_account_id`, `email` and `username`
  fields when referencing accounts.
--

[[reviewer-updates]]
--
* `REVIEWER_UPDATES`: include updates to reviewers set as

--

[[change-actions]]
--
* `CHANGE_ACTIONS`: include information on available
  change actions for the change. Ignored if the caller
  is not authenticated.
--

[[reviewed]]
--
* `REVIEWED`: include the `reviewed` field if all of the following are
  true:
  - the change is open
  - the caller is authenticated
  - the caller has commented on the change more recently than the last update
    from the change owner, i.e. this change would show up in the results of
    link:user-search.html#reviewedby[reviewedby:self].
--
[[skip_diffstat]]
--
* `SKIP_DIFFSTAT`: skip the 'insertions' and 'deletions' field in link:#change-info[ChangeInfo].
 For large trees, their computation may be expensive.
--

[[submittable]]
--
* `SUBMITTABLE`: include the `submittable` field in link:#change-info[ChangeInfo],
  which can be used to tell if the change is reviewed and ready for submit.
--

[[web-links]]

--
* `CUSTOM_KEYED_VALUES`: include the custom key-value map
--

[[star]]
--
* `STAR`: include the `starred` field in
   link:#change-info[ChangeInfo], which indicates if the change is starred
   by the current user or not.
--

[[parents-data]]
--
* `PARENTS`: include the `parents_data` field in
   link:#revision-info[RevisionInfo], which provides information of whether the
   parent commit of this revision, e.g. if it's merged in the target branch
   and whether it points to a patch-set of another change.

Historical state of the change can be retrieved by specifying the
`meta=SHA-1` parameter. This will use a historical NoteDb snapshot to
populate ChangeInfo. If the SHA-1 is not reachable as a NoteDb state,
status code 412 is returned.

[[get-meta-diff]]
=== Get Meta Diff
--
'GET /changes/link:#change-id[\{change-id\}]/meta_diff?old=SHA-1&meta=SHA-1'
--

Retrieves the difference between two historical states of a change
by specifying the `old=SHA-1` and the `meta=SHA-1` parameters.

If the `old` parameter is not provided, the parent of the `meta`
SHA-1 is used. If the `meta` parameter is not provided, the current
state of the change is used. If neither are provided, the
difference between the current state of the change and its previous
state is returned.

Additional fields can be obtained by adding `o` parameters, analogous
to link:#get-change[Get Change], and the same concerns for Get Change hold for
this endpoint too. Fields are described in link:#list-changes[Query Changes].

----

As a response, two link:#change-info[ChangeInfo] entities are returned
that describe information added and removed from the `old` change state, and
the two link:#change-info[ChangeInfo] entities that generated the diff are
returned. Only fields that differ between the change's two states are returned.

state, the status code 412 is returned. If the SHA-1 for `old`
is not reachable, the difference between the change at state
`meta` and an empty change is returned.

link:#reviewer-updates[reviewer updates], and link:#messages[messages].

Additional fields can be obtained by adding `o` parameters, each
option requires more database lookups and slows down the query
response time to the client so they are generally disabled by
default. Fields are described in link:#list-changes[Query Changes].

Update an existing change by using a
link:#merge-patch-set-input[MergePatchSetInput] entity.

Gerrit will create a merge commit based on the information of
MergePatchSetInput and add a new patch set to the change corresponding
to the new merge commit.

If one of the secondary emails associated with the user performing the operation was used as the
committer email in the current patch set, the same email will be used as the committer email in the
new patch set; otherwise, the user's preferred email will be used.

[[rebase-change]]
=== Rebase Change
--
'POST /changes/link:#change-id[\{change-id\}]/rebase'
--

Rebases a change.

For merge commits always the first parent is rebased. This means the new base becomes the first
parent of the rebased merge commit while the second parent stays intact.

If one of the secondary emails associated with the user performing the operation was used as the
committer email in the current patch set, the same email will be used as the committer email in the
new patch set; otherwise, the user's preferred email will be used.

Optionally, the parent revision can be changed to another patch set through the
link:#rebase-input[RebaseInput] entity.

If the change cannot be rebased, e.g. due to conflicts, the response is
"`409 Conflict`" and the error message is contained in the response
body.

.Response
----
  HTTP/1.1 409 Conflict
  Content-Disposition: attachment
  Content-Type: text/plain; charset=UTF-8

  The change could not be rebased due to a path conflict during merge.
----

Rebasing a change is allowed for the change owner, users with the
link:access-control.html#category_rebase[Rebase] permission and users
with the link:access-control.html#category_submit[Submit] permission.

In addition, the rebaser or the original uploader, if rebasing is done
on behalf of the uploader (see `rebase_on_behalf_of_uploader` option in
link:#rebase-input[RebaseInput]), needs to have all permissions that
are required to create the new patch set:

* the link:access-control.html#category_push[Push] permission
* the link:access-control.html#category_add_patch_set[Add Patch Set]
  permission (only if the user is not the change owner)
* the link:access-control.html#category_forge_author[Forge Author]
  permission (only if the commit author is forged)
* the link:access-control.html#category_forge_server[Forge Server]
  permission (only if the commit author is the server identity)

The same permissions were required for the upload of the original patch
set. This means if the rebase is done on behalf of the uploader these
permission checks should just pass, unless the uploader lost
permissions after the upload of the original patch set. In this case
rebasing on behalf of the uploader is not possible and a normal rebase
(on behalf of the rebaser) must be done, which means that the rebaser
becomes the uploader and takes over the change. If self approvals are
disallowed, this means that the rebaser can no longer approve the
change (as approvals of the uploader are ignored).

[[rebase-chain]]
=== Rebase Chain
--
'POST /changes/link:#change-id[\{change-id\}]/rebase:chain'
--

Rebases an ancestry chain of changes.

If one of the secondary emails associated with the user performing the operation was used as the
committer email in the current patch set, the same email will be used as the committer email in the
new patch set; otherwise, the user's preferred email will be used.

The operated change is treated as the chain tip. All unsubmitted ancestors are rebased.

Requires a linear ancestry relation (single parenting throughout the chain).

Optionally, the parent revision (of the oldest ancestor to be rebased) can be changed to another
change, revision or branch through the link:#rebase-input[RebaseInput] entity.

Providing a `committer_email` through the link:#rebase-input[RebaseInput] entity is not supported
when rebasing a chain.

If the chain is outdated, i.e., there's a change that depends on an old revision of its parent, the
result is the same as individually rebasing all outdated changes on top of their parent's latest
revision before running the rebase chain action.

[[revert-submission]]
=== Revert Submission
--
'POST /changes/link:#change-id[\{change-id\}]/revert_submission'
--

Creates open revert changes for all of the changes of a certain submission.

The subject of each revert change will be 'Revert "<subject-of-reverted-change"'.
If the subject is above 60 characters, the subject will be cut to 56 characters
with "..." in the end. However, whenever reverting the submission of a revert
submission, the subject will be shortened from
'Revert "Revert "<subject-of-reverted-change""' to
'Revert^2 "<subject-of-reverted-change"'. Also, for every future revert submission,
the only difference in the subject will be the number of the revert (instead of
Revert^2 the subject will change to Revert^3 and so on).
There are no guarantees about the subjects if the users change the default subjects.

Details for the revert can be specified in the request body inside a link:#revert-input[
RevertInput] The topic of all created revert changes will be
`revert-{submission_id}-{random_string_of_size_10}`.

The changes will not be rebased on onto the destination branch so the users may still
have to manually rebase them to resolve conflicts and make them submittable.

However, the changes that have the same project and branch will be rebased on top
of each other. E.g, the first revert change will have the original change as a
parent, and the second revert change will have the first revert change as a
parent.

There is one special case that involves merge commits; if a user has multiple
changes in the same project and branch, but not in the same change series, those
changes can still get submitted together if they have the same topic and
link:config-gerrit.html#change.submitWholeTopic[`change.submitWholeTopic`] in
gerrit.config is set to true. In the case, Gerrit may create merge commits on
submit (depending on the link:config-project-config.html#submit-type[submit types]
of the project).
The first parent for the reverts will be the most recent merge commit that was
created by Gerrit to merge the different change series into the target branch.

=== Submit Change
--
'POST /changes/link:#change-id[\{change-id\}]/submit'
--

Submits a change.

If the submission results in a new patch set (due to a rebase or cherry-pick merge method), the
committer email will remain the same as the one used in the previous commit, provided that one of
the secondary emails associated with the user performing the operation was used as the committer
email in the previous commit. Otherwise, the user's preferred email will be used.

The request body only needs to include a link:#submit-input[
SubmitInput] entity if submitting on behalf of another user.

Submitting a change also removes all users from the link:user-attention-set.html[attention set].

configuration is set to true.
2. All dependent changes.
3. The closure of the above (e.g if a dependent change has a topic, all changes
of *that* topic will also be submitted).

[[add-reviewer]]
=== Add Reviewer
--
'POST /changes/link:#change-id[\{change-id\}]/reviewers'
--

Adds one user or all members of one group as reviewer to the change.

The reviewer to be added to the change must be provided in the request
body as a link:#reviewer-input[ReviewerInput] entity.

Users can be moved from reviewer to CC and vice versa. This means if a
user is added as CC that is already a reviewer on the change, the
reviewer state of that user is updated to CC. If a user that is already
a CC on the change is added as reviewer, the reviewer state of that
user is updated to reviewer.

Adding a new reviewer also adds that reviewer to the attention set, unless
the change is work in progress.
Also, moving a reviewer to CC removes that user from the attention set.

If a group is specified, adding the group members as reviewers is an
atomic operation. This means if an error is returned, none of the
members are added as reviewer.

If a group with many members is added as reviewer a confirmation may be
required.

If a group is added as CC and members of this group are already
reviewers on the change, these members stay reviewers on the change
(they are not downgraded to CC). However if a group is added as
reviewer, all group members become reviewer of the change, even if they
have been added as CC before.

If link:config-project-config.html#reviewer.enableByEmail[reviewer.enableByEmail] is set
for the project, reviewers and CCs are not required to have a Gerrit account. If you POST
an email address of a reviewer or CC then, they will be added to the change even if they
don't have a Gerrit account.

If this option is disabled, the request would fail with `400 Bad Request` if the email
address can't be resolved to an active Gerrit account.

Note that the name is optional so both "un.registered@reviewer.com" and
"John Doe <un.registered@reviewer.com>" are valid inputs.

Reviewers without Gerrit accounts can only be added on changes visible to anonymous users.

[[get-related-changes]]
=== Get Related Changes
--
'GET /changes/link:#change-id[\{change-id\}]/revisions/link:#revision-id[\{revision-id\}]/related'

Retrieves related changes of a revision.  Related changes are changes that either
depend on, or are dependencies of the revision.

Additional fields can be obtained by adding `o` parameters. Since these may slow
down processing they are disabled by default. Currently a single parameter is
supported:

[[get-related-changes-submittable]]

[[set-review]]
=== Set Review
--
'POST /changes/link:#change-id[\{change-id\}]/revisions/link:#revision-id[\{revision-id\}]/review'
--

Sets a review on a revision, optionally also publishing draft comments, setting
labels, adding reviewers or CCs, and modifying the work in progress property.

The review must be provided in the request body as a
link:#review-input[ReviewInput] entity.

If the labels are set, the user sending the request will automatically be
added as a reviewer, otherwise (if they only commented) they are added to
the CC list.

Posting a review usually updates the link:user-attention-set.html[attention
set].

A review cannot be set on a change edit. Trying to post a review for a
change edit fails with `409 Conflict`.

Here is an example of using this method to set labels:

          },
          "message": "Incorrect indentation"
        }
      ]
    }
  }
----

As response a link:#review-result[ReviewResult] entity is returned that
describes the applied labels and any added reviewers (e.g. yourself,
if you set a label but weren't previously a reviewer on this CL).

to a change simultaneously with a review:

[[set-review-notifications]]
.Notifications

An email will be sent using the "comment" template.

If the top-level notify property is null or not set, then notification behavior
depends on whether the change is WIP, whether it has started review, and whether
the tag property is null.

NOTE: If adding reviewers, the notify property of each ReviewerInput is *ignored*.
Use the notify property of the top-level link:#review-input[ReviewInput] instead.

For the purposes of this table, *everyone* means *owner, reviewers, CCs, stars, and ALL_COMMENTS
watchers*.

[options="header",cols="2,1,1,2,2"]

If reviewers are added, then a second email will be sent using the "newchange"

link:#add-reviewer[Add Reviewer].

----

Adding query parameter `zip` (for example `/changes/.../patch?zip`)
returns the patch as a single file inside of a ZIP archive. Clients
can expand the ZIP to obtain the plain text patch, avoiding the
need for a base64 decoding step. This option implies `download`.

Query parameter `download` (e.g. `/changes/.../patch?download`)
will suggest the browser save the patch as `commitsha1.diff.base64`,
for later processing by command line tools.

If the `path` parameter is set, the returned content is a diff of the single
file that the path refers to.

Deletes a published comment of a revision. Instead of deleting the
whole comment, this endpoint just replaces the comment's message
with a new message, which contains the name of the user who deletes
the comment and the reason why it's deleted.

This endpoint also marks the comment as resolved since deleted comments are not
actionable.

Note that only users with the
link:access-control.html#capability_administrateServer[Administrate Server]
global capability are permitted to delete a comment.

Deletion reason can be provided in the request body as a
link:#delete-comment-input[DeleteCommentInput] entity.
Historically, this method allowed a body in the DELETE, but that behavior is
link:https://www.gerritcodereview.com/releases/2.16.md[deprecated,role=external,window=_blank].

[[list-ported-comments]]
=== List Ported Comments
--
'GET /changes/link:#change-id[\{change-id\}]/revisions/link:#revision-id[\{revision-id\}]/ported_comments'
--

Ports comments of other revisions to the requested revision.

Only comments added on earlier patchsets are ported. That set of comments is filtered even further
due to some additional rules. Callers of this endpoint shouldn't rely on the exact logic of which
comments are ported as that logic might change in the future. Instead, callers must be able to
handle any smaller/larger set of comments returned by this endpoint.

Typically, a comment thread is returned fully or excluded fully. However, draft comments and
robot comments are ignored and not returned via this endpoint. Hence, it's possible to get ported
comments from this endpoint which are a reply to a non-ported robot comment. Callers must be
able to deal with this situation.

The returned comments are organized in a map of file path to link:#comment-info[CommentInfo] entries
in the same fashion as for the link:#list-comments[List Revision Comments] endpoint.
The map is filled with the original comment attributes except for these attributes: `path`, `line`,
and `range` point to the computed position in the target revision. If the exactly correct position
can't be determined, those fields will be filled with the next best position. That can also mean
not filling the `line` or `range` attribute anymore and thus converting the comment to a file
comment (or even moving the comment to a different file or the patchset level). Callers of this
endpoint must be able to deal with this and not rely on the original comment position.

It's possible that this endpoint returns different link:#comment-info[CommentInfo] entries with
the same comment UUID. This is not a bug but a feature. If a comment appears on a file which Gerrit
recognizes as copied between patchsets, the ported version of this comment consists of two ported
instances having the same UUID but different `file`/`line`/`range` positions. Callers must be able
to handle this situation.

Repeated calls of this endpoint might produce different results. Internal errors during the
position computation are mapped to fallback locations for affected comments. Those errors might
have vanished on later calls, upon which this endpoint returns the actually mapped position. In
addition, comments can be deleted and draft comments can be published, upon which the set of ported
comments may change.

=== List Ported Drafts
--
'GET /changes/link:#change-id[\{change-id\}]/revisions/link:#revision-id[\{revision-id\}]/ported_drafts'
--

Ports draft comments of other revisions to the requested revision.

This endpoint behaves similarly to the link:#list-ported-comments[List Ported Comments] endpoint.
With this endpoint, only draft comments of the calling user are ported, though. If a draft comment
is a reply to a published comment, only the ported draft comment is returned.

Depending on the filtering rules, it's possible that this endpoint returns a draft comment which is
a reply to a comment thread which is not returned by the
link:#list-ported-comments[List Ported Comments] endpoint. That's intended behavior. Callers must be
able to handle this situation. The same holds for drafts which are a reply to a robot comment.

Different than the link:#list-ported-comments[List Ported Comments] endpoint, the `author` of the
returned comments is not filled for this endpoint as only comments of the calling user are returned.

This endpoint requires authentication.

=== Apply Stored Fix
--
'POST /changes/<<change-id,\{change-id\}>>/revisions/<<revision-id,\{revision-id\}>>/fixes/<<fix-id,\{fix-id\}>>/apply'
--

Applies a suggested fix by creating a change edit which includes the
modifications indicated by the fix suggestion. If a change edit already exists,
it will be updated accordingly. A fix can only be applied if no change edit
exists and the fix refers to the current patch set, or the fix refers to the
patch set on which the change edit is based.

If one of the secondary emails associated with the user performing the operation was used as the
committer email in the current patch set, the same email will be used as the committer email in the
new change edit commit; otherwise, the user's preferred email will be used.

The request parameter `reviewed` changes the response to return a list
of the paths the caller has marked as reviewed.  Clients that also
need the FileInfo should make two requests.

The request parameter `q` changes the response to return a list
of all files (modified or unmodified) that contain that substring
in the path name. This is useful to implement suggestion services
finding a file by partial name.  Clients that also need the FileInfo
should make two requests.

For merge commits only, the integer-valued request parameter `parent`
changes the response to return a map of the files which are different
in this commit compared to the given parent commit. The value is the
1-based index of the parent's position in the commit object,
with the first parent always belonging to the target branch. If not
specified, the response contains a map of the files different in the
auto merge result.

The request parameter `base` changes the response to return a map of the
files which are different in this commit compared to the given revision. The
revision must correspond to a patch set in the change.

The `reviewed`, `q`, `parent`, and `base` options are mutually exclusive.
That is, only one of them may be used at a time.

=== Get Content
--
'GET /changes/link:#change-id[\{change-id\}]/revisions/link:#revision-id[\{revision-id\}]/files/link:#file-id[\{file-id\}]/content'
--

Gets the content of a file from a certain revision.

The optional, integer-valued `parent` parameter can be specified to request
the named file from a parent commit of the specified revision. The value is
the 1-based index of the parent's position in the commit object. If the
parameter is omitted or the value is non-positive, the patch set is referenced.

.Request

----

The content is returned as base64 encoded string.  The HTTP response
Content-Type is always `text/plain`, reflecting the base64 wrapping.
A Gerrit-specific `X-FYI-Content-Type` header is returned describing
the server detected content type of the file.

If only the content type is required, callers should use HEAD to
avoid downloading the encoded file contents.

Alternatively, if the only value of the Accept request header is
`application/json` the content is returned as JSON string and
`X-FYI-Content-Encoding` is set to `json`.

[[get-safe-content]]
=== Download Content
--
'GET /changes/link:#change-id[\{change-id\}]/revisions/link:#revision-id[\{revision-id\}]/files/link:#file-id[\{file-id\}]/download'
--

Downloads the content of a file from a certain revision, in a safe format
that poses no risk for inadvertent execution of untrusted code.

If the content type is defined as safe, the binary file content is returned
verbatim. If the content type is not safe, the file is stored inside a ZIP
file, containing a single entry with a random, unpredictable name having the
same base and suffix as the true filename. The ZIP file is returned in
verbatim binary form.

See link:config-gerrit.html#mimetype.name.safe[Gerrit config documentation]
for information about safe file type configuration.

The HTTP resource Content-Type is dependent on the file type: the
applicable type for safe files, or "application/zip" for unsafe files.

The optional, integer-valued `parent` parameter can be specified to request
the named file from a parent commit of the specified revision. The value is
the 1-based index of the parent's position in the commit object. If the
parameter is omitted or the value non-positive, the patch set is referenced.

Filenames are decorated with a suffix of `_new` for the current patch,
`_old` for the only parent, or `_oldN` for the Nth parent of many.

As response, a map of link:#diff-info[DiffInfo] is returned that describes the diffs.

Each link:#diff-info[DiffInfo] is the differences between the patch set indicated by revision-id
and a virtual patch set with the applied fix. No content on the server will be modified as part of this request.

[[cherry-pick]]
=== Cherry Pick Revision
--
'POST /changes/link:#change-id[\{change-id\}]/revisions/link:#revision-id[\{revision-id\}]/cherrypick'
--

Cherry picks a revision to a destination branch.

If one of the secondary emails associated with the user performing the operation was used as the
committer email in the original revision, the same email will be used as the committer email
in the new patch set; otherwise, the user's preferred email will be used.

To cherry pick a commit with no change-id associated with it, see
link:rest-api-projects.html#cherry-pick-commit[CherryPickCommit].

The commit message and destination branch must be provided in the request body inside a
link:#cherrypick-input[CherryPickInput] entity.  If the commit message
does not specify a Change-Id, a new one is picked for the destination change.

When cherry-picking a change into a branch that already contains the Change-Id
that we want to cherry-pick, the cherry-pick will create a new patch-set on the
destination's branch's appropriate Change-Id. If the change is closed on the
destination branch, the cherry-pick will fail.

[[ids]]
== IDs

[[account-id]]
=== link:rest-api-accounts.html#account-id[\{account-id\}]
--
--

[[change-id]]
=== \{change-id\}
Identifier that uniquely identifies one change. It contains the URL-encoded
project name as well as the change number: "<project>~<changeNumber>"

==== Alternative identifiers
Gerrit also supports an array of other change identifiers.

[NOTE]
Even though these identifiers will work in the majority of cases it is highly
recommended to use "<project>~<changeNumber>" whenever possible.
Since these identifiers require additional lookups from index and caches, to
be translated to the "<project>~<changeNumber>" identifier, they
may result in both false-positives and false-negatives.
Furthermore the additional lookup mean that they come with a performance penalty.

* an ID of the change in the format "<project>\~<branch>~<Change-Id>",
  where for the branch the `refs/heads/` prefix can be omitted
  ("myProject\~master~I8473b95934b5732ac55d26311a706c9c2bde9940")
* a Change-Id if it uniquely identifies one change
  ("I8473b95934b5732ac55d26311a706c9c2bde9940")
* a change number if it uniquely identifies one change ("4247")

[[change-message-id]]
=== \{change-message-id\}
ID of a change message returned in a link:#change-message-info[ChangeMessageInfo].

[[comment-id]]
=== \{comment-id\}
UUID of a published comment.

[[draft-id]]
=== \{draft-id\}
UUID of a draft comment.

[[label-id]]
=== \{label-id\}
The name of the label.

[[file-id]]
=== \{file-id\}
The path of the file.

The following magic paths are supported:

* `/COMMIT_MSG`:
+
The commit message and headers with the parent commit(s), the author
information and the committer information.

* `/MERGE_LIST` (for merge commits only):
+
The list of commits that are being integrated into the destination
branch by submitting the merge commit.

* `/PATCHSET_LEVEL`:
+
This file path is used exclusively for posting and indicating
patchset-level comments, thus not relevant for other use-cases.

[[fix-id]]
=== \{fix-id\}
UUID of a suggested fix.

[[revision-id]]
=== \{revision-id\}
Identifier that uniquely identifies one revision of a change.

This can be:

* the literal `current` to name the current patch set/revision
* a commit ID ("674ac754f91e64a0efb8087e59a176484bd534d1")
* an abbreviated commit ID that uniquely identifies one revision of the
  change ("674ac754"), at least 4 digits are required
* a numeric patch number ("1" for first patch set of the change)
* "0" or the literal `edit` for a change edit

[[json-entities]]
== JSON Entities

[[abandon-input]]
=== AbandonInput
The `AbandonInput` entity contains information for abandoning a change.

[options="header",cols="1,^1,5"]
|=============================
|Field Name      ||Description
|`message`       |optional|
Message to be added as review comment to the change when abandoning the
change.
|`notify`        |optional|
Notify handling that defines to whom email notifications should be sent after
the change is abandoned. +
Allowed values are `NONE`, `OWNER`, `OWNER_REVIEWERS` and `ALL`. +
If not set, the default is `ALL`.
|`notify_details`|optional|
Additional information about whom to notify about the update as a map
of link:user-notify.html#recipient-types[recipient type] to
link:#notify-info[NotifyInfo] entity.
|=============================

[[action-info]]
=== ActionInfo
The `ActionInfo` entity describes a REST API call the client can
make to manipulate a resource. These are frequently implemented by
plugins and may be discovered at runtime.

[options="header",cols="1,^1,5"]
|====================================
|Field Name             ||Description
|`method`               |optional|
HTTP method to use with the action. Most actions use `POST`, `PUT`
or `DELETE` to cause state changes.
|`label`                |optional|
Short title to display to a user describing the action. In the
Gerrit web interface the label is used as the text on the button
presented in the UI.
|`title`                |optional|
Longer text to display describing the action. In a web UI this
should be the title attribute of the element, displaying when
the user hovers the mouse.
|`enabled`              |optional|
If true the action is permitted at this time and the caller is
likely allowed to execute it. This may change if state is updated
at the server or permissions are modified. Not present if false.
|`enabled_options`      |optional|
Optional list of enabled options. +
See the list of suppported options link:#action-options[below].
