Gerrit Code Review - REST API
=============================

Gerrit Code Review comes with a REST like API available over HTTP.
The API is suitable for automated tools to build upon, as well as
supporting some ad-hoc scripting use cases.

Protocol Details
----------------

Authentication
~~~~~~~~~~~~~~
By default all REST endpoints assume anonymous access and filter
results to correspond to what anonymous users can read (which may
be nothing at all).

Users (and programs) may authenticate using HTTP authentication by
supplying the HTTP password from the user's account settings page.
Gerrit by default uses HTTP digest authentication. To authenticate,
prefix the endpoint URL with `/a/`. For example to authenticate to
`/projects/` request URL `/a/projects/`.

Output Format
~~~~~~~~~~~~~
Most APIs return text format by default. JSON can be requested
by setting the `Accept` HTTP request header to include
`application/json`, for example:

----
  GET /projects/ HTTP/1.0
  Accept: application/json
----

JSON responses are encoded using UTF-8 and use content type
`application/json`. The JSON response body starts with a magic prefix
line that must be stripped before feeding the rest of the response
body to a JSON parser:

----
  )]}'
  [ ... valid JSON ... ]
----

The default JSON format is `JSON_COMPACT`, which skips unnecessary
whitespace. This is not the easiest format for a human to read. Many
examples in this documentation use `format=JSON` as a query parameter
to obtain pretty formatting in the response. Producing (and parsing)
the compact format is more efficient, so most tools should prefer the
default compact format.

Responses will be gzip compressed by the server if the HTTP
`Accept-Encoding` request header is set to `gzip`. This may
save on network transfer time for larger responses.

Endpoints
---------

[[accounts_self_capabilities]]
/accounts/self/capabilities (Account Capabilities)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Returns the global capabilities (such as createProject or
createGroup) that are enabled for the calling user. This can be used
by UI tools to discover if administrative features are available
to the caller, so they can hide (or show) relevant UI actions.

----
  GET /accounts/self/capabilities?format=JSON HTTP/1.0

  )]}'
  {
    "queryLimit": {
      "min": 0,
      "max": 500
    }
  }
----

Administrator that has authenticated with digest authentication:
----
  GET /a/accounts/self/capabilities?format=JSON HTTP/1.0
  Authorization: Digest username="admin", realm="Gerrit Code Review", nonce="...

  )]}'
  {
    "administrateServer": true,
    "queryLimit": {
      "min": 0,
      "max": 500
    },
    "createAccount": true,
    "createGroup": true,
    "createProject": true,
    "killTask": true,
    "viewCaches": true,
    "flushCaches": true,
    "viewConnections": true,
    "viewQueue": true,
    "startReplication": true
  }
----

[[projects]]
/projects/ (List Projects)
~~~~~~~~~~~~~~~~~~~~~~~~~~
Lists the projects accessible by the caller. This is the same as
using the link:cmd-ls-projects.html[ls-projects] command over SSH,
and accepts the same options as query parameters.

----
  GET /projects/?format=JSON&d HTTP/1.0

  HTTP/1.1 200 OK
  Content-Disposition: attachment
  Content-Type: application/json;charset=UTF-8
   
  )]}'
  {
    "external/bison": {
      "description": "GNU parser generator"
    },
    "external/gcc": {},
    "external/openssl": {
      "description": "encryption\ncrypto routines"
    },
    "test": {
      "description": "\u003chtml\u003e is escaped"
    }
