# @PLUGIN@ - /checks.pending/ REST API

This page describes the pending-checks-related REST endpoints that are
added by the @PLUGIN@ plugin.

Please also take note of the general information on the
[REST API](../../../Documentation/rest-api.html).

## <a id="pending-checks-endpoints"> Pending Checks Endpoints

### <a id="get-checker"> List Pending Checks
_'GET /checks.pending/'_

Lists pending checks for a checker or for all checkers of a scheme.

Checks are pending if they are in a non-final state and the external
checker system intends to post further updates on them.

By default this REST endpoint only returns checks that are in state
`NOT_STARTED` but callers may specify the states that they are
interested in (see [state](#state-param) request parameter).

Request parameters:

* <a id="checker-param"> `checker`: the UUID of the checker for which
  pending checks should be listed (optional, if not specified `scheme`
  must be set)
* <a id="scheme-param"> `scheme`: the scheme of the checkers for which
  pending checks should be listed (optional, if not specified `checker`
  must be set)
* <a id="state-param"> `state`: state that should be considered as
  pending (optional, by default the state `NOT_STARTED` is assumed,
  this option may be specified multiple times to request checks
  matching any of several states)

Note that only users with the [Administrate
Checkers](access-control.md#capability_administrateCheckers) global capability
are permitted to list pending checks.
