Merge requests API

Every API call to merge requests must be authenticated.

CAUTION: Deprecation:

reference attribute in response is deprecated in favour of references. Introduced GitLab 12.6

NOTE: Note:

references.relative is relative to the group / project that the merge request is being requested. When merge request is fetched from its project relative format would be the same as short format and when requested across groups / projects it is expected to be the same as full format.

List merge requests

Introduced in GitLab 9.5.

Get all merge requests the authenticated user has access to. By default it returns only merge requests created by the current user. To get all merge requests, use parameter scope=all.

The state parameter can be used to get only merge requests with a given state (opened, closed, locked, or merged) or all of them (all). It should be noted that when searching by locked it will mostly return no results as it is a short-lived, transitional state. The pagination parameters page and per_page can be used to restrict the list of merge requests.

GET /merge_requests
GET /merge_requests?state=opened
GET /merge_requests?state=all
GET /merge_requests?milestone=release
GET /merge_requests?labels=bug,reproduced
GET /merge_requests?author_id=5
GET /merge_requests?author_username=gitlab-bot
GET /merge_requests?my_reaction_emoji=star
GET /merge_requests?scope=assigned_to_me
GET /merge_requests?search=foo&in=title

deployed_after	datetime	no	Return merge requests deployed after the given date/time. Expected in ISO 8601 format (2019-03-15T08:00:00Z)

NOTE: Note: Starting in GitLab 13.0, listing merge requests may not proactively update the merge_status field (which also affects the has_conflicts field), as this can be an expensive operation. If you are interested in the value of these fields from this endpoint, set the with_merge_status_recheck parameter to true in the query.

NOTE: Note: Starting in GitLab 12.8, the mergeability (merge_status) of each merge request will be checked asynchronously when a request is made to this endpoint. Poll this API endpoint to get updated status. This affects the has_conflicts property as it is dependent on the merge_status. It'll return false unless merge_status is cannot_be_merged.

List project merge requests

Get all merge requests for this project. The state parameter can be used to get only merge requests with a given state (opened, closed, locked, or merged) or all of them (all). The pagination parameters page and per_page can be used to restrict the list of merge requests.

GET /projects/:id/merge_requests

GET /projects/:id/merge_requests?labels=bug,reproduced
GET /projects/:id/merge_requests?my_reaction_emoji=star

project_id represents the ID of the project where the MR resides. project_id will always equal target_project_id.

In the case of a merge request from the same project, source_project_id, target_project_id and project_id will be the same. In the case of a merge request from a fork, target_project_id and project_id will be the same and source_project_id will be the fork project's ID.

Get single MR

Shows information about a single merge request.

Note: the changes_count value in the response is a string, not an integer. This is because when an MR has too many changes to display and store, it will be capped at 1,000. In that case, the API will return the string "1000+" for the changes count.

GET /projects/:id/merge_requests/:merge_request_iid

Parameters:

• id (required) - The ID or URL-encoded path of the project owned by the authenticated user
• merge_request_iid (required) - The internal ID of the merge request
• render_html (optional) - If true response includes rendered HTML for title and description
• include_diverged_commits_count (optional) - If true response includes the commits behind the target branch
• include_rebase_in_progress (optional) - If true response includes whether a rebase operation is in progress

NOTE: Note: Starting in GitLab 12.8, the mergeability (merge_status) of a merge request will be checked asynchronously when a request is made to this endpoint. Poll this API endpoint to get updated status. This affects the has_conflicts property as it is dependent on the merge_status. It'll return false unless merge_status is cannot_be_merged.

Get single MR changes

Shows information about the merge request including its files and changes.

GET /projects/:id/merge_requests/:merge_request_iid/changes

Introduced in GitLab 13.6, diffs associated with the set of changes will have the same size limitations applied as other diffs returned by the API or viewed via the UI. When these limits impact the results, the overflow field will contain a value of true. Diff data without these limits applied can be retrieved by adding the access_raw_diffs parameter, however, it will be slower and more resource-intensive.

Parameters:

• id (required) - The ID or URL-encoded path of the project owned by the authenticated user.
• merge_request_iid (required) - The internal ID of the merge request.
• access_raw_diffs (optional) - Retrieve change diffs without size limitations.

List MR pipelines

Introduced in GitLab 10.5.0.

Get a list of merge request pipelines.

GET /projects/:id/merge_requests/:merge_request_iid/pipelines

Parameters:

• id (required) - The ID or URL-encoded path of the project owned by the authenticated user

Create MR Pipeline

Introduced in GitLab 12.3.

Create a new pipeline for a merge request. A pipeline created via this endpoint will not run a regular branch/tag pipeline, it requires .gitlab-ci.yml to be configured with only: [merge_requests] to create jobs.

The new pipeline can be:

• A detached merge request pipeline.
• A pipeline for merged results if the project setting is enabled.

POST /projects/:id/merge_requests/:merge_request_iid/pipelines

Parameters:

• id (required) - The ID or URL-encoded path of the project
• merge_request_iid (required) - The internal ID of the merge request

Merge to default merge ref path

Merge the changes between the merge request source and target branches into refs/merge-requests/:iid/merge ref, of the target project repository, if possible. This ref will have the state the target branch would have if a regular merge action was taken.

This is not a regular merge action given it doesn't change the merge request target branch state in any manner.

This ref (refs/merge-requests/:iid/merge) isn't necessarily overwritten when submitting requests to this API, though it'll make sure the ref has the latest possible state.

If the merge request has conflicts, is empty or already merged, you'll get a 400 and a descriptive error message.

It returns the HEAD commit of refs/merge-requests/:iid/merge in the response body in case of 200.

GET /projects/:id/merge_requests/:merge_request_iid/merge_ref

Parameters:

• id (required) - The ID or URL-encoded path of the project owned by the authenticated user
• merge_request_iid (required) - Internal ID of MR

{
  "commit_id": "854a3a7a17acbcc0bbbea170986df1eb60435f34"
}

Cancel Merge When Pipeline Succeeds

If you don't have permissions to accept this merge request - you'll get a 401

If the merge request is already merged or closed - you get 405 and error message 'Method Not Allowed'

In case the merge request is not set to be merged when the pipeline succeeds, you'll also get a 406 error.

POST /projects/:id/merge_requests/:merge_request_iid/cancel_merge_when_pipeline_succeeds

Parameters:

• id (required) - The ID or URL-encoded path of the project owned by the authenticated user
• merge_request_iid (required) - Internal ID of MR

Rebase a merge request

Automatically rebase the source_branch of the merge request against its target_branch.

If you don't have permissions to push to the merge request's source branch - you'll get a 403 Forbidden response.

PUT /projects/:id/merge_requests/:merge_request_iid/rebase

Attribute	Type	Required	Description
id	integer/string	yes	The ID or URL-encoded path of the project owned by the authenticated user
merge_request_iid	integer	yes	The internal ID of the merge request
skip_ci	boolean	no	Set to true to skip creating a CI pipeline

curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/76/merge_requests/1/rebase"

This is an asynchronous request. The API will return a 202 Accepted response if the request is enqueued successfully, with a response containing:

{
  "rebase_in_progress": true
}

You can poll the Get single MR endpoint with the include_rebase_in_progress parameter to check the status of the asynchronous request.

If the rebase operation is ongoing, the response will include the following:

{
  "rebase_in_progress": true,
  "merge_error": null
}

Once the rebase operation has completed successfully, the response will include the following:

{
  "rebase_in_progress": false,
  "merge_error": null
}

If the rebase operation fails, the response will include the following:

{
  "rebase_in_progress": false,
  "merge_error": "Rebase failed. Please rebase locally"
}

Comments on merge requests

Comments are done via the notes resource.
