Merge requests API (FREE)

draft was introduced as a replacement for work_in_progress in GitLab 14.0.

merge_user was introduced as an eventual replacement for merged_by in GitLab 14.7.

Every API call to merge requests must be authenticated.

List merge requests

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 mostly returns 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

Merge requests list response notes

Introduced in GitLab 13.0, listing merge requests may not proactively update merge_status (which also affects the has_conflicts), as this can be an expensive operation. If you need the value of these fields from this endpoint, set the with_merge_status_recheck parameter to true in the query.
For notes on merge request object fields, read Single merge request response notes.

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?state=opened
GET /projects/:id/merge_requests?state=all
GET /projects/:id/merge_requests?iids[]=42&iids[]=43
GET /projects/:id/merge_requests?milestone=release
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 always equals target_project_id.

In the case of a merge request from the same project, source_project_id, target_project_id and project_id are the same. In the case of a merge request from a fork, target_project_id and project_id are the same and source_project_id is 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 is capped at 1,000. In that case, the API returns the string "1000+" for the changes count.

Single merge request response notes

The merge_status field may hold one of the following values:
- unchecked: This merge request has not yet been checked.
- checking: This merge request is currently being checked to see if it can be merged.
- can_be_merged: This merge request can be merged without conflict.
- cannot_be_merged: There are merge conflicts between the source and target branches.
- cannot_be_merged_recheck: Currently unchecked. Before the current changes, there were conflicts.
The diff_refs in the response correspond to the latest diff version of the merge request.
Introduced in GitLab 12.8, the mergeability (merge_status) of each merge request is 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 returns false unless merge_status is cannot_be_merged.
references.relative is relative to the group or project that the merge request is being requested. When the merge request is fetched from its project, relative format would be the same as short format, and when requested across groups or projects, it is expected to be the same as full format.
Introduced in GitLab 14.7, field merge_user can be either user who merged this merge request, user who set it to merge when pipeline succeeds or null. Field merged_by (user who merged this merge request or null) has been deprecated.
pipeline is an old parameter and should not be used. Use head_pipeline instead, as it is faster and returns more information.

Get single MR changes

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

Introduced in GitLab 13.6, diffs associated with the set of changes 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 contains a value of true. Diff data without these limits applied can be retrieved by adding the access_raw_diffs parameter, accessing diffs not from the database but from Gitaly directly. This approach is generally slower and more resource-intensive, but isn't subject to size limits placed on database-backed diffs. Limits inherent to Gitaly still apply.

This API returns specific HTTP status codes on failure:

HTTP Status	Message	Reason
`401`	`Unauthorized`	This user does not have permission to accept this merge request.
`405`	`Method Not Allowed`	The merge request is not able to be merged.
`409`	`SHA does not match HEAD of source branch`	The provided `sha` parameter does not match the HEAD of the source.
`422`	`Branch cannot be merged`	The merge request failed to merge.

For additional important notes on response data, read Single merge request response notes.

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 has 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 makes sure the ref has the latest possible state.

If the merge request has conflicts, is empty or already merged, you receive 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

Supported attributes:

Attribute	Type	Required	Description
`id`	integer or string	{check-circle} Yes	The ID or URL-encoded path of the project owned by the authenticated user.

Cancel Merge When Pipeline Succeeds

This API returns specific HTTP status codes on failure:

HTTP Status	Message	Reason
`401`	`Unauthorized`	This user does not have permission to cancel this merge request.
`405`	`Method Not Allowed`	The merge request is already merged or closed.
`406`	`Not Acceptable`	The merge request is not set to be merged when the pipeline succeeds.

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

Supported attributes:

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

`id`	integer or string	{check-circle} Yes	The ID or URL-encoded path of the project owned by the authenticated user.
`merge_request_iid`	integer	{check-circle} Yes	The internal ID of the merge request.
`skip_ci`	boolean	{dotted-circle} 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 returns a HTTP 202 Accepted response if the request is enqueued successfully, with a response containing:

  "merge_error": null
}

After the rebase operation has completed successfully, the response includes the following:

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

If the rebase operation fails, the response includes the following:

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