Merge requests API

Every API call to merge requests must be authenticated.

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, or merged) or all of them (all). The pagination parameters page and per_page can be used to restrict the list of merge requests.

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.

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, 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 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.

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.

Create MR

Creates a new merge request.

POST /projects/:id/merge_requests
Attribute Type Required Description
id integer/string yes The ID or URL-encoded path of the project owned by the authenticated user
source_branch string yes The source branch
target_branch string yes The target branch
title string yes Title of MR
assignee_id integer no Assignee user ID
description string no Description of MR
target_project_id integer no The target project (numeric id)
labels string no Labels for MR as a comma-separated list
milestone_id integer no The ID of a milestone
remove_source_branch boolean no Flag indicating if a merge request should remove the source branch when merging
approvals_before_merge integer no Number of approvals required before this can be merged (see below)
squash boolean no Squash commits into a single commit when merging

If approvals_before_merge is not provided, it inherits the value from the target project. If it is provided, then the following conditions must hold in order for it to take effect:

  1. The target project's approvals_before_merge must be greater than zero. (A value of zero disables approvals for that project.)
  2. The provided value of approvals_before_merge must be greater than the target project's approvals_before_merge.
