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.
