Delete merge request level rule

Note: This API endpoint is only available on 12.3 Starter and above.

You can delete merge request approval rules using the following endpoint:

DELETE /projects/:id/merge_requests/:merge_request_iid/approval_rules/:approval_rule_id

Important: Deleting a report_approver or code_owner rule is not allowed. These are system generated rules.

Parameters:

Attribute Type Required Description
id integer yes The ID of a project
merge_request_iid integer yes The ID of MR
approval_rule_id integer yes The ID of a approval rule

Approve Merge Request

Note: This API endpoint is only available on 8.9 Starter and above.

If you are allowed to, you can approve a merge request using the following endpoint:

POST /projects/:id/merge_requests/:merge_request_iid/approve

Parameters:

Attribute Type Required Description
id integer yes The ID of a project
merge_request_iid integer yes The IID of MR
sha string no The HEAD of the MR
approval_password (STARTER) string no Current user's password. Required if Require user password to approve is enabled in the project settings.

The sha parameter works in the same way as when accepting a merge request: if it is passed, then it must match the current HEAD of the merge request for the approval to be added. If it does not match, the response code will be 409.
