Group-level protected branches API

Tier: Premium, Ultimate Offering: Self-managed
History
  • Introduced in GitLab 15.9 with a flag named group_protected_branches. Disabled by default.
  • Flag group_protected_branches renamed flag to allow_protected_branches_for_group GitLab 15.11.
  • Generally available in GitLab 17.6. Feature flag group_protected_branches removed.

Use the Group-level protected branches API to manage protected branch rules. It provides endpoints to list, create, update, and delete protected branch rules that apply to projects within a group.

caution
Group-level protected branch settings are restricted to top-level groups only.

Valid access levels

The access levels are defined in the ProtectedRefAccess.allowed_access_levels method. These levels are recognized: 

0  => No access
30 => Developer access
40 => Maintainer access
60 => Admin access

List protected branches

Gets a list of protected branches from a group. If a wildcard is set, it is returned instead of the exact name of the branches that match that wildcard. 

GET /groups/:id/protected_branches
Attribute Type Required Description
id integer or string yes The ID or URL-encoded path of the group.
search string no Name or part of the name of protected branches to be searched for. 
curl --header "PRIVATE-TOKEN: <your_access_token>" \

Example with user / group level access

Elements in the allowed_to_push / allowed_to_merge / allowed_to_unprotect array should take the form {user_id: integer}, {group_id: integer}, or {access_level: integer}. Each user must have access to the project and each group must have this project shared. These access levels allow more granular control over protected branch access.
