Protected branches API (FREE)

Introduced in GitLab 9.5.

Valid access levels

The access levels are defined in the ProtectedRefAccess.allowed_access_levels method. Currently, 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 project as they are defined in the UI. If a wildcard is set, it is returned instead of the exact name of the branches that match that wildcard.

GET /projects/:id/protected_branches

Attribute	Type	Required	Description
`id`	integer/string	yes	The ID or URL-encoded path of the project owned by the authenticated user
`search`	string	no	Name or part of the name of protected branches to be searched for

Example with user / group level access (PREMIUM)

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.
