Invitations API (FREE)

Use the Invitations API to invite or add users to a group or project, and to list pending invitations.

Valid access levels

To send an invitation, you must have access to the project or group you are sending email for. Valid access levels are defined in the Gitlab::Access module. Currently, these levels are valid:

  • No access (0)
  • Minimal access (5) (Introduced in GitLab 13.5.)
  • Guest (10)
  • Reporter (20)
  • Developer (30)
  • Maintainer (40)
  • Owner (50). Valid for projects in GitLab 14.9 and later.

NOTE: From GitLab 14.9 and later, projects have a maximum role of Owner. Because of a known issue in GitLab 14.8 and earlier, projects have a maximum role of Maintainer.
