  • No access (0)
  • Minimal access (5)
  • Guest (10)
  • Reporter (20)
  • Developer (30)
  • Maintainer (40)
  • Owner (50)

email string yes (if user_id isn't provided) The email of the new member or multiple emails separated by commas.

curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" \
     --data "[email protected]&user_id=1&access_level=30" "https://gitlab.example.com/api/v4/groups/:id/invitations"
curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" \
     --data "[email protected]&user_id=1&access_level=30" "https://gitlab.example.com/api/v4/projects/:id/invitations"

Example responses:

When all emails were successfully sent:

{  "status":  "success"  }

When there was any error sending the email:

{
  "status": "error",
  "message": {
               "[email protected]": "Invite email has already been taken",
               "[email protected]": "User already exists in source",
               "test_username": "Access level is not included in the list"
             }
}

NOTE: If administrator approval for role promotions is turned on, membership requests that promote existing users into a billable role require administrator approval.

To enable Manage non-billable promotions, you must first enable the enable_member_promotion_management application setting.

Example response:

{
  "queued_users": {
    "username_1": "Request queued for administrator approval."
  },
  "status": "success"
}
