POST /api/groups/{GroupID}/members

Invites a new member to the specified group.

Settings: This operation checks whether the setting that allows group members to invite members who are not already platform users is turned on. If the setting (InviteUnregisteredUsers) is turned off, the operation will fail. To check this setting, run the GET /api/businesses/{BusinessID}/usersettings operation.

Authorization Roles/Permissions: Must be logged in. Must have Modify permission for the resource. For example, a group leader can perform this action.

Workflow: A default workflow is in effect for new group membership objects, unless a custom workflow is specified. By default, when a new group membership object is created, the API invokes the default initial action, @Invite, to start the workflow. This places the new group member in a Pending state. If a custom workflow is used, the custom workflow definition could choose which state the group membership will be placed in. For example, if you wanted to skip the acceptance of the group membership invitation by the invited user, you could develop and implement a custom workflow to skip the Pending state and put the new group membership directly into the Accepted state. For more information on workflow, see Executing Workflow Actions.

Error Codes/Messages

If the call is unsuccessful an error code/message is returned. One or more examples of possible errors for this operation are shown below.

Item Value
401 Unauthorized. For example, you would get this response if you didn't include the custom X-Csrf-Token_{fedmemberID} header in the request, when it was required by the platform settings; or if you included an invalid or expired value for this header. You would also get this response for any operation that requires login (almost all) if the login cookie was missing.
405 Method Not Allowed. For example, you might get this if you specified an invalid Accept header or omitted a required Content-Type header, or used the wrong HTTP verb.
500 An error occurred processing the call.
