REST API endpoints for organization members

Note

If you use Enterprise Managed Users, you add members to organizations directly, rather than sending invitations. The operations for managing organization invitations will not work in your enterprise. However, the operations for viewing or managing membership directly will work as expected.

List failed organization invitations

The return hash contains failed_at and failed_reason fields which represent the time at which the invitation failed and the reason for the failure.

This endpoint is not available for Enterprise Managed User (EMU) organizations.
