The OCS Registration API allows you to register for an account, check the status of the registration and get initial login credentials from within clients.
The base URL for all calls to the API is: <nextcloud_base_url>/ocs/v2.php/apps/registration/api/v1
If cloud providers implement that api they need to provide all of the endpoints described in the following.
All calls to OCS endpoints require the OCS-APIRequest header to be set to true.
