How to create Identity Management users via the Piano API

The endpoint /publisher/user/create does not work for Identity Management, instead the following APIs are used.

Creating new users: id/api/v1/publisher/identity/register with the following parameters: aid, api_token, email, and password

More details about this endpoint, including an example, are available here.
Updating existing users: /publisher/user/update with the parameters: aid (required), first_name, last_name, uid (required), email, and custom_fields

For example:
```
https://sandbox.piano.io/api/v3/publisher/user/update?aid=AID&api_token=XYZ&email=createuser@gmail.com&uid=123&first_name=John&last_name=Doe
```

If you are receiving the error App not configured to create users in response to calling our Piano API, you are probably calling the wrong endpoint, which is not suitable for Identity Management.
