How to call Anon Module Piano APIs for UserRef

To call this API you would need to pass the UserRef token you use to authorize the user as a parameter like this:

user_token=<userref>

And set an additional parameter to indicate the UserRef configuration:

user_provider=publisher_user_ref

For example:

https://api.piano.io/api/v3/access/list?aid=<AID>&amp;user_token=<userref>&amp;user_provider=publisher_user_ref

In case your application's dashboard has another locale, the available base URLs are listed here.
