• If the developer wishes to implement the account linking UI directly (or does not want to use the default account linking UI), an account linking API is provided for each IDP.

  • The developer should place account linking buttons for each IDP on the account linking screen, and implement the logic so that clicking each button calls the corresponding IDP's account linking API.

This is an example of linking accounts without using the default account linking UI.
If account linking is successful, the player ID will remain the same.
