Google Action，帐户关联：身份验证后插入代码

Question

I've implemented Account linking via Auth0 for my Google Action. It works, but I need the user to insert a specific code just after the authentication, and have this code sent back to the action as variable. How can I manage this task?

I'm developing the action in Dialogflow. The authentication works.

The short answer is no. There is no part of the OAuth protocol that allows additional payload that has meaningful information.

However, you should be able to do this through Auth0 itself. You can add custom claims that are stored as part of the userinfo. Then, when you get the auth token from your action, use this auth token to get the user profile (including the code) from Auth0.
