Answer

Hello,

From the question I understand that you would like to know if it is possible to dynamically pass a value in the callback url for Cognito.

Currently it is not natively possible to pass a dynamic value in the callback url. You can pass multiple different values as callback urls with a maximum amount of 100. If you simply need the id_token/access_token in the callback you can use implicit grant rather than code grant I am attaching the following documentation that goes over the types of grants here [1].

I hope you have a great rest of your day!
