Callback URL for oAuth

[Venus]

I need to call TD Ameritrade API which requires oAuth tokens and Refresh tokens , to build that flow, we need a callback URL hosted by appsheet so it can receive the token back and use it for subsequent API calls.

Does Appsheet support such a setup ? if so, where could i get the Appsheet's callback URL ?

Afaik, AppSheet doesn't support any oAuth via API.
AppSheet cannot read any response, it's fire and forget
