How do I debug API interceptor?

Database & APIs

I have an interceptor that encodes authentication header

When I run a API call with default code, I get 400 error, and header is clearing showing no authorization defined.

What is the best way to debug this other than deploying to webservice to check this?

What have you tried so far?

I have tried deploying to dev, but I want to see the actual behavior of this interceptor.

Did you check FlutterFlow's Documentation for this topic?
