Hi,
When I call standard M3 API from Postman I use Auth 2.0 and Password credentials, everything works fine.
I have setup a simple API flow in ION, I can call it from "API documentation > try it out", it works fine.
Now I am trying to call same API flow endpoint from Postman (using Auth 2.0 and Password credentials) but call it just expires.

What am I missing?
Regards
Kirill
