API connector error header name not correct

My apologies I am a newbie here but I have a little knowledge. I am coming over from Podio.

The Podio API is a two stage API you 1. need a token and then secondly you make another PAI call to get the info you need. In Hurl.it all works fine but inside Bubble I am really pulling my hair out. I get the above error.

Appreciate a little direction … may thanks.
