Hi, I’d love the ability to merge data (primarily bearer tokens) into a header or an auth field, it would be great to start a flow with generating a token and then being able to pass that value directly into an API call 
It sounds like what you’re trying to do is use expiring access tokens, and good news, Parabola now supports this! Every time your Parabola Flow runs, we grab a fresh token that is then inserted into your API request. Read more about this here: How to use the API integration in Parabola.
