I have an API that I'm trying to hit and pull back data but the problem is that the authorization token that I have to pass in/use to my Rest Client step is dynamic. I.e., I have to make a HTTP Post call to create a new token and then use that new token each time I want to do a "Get" call within my Rest Client step. I have no problem doing the HTTP post and getting the authorization key each time. Currently I am outputting that key to a json file but I can put it in a database or wherever is needed, if needed.

My question is: how do I pass this dynamic authorization key to my Rest Client step? Generally, a Rest Client step has to have a "Generate Rows" step before it, but I can't seem to pass a dynamic value to the "Generate Rows" step. If I could my problem would be solved. Any ideas?
Thanks for the help!
