hi Brian, that line above seems to be included in the "headers" section but I think it should go in some sort of "body" section (I do not know if there is one).
Progress! I figured it out and wanted to post the solution for others. Rather than the "body" tag or my "data-raw" tag... I just needed to add the email and password to the "json" tag and everything works now, I get my 200 SUCCESS! back from the MEATER Cloud API and it is returning my auth token that I can now parse out of the response!
