How to See the API Request Body Sent by HTTPCaller

Hi exc,

This is indeed a problem with the http caller transformer. Are you able to share the call you are trying to make or is it sensitive information? What i usually do is try to send the most barebones call to the API that should work and check the response. Usually I hope to get a not authorized page, if I don't then I try to tweak the url and the headers. Then I add my authorization, and then I add the body that contains information that the API call needs to function.

What I do this way is 1: check if my url is correct, 2: check if the authorization is correct and 3: check if the body layout is correct. This way you can sort of find where you have a problem. 

I hope this helps you a little bit with tracking down your problem.

I was typing out this follow up question to jkr_wrk:

Can you please elaborate on this?

** It will give back what FME sent as a JSON “file”? **
Where do I find that file? When doing this, I do not find any difference to what is in the Transaction Log.

However, I then noticed I got an Output result, rather than a <Rejected> result.  The Output _response_body field (default) has the header info in it.

This allowed me to determine that the FME web connection stores an obtained access token in the variable named [TOKEN].

This was very helpful in determining how to configure API Call Parameter-Header Format for a custom web service based on the Token template:

     Authorization: Bearer [TOKEN]
