Hello,
I have a API request working in postman, but cant get it to work via FME.
If I could see the request headers/body, etc I would be able to debug the issue by comparing the working request vs the fme request.
Does anyone have any ideas how I can see this?
Thanks

How to See the API Request Body Sent by HTTPCaller

You can change the requested URL in the HTTPCaller to this URL:
or POST etc.
This will give back what FME send as JSON file. And you can analyse this to see if FME did something unexpected.

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]
