I'm trying to learn more about working with APIs. I thought it would be fun to use Zamzar to convert files. Their documentation is here. They've made it super easy and supplied the curl command I should use:
curl https://sandbox.zamzar.com/v1/jobs \
-u my API key: \
-X POST \
-F "source_file=@/tmp/portrait.gif" \
-F "target_format=png"
where I put in my actual API key that I got for free yesterday. When I setup the download tool, I can't quite figure out how to setup the -F part. Here is my attempt on the payload tab:

The response back from the API is :
{"errors":[{"context":{"parameter":"source_file"},"code":10,"message":"no value was specified for a mandatory parameter"}]}Any ideas on how to get this to work? I tried using Curl.exe instead of the download tool, but I'm getting this error:
curl: (1) libcurl was built with SSL disabled, https: not supported!
