I believe what's happening is that the JSON body isn't in the right format that the API accepts, so it's not going in properly. How can I modify what's within the JSON body through libcURL? I've browsed the examples, tutorials, and mailing-list pages, and I wasn't able to find anything that could help.

Just a guess as to your problem, but CSV != JSON. You probably need to parse the data out of the CSV file and build a JSON document from it according to the specifications of your API, then submit that JSON document. Even if your JSON API expects a POST containing block of raw CSV data, that block will need to at the very least be escaped, quoted, and embedded into a JSON skeleton. (e.g. {"my_csv_data":"aa,ba,ca\nab,bb,cb\nac,bc,cc"} )

You should probably experiment using the curl command-line tool first until you get the API format right before trying to use libcurl.

Here is an example of doing a JSON post via the command-line:

If you need a starting-point for learning more about the JSON format in particular, this is the definitive resource:
