The -X option is redundant here.

And this can be dangerous, as it sets expectations on the receiver that libcurl
won't necessarily honour. Better let libcurl itself handle the protocol-level
work on its own.

This doesn't look like a standard HTTP header; are you sure it's correct?

You'll have to clarify what exactly you're trying to accomplish here; HTTP has
no concept of attachments. If you're considering the data field in the JSON
body an attachment, then you'll have to build it in your app to feed libcurl
in a similar way to how you're building it in the shell to pass to curl on the
command-line. You're on the right track where the code says // build json
stream here. If it's a huge file that you don't want to build in a temporary
string first, you can pass it in one piece at a time with a
CURLOPT_READFUNCTION, but you don't have to.
