Trying to reverse engineer POST requests, how do I 'catch' them?

I can see the response in Developer tools, but I can't see the POST request being sent.

Do I really need to MITM myself to see this?

You should be able to see the contents of POST requests in dev tools. Assuming you're talking about Chrome, under the "Headers" tab of the request detail, there should be a section "Request Payload" which contains the request body.
