What's the correct `content-type` when editing posts?

Doh, of course! Not all GETs require Authorization!
That’s such a nice pointer, I will look into that. Thanks!

Things that I already know by reverse engineering:

  • api-key rather than api_key
  • The PUT request requires "content-type": "application/x-www-form-urlencoded"
  • The data is not in JSON (it’s encoded, although I don’t seem to find the right encoding)
