Http trace for a post

Well, I then got a bad CSRF error …

but that post told me that I also need to include the api_key and api_name in the URL!

POST /posts.json?api_key=..very.long.api.key&api_username=thatsme HTTP/1.0
Accept: */*
Accept-Charset: utf-8
Host: www.rebolchat.me
User-Agent: REBOL
Content-Type: application/json
Content-Length: 234

{"title":"Bot Test","topic_id":36,"raw":"this is an api test that I am trying to see if I can make a post and it needs to be 20 characters","category":8,"name":"Graham","color":"49d9e9","text_color":"f0fcfd","created_at":"2017-05-19"}

And this works.
