Anyone know what I am doing wrong here please? It was working fine, then I don’t know what I did but it stopped working. I’ve stripped it back to this and it’s still not working:

```plaintext
irb> require 'uri'
=> true

irb> require 'net/http'
=> true

irb> Net::HTTP.post_form(URI.parse("https://forum.com/posts?api_key=12345&api_username=MyForum"), {title: "test", raw: "test", archetype: "private_message", target_usernames: "Me"})

=> #<Net::HTTPUnprocessableEntity 422 Unprocessable Entity readbody=true>
irb(main):004:0> 

```

I can’t even get this to work:

```plaintext
curl https://forum.com/posts?api_key=12345&api_username=MyForum&archetype=private_message&title=title&raw=message&target_usernames=Me

```

Any idea what’s going on?
