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: 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"}) => # irb(main):004:0> I can’t even get this to work: 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?

This seems to be working again now - is there some kind of limit or temp bans if too many requests are sent within a specific time-frame? (I was testing so sending quite a few requests.)

…and it’s stopped working again :frowning: All I did was add the following: msg << "Here's the email template:" msg << "\n \n" msg << "Hi username!" msg << "\n \n" msg << "Guess what!? You won last month's giveaway :-)" msg << "\n \n" msg << "Please send me your:" msg << "\n \n" msg << "Full name:" msg << "\n \n" msg << "Email address:" msg << "\n \n" msg << "Country of residence:" msg << "\n \n" msg << "And I'll send your details over." msg << "\n \n" msg << "All the best," msg << "\n \n" msg << "Aston" msg << "\n \n" The constructed msg is what’s sent as raw in the params.

given it’s a 422, you are probably not hitting a rate limit. Can you show the full code please ?

also I’ve been looking at Discourse REST API Documentation, where do you see the documentation to send private messages ? I only see a section on how to list private messages.

The full code is in the first post (use Ruby with IRB to run it). Sam has said that PMs are just posts and it’s fine to use the API: [תמונה] Private Message Send API Support A PM is just a type of post, you can create a PM just fine using the API. In fact we are using the API on this very site to create PMs. PM stands for personal message by the way :slight_smile:

Ok I tried various things, and there’s definitely something weird going on. I tried sending a PM to me on meta.discourse.org (using the UI) while inspecting xhr requests, and sometimes I got 422 trying to do so. I haven’t found a common pattern, the only thing I’m changing is the text sent, and it’s always over the char limit, and yet sometimes I get a 422.

anyway you can look at the response body and not just the status code? The response body should still return json with an “errors” section that could explain what is going on: example: {"action":"create_post","errors":["Your error message here for a 422 status code"]}

[תמונה] AstonJ: curl https://forum.com/posts?api_key=12345&api_username=MyForum&archetype=private_message&title=title&raw=message&target_usernames=Me also I think your your curl command is wrong because you aren’t specifying a POST request and/or your messages content isn’t url encoded. Your curl command should be changed to look like this: curl -X POST -d api_key="" -d api_username="discourse1" -d target_usernames="discourse2" -d archetype="private_message" -d title="my sample title" -d raw="This is a post to a topic." http://localhost:3000/posts

I thought about it later, and I’m pretty sure he is hitting a 422 while doing his tests because he is sending the same requests, so the content body of his 422 is probably “Body is too similar to what you recently posted”.

[תמונה] j.jaffeux: because he is sending the same requests I thought the same thing, and so I tried sending the same request over and over and it still returns a 200 with the same id (does not create a new pm).
