Add basic support for threads

[GeniusTimo]

Hey there 👋

This pull request is quite incomplete, but I wanted to leave this as a suggestion to provide support for sending webhook messages within threads. Perhaps my solution is as simple as suggested but I have not tested this yet - in addition, it lacks any documentation.

Hopefully I'm not the only one looking for a thread-only webhook ✌

@GeniusTimo is attempting to deploy a commit to the Sentry Discord Team on Vercel.

A member of the Team first needs to authorize it.

Oh interesting. I actually don't know how threads and webhooks work within Discord - is it a webhook on a channel with just the thread_id param passed in?

[GeniusTimo]

Yes! https://discord.dev/resources/webhook#execute-webhook

Sweet! I will try to take a look at this sometime this week, but I might be a little too busy to get to it - I'm heading out on an international trip for a week, so this might sit until the second week of September, sorry :(

[GeniusTimo]

No problem, have a nice vacation ✈

Any chance this could be merged? From my experience with the Discord API, the PR looks good to me.

I can play around with extending the functionality later - it'd be useful to create a new thread based on the Sentry issue and add subsequent messages to the same thread. With this current PR everything would just be in a single thread. It'll take some querying of the Discord channel but it should be doable.

Yeah! Lemme do a little bit of testing on it and I will get it in sometime this week. Probably gonna need to get to the other side of July 4th first, but after that I'll try and get it out quickly. Sorry, I guess I lost track of this PR - thank you for the reminder bump

[IanMitchell]

Merged into Main, should be deployed soon!

[GeniusTimo]

Thank you!
