Webhook for Installation Middleware

[The-LukeZ]

It would be great to have some sort of "middleware" for Discord to call before the bot being installed on a guild or user.

I imagine it like this:

User has Authorization Modal open and completes the flow.
Before the app is being added to the guild or user, the configured webhook endpoint gets called

If the Webhook responds with a 200 OK, then everything proceeds as usual. If it responds with 403 Forbidden and a json payload like { error: "You are banned from using the bot for violating it's TOS" } then the user gets an error page shown with something like "You cannot add the bot to you/your server. The app has provided the reason: {reason}".

This would help devs of bigger bots a LOT because you wouldn't have users questioning everything if they would see an actual error instead of the bot leaving immediately as it is now.

What you're describing is already possible by enabling auth code grant, see https://discord.com/developers/docs/topics/oauth2#advanced-bot-authorization

Python code to handle it for reference: https://github.com/xelA/invite

interesting...

Can you say if that also works for user-installed apps? Is the documentation not completed for that?

I assume it's the same as it's also OAuth2, but with an integration_type param and no bot scope.

I need to try that out 🤔
