I would like to set up an activity log on a discord server. They provide a nice and easy way to generate a webhook link, you curl there and a message appears on the chat. They provide three ways of receiving messages: the GitHub way, the Slack way, and the Discord way  I already use things like pipedream  to serve as duct tape in these cases but I want to know if there is something native, like webhooks compatible with GitHub or a workaround that could be done with the GraphQL API  https://discord.com/developers/docs/resources/webhook#execute-webhook  https://pipedream.com
IIUC by policy SourceHut would not spend further resources to integrate with proprietary software; however for most activities you can track an RSS feed.
There is not a snowball's chance in hell of a Discord integration with SourceHut. We provide chat.sr.ht for a reason. Do not use proprietary walled gardens.
