A Discord URL that accepts HTTP POST requests and reposts the payload as a message in a Discord channel. Widely used by game servers as an ad-hoc upload sink, audit log, and admin notification surface.
Discord webhooks were introduced for one-way integrations. A game server posts a screenshot, a ban notification, or a chat line to the webhook URL and it shows up in the target channel. The pattern is free, requires no new accounts, and is supported by virtually every game-server framework
The trade-off is durability. Webhook attachments live inside Discord's message store, subject to channel rolls, accidental deletes, and retention policy changes. Operators who use webhooks as a CDN often find themselves missing evidence months later when they actually need it
Per-script attribution is also limited: one webhook URL is shared by every script writing to a channel, so it is hard to tell which script burned the bandwidth when something goes wrong.
