A simple integration that lets external applications post messages into Slack channels via a unique HTTP URL. The application sends a JSON payload (with message text and options) to the webhook URL, and Slack posts it to the channel. Trading bots use Slack webhooks to send alerts or reports to team workspaces. For example, after executing a trade, a script could POST trade details to the Slack webhook URL. The Slack docs explain that incoming webhooks “are a way to post messages from apps into Slack… by sending a JSON payload”. Developers configure the webhook and format the JSON; traders then see automated updates in their Slack channels.
