A webhook is a method used to provide other applications with real-time information. Think of it as an automated messenger. In the context of Slack, a webhook allows external applications to send automatic notifications to your Slack channels.

For example, imagine you have a project management tool. Every time a task gets completed, a webhook could send an update to your team’s Slack channel, sharing this news. It effectively streamlines and automates the communication process.
