A webhook is a way for one computer program to automatically send a message or data to another program when a specific event happens.
“Webhook” copies the pattern of “web” plus “hook,” modeled after “callback hooks” in programming. It suggests that one service can “hook into” another over the web.
Webhooks let apps talk to each other instantly, like a doorbell that rings next door every time something changes at your house. They’re the hidden messengers behind many “real-time” features users take for granted.
