An automatic message one system sends another when an event occurs.
A notification one tool sends the moment something happens.
What It Is
Webhook is a Technology item, filed under Integration. What it actually refers to is an automatic message one system sends another when an event occurs.
It is a mechanism rather than an opinion: set up properly it behaves predictably, and set up badly it fails just as predictably. That definition is deliberately narrow — the narrowness is what makes it usable.
How It's Used
Most of the time Webhook is used in build decisions, tooling and the plumbing behind a working system. It rarely travels alone — expect it next to API, Integration and Automation. The practical test is whether it is configured, documented and actually working.
Why It Matters
Ignoring Webhook rarely fails loudly — it fails slowly. When it is unclear, small technical debts compound into a rebuild. The businesses that treat it seriously spend less time redoing work.
It is a piece of machinery doing one job in the background. A notification one tool sends the moment something happens.
Termshift™
How the meaning shifts depending on who is using it, and where.
In agency and in-house rooms, Webhook means exactly an automatic message one system sends another when an event occurs.
In plain conversation it comes out as a notification one tool sends the moment something happens.
The Bottom Line
Webhook pays off when it is specific and costs you when it is not. A notification one tool sends the moment something happens.
