What is Webhook?
An automatic message one app sends another the moment something happens, such as a new booking or a paid invoice, so the next step can start instantly.
With an API, your system has to ask “anything new?”. With a webhook, the other app tells you the instant something happens. A form is submitted, a call ends, a payment clears: the app sends a small message to an address you choose, and your workflow starts right away.
Why it matters
Speed. Webhooks are how a lead gets a text within seconds of filling in a form, how a booking appears in your CRM before the client has closed the tab, and how a paid invoice triggers the welcome email without anyone checking.
In practice
Most automation tools give you a webhook address to paste into the other app’s settings. If a tool you are considering offers webhooks, it will be much easier to connect.
