API vs Webhook
An API is a two-way conversation you initiate whenever you need data. A webhook is the reverse: a message the other system sends you automatically the moment something happens. Both move data between systems, but the trigger comes from a different side.
API
An API (application programming interface) is the agreed way one program asks another for data or an action and gets an answer, so your tools can work together.
Webhook
A webhook is an automatic message one system sends to an address you gave it the moment something happens, like a payment. You stop asking, it tells you.
You, whenever you need something
The other system, the moment an event occurs
On demand, whenever called
Real time, as soon as the event happens
Pulling data or triggering an action
Getting notified instantly (a payment succeeded, a form was submitted)
| Who initiates the request | You, whenever you need something | The other system, the moment an event occurs |
|---|---|---|
| Timing | On demand, whenever called | Real time, as soon as the event happens |
| Typical use | Pulling data or triggering an action | Getting notified instantly (a payment succeeded, a form was submitted) |
