Frequently asked questions

What is the difference between a webhook and an API?

Both move data between systems, but the direction of the first move differs. With an ordinary API call your program asks and the service answers. With a webhook the service contacts your program without being asked, because an event occurred. Webhooks are often described as part of a service's API.

What is the difference between a webhook and polling?

Polling means repeatedly asking a service whether anything has changed, which wastes requests and adds delay. A webhook removes the asking: the message arrives when the event happens.

Do webhooks need to be secured?

Yes. Because a webhook address is contacted from outside, receiving systems normally verify that a message genuinely came from the expected sender, commonly by checking a signature the sender includes.
