What is a Webhook Endpoint?

A webhook endpoint is a URL that receives webhook event notifications and can trigger an action based on the payload sent in the message.

A webhook endpoint differs from a traditional API endpoint in that the webhook endpoint only receives notifications while an API endpoint receives requests and sends responses.

If an API consumer wants real time updates from their API provider, they can specify a webhook URL where they would like to receive event notifications. This avoids the need for an API consumer to make constant requests and compare subsequent responses to see if anything changed. This is only possible if the API provider offers a webhook feature.

At Svix we make it super easy for API providers to offer their users a world class webhook experience without the headache and cost of setting up infrastructure and building the UI to support it.
