    Definition

    What is Webhook?

    A webhook is an automated message sent from one app to another when an event happens, delivering data to a URL in real time so systems can react without constantly polling for changes.

    A webhook is a push notification between systems. When something happens in the source app (a deal is won, a form is submitted) it immediately sends an HTTP request with the details to a URL you provide.

    Webhooks are efficient because the receiving system does not have to keep asking "did anything change?" It simply waits to be told. They are a common building block for integrations and automations.

    Atlas supports webhooks so events in the workspace can trigger actions in other tools instantly, alongside a REST API for two-way integration.

    FAQ

    Questions, answered.

    What is the difference between a webhook and an API?
    An API is something you call to request data. A webhook is the reverse: the source system calls you automatically when an event happens, pushing data to your URL in real time.
    What are webhooks used for?
    Webhooks are used to trigger actions in other systems the moment an event occurs: syncing data, sending notifications, or kicking off automations without polling.
