What are Webhooks?

Webhooks are user-defined HTTP callbacks to a specific event in the system. They are automated and are used to send notifications when the event is triggered in the source system. Then a destination system receives payloads of data via webhooks. In other words, webhooks allow sharing of information about the occurred event between integrations and the source system.

Key Components of Webhooks

  • Trigger - the event that causes a webhook to fire;

  • URL - the specified listener in the form of an HTTP request which receives the webhooks and performs a predetermined action afterward;
  • The payload - the message about the triggering event the webhook sends;

  • Headers -  supplemental information to pass, e.g. authentication.
