Webhook

An automated HTTP callback that sends real-time data to another system when a specific event occurs.

A webhook is a mechanism that allows one system to send real-time data to another system via an HTTP POST request when a specific event occurs. Unlike an API where the client polls for data, webhooks push data automatically.

Privacy Considerations

  • Webhooks can transmit personal data — ensure the receiving endpoint is secure (TLS)
  • Validate webhook signatures to prevent spoofing
  • Log webhook deliveries for accountability
  • Consider whether a data processing agreement is needed with the receiving party
