Webhooks send real-time events between systems (like opens, clicks, or replies). Learn what webhooks are and how they power automation.
A webhook is a way for one application to send real-time data to another when an event happens. Instead of repeatedly polling an API, a webhook pushes information immediately, such as when a user submits a form or when an email event occurs.
In email workflows, webhooks can trigger automations like updating a CRM when a lead replies, moving contacts into a sequence after a click, or notifying a team when a high-priority message arrives.
Webhooks should be secured with signed payloads, retries, and idempotency to prevent duplicate processing. When implemented well, they make automations faster, more reliable, and easier to maintain.
