Knock has introduced a new webhook channel to enhance its notification engine, allowing users to notify any HTTP service while benefiting from Knock's preference management, retry logic, and observability. This feature supports two main use cases: notifying internal or third-party services and powering customer-facing webhooks, addressing customer demands for more flexible notification workflows. Users can configure the webhook channel by setting the URL, headers, parameters, and body data, and integrate it seamlessly into existing workflows. Knock manages retry logic and request logging, and offers features like signature verification for secure communications. The webhook channel is available across all Knock plans, including the free Developer plan, and notifications sent through it contribute to overall usage volume. Users can manage preferences for webhook notifications as with other Knock channels, ensuring a cohesive experience.
