Create Webhook Endpoint

Create a new webhook endpoint. The response includes a signingSecret that is only returned once — store it securely for verifying webhook signatures.

The enabledEvents array specifies which global event types this endpoint should receive. Use the Webhook Events reference to see available event types.

To subscribe to events scoped to a specific resource (e.g., a single extractor or workflow), use Create Webhook Subscription after creating the endpoint.

Create a new webhook endpoint. The response includes a `signingSecret` that is only returned once — store it securely for verifying webhook signatures. The `enabledEvents` array specifies which global event types this endpoint should receive. Use the [Webhook Events](https://docs.extend.ai/2026-02-09/developers/api-reference/webhook-events) reference to see available event types. To subscribe to events scoped to a specific resource (e.g., a single extractor or workflow), use [Create Webhook Subscription](https://docs.extend.ai/2026-02-09/developers/api-reference/endpoints/webhook/create-webhook-subscription) after creating the endpoint.

The URL that webhook events will be sent to.

namestringRequired>=1 character

A human-readable name for the webhook endpoint.
