Create Webhook

Allows authenticated clients to configure webhook endpoints for receiving real-time notifications about operation status changes. The webhook is only activated if the activation test is successful.

Webhook Events: After configuration, your endpoint will receive:

Activation test: See WebhookActivationEvent schema below
Status updates: See OperationStatusUpdateEvent schema below

Note: Only one active webhook is allowed per client. Creating a new webhook will deactivate any existing ones after successful activation.
