Webhooks
Pass a webhook_url when creating a render and DevMotion will POST the result to your endpoint when the render completes or fails.
Payload
Your endpoint receives a JSON POST body with an event field and the full render object.

}Responding to webhooks
Your endpoint should return a 2xx status code. DevMotion marks the webhook as sent on success or failed on non-2xx responses. There is currently no automatic retry.
Security
Webhook payloads do not include a signature header today. We recommend filtering by IP or verifying the render ID via GET /renders/:id before processing the payload.
