AsyncAPI 2.6 description of Render's outbound webhook surface. Render delivers event notifications by issuing HTTP POST requests with a JSON body to a subscriber URL configured in the Render dashboard. Each event carries a `type` discriminator that identifies the event class (deploy lifecycle, service availability, scaling, configuration, cron jobs, Postgres, Key Value, and persistent disks). Authenticity is established with a Standard Webhooks style HMAC-SHA256 signature delivered in HTTP headers (`webhook-id`, `webhook-timestamp`, `webhook-signature`). Subscribers must respond with a 2xx status code within 15 seconds; failed deliveries are retried with exponential backoff up to eight attempts, with the final attempt occurring approximately 33 hours after the first. After three failures Render sends an email notification; after all attempts fail the webhook is disabled. Source documentation: https://render.com/docs/webhooks

Receive a Render webhook event
Single subscriber endpoint that receives every Render webhook event delivered to the configured destination URL. The `type` field on the JSON body identifies the event class. Render sends one event per HTTP POST and expects a 2xx response within 15 seconds.
