Steps
Request webhook access from Spark API support or your API key provider, since this is a permissioned feature not enabled by default
Once approved, register a webhook endpoint URL to receive POST requests for news feed events in place of email or device notifications
Verify your endpoint responds quickly with a success status so Spark doesn't treat deliveries as failed
Parse incoming POST payloads to identify the event type and affected listing or resource
Implement idempotent handling on your endpoint in case of retried webhook deliveries
Known gotchas
Webhook access is gated behind a special permission request; a standard Spark API key does not include webhook/news-feed push access by default
Since webhooks replace email/push notifications, existing polling-based notification logic must be fully migrated, not run in parallel, to avoid duplicate handling
