How this service works
Find expired domain names with high traffic and strong SEO backlinks daily. Boost your revenue by searching our database of 13,000,000+ expired domains from auctions, backorders, and dropped lists—complete with rich metrics and domain age.
Output
Returns a confirmation that the ping was sent to the specified webhook subscription, indicating whether the subscription endpoint is reachable and responding. Typically returns an HTTP 200 with a success status or an error if the subscription ID is invalid or the endpoint is unreachable.
Example use cases
Verify new webhook before going live
“I just set up a webhook subscription on Karma.Domains with ID 'sub_xyz789' — can you ping it to make sure it's reachable and working before I rely on it for expired domain alerts?”
Diagnose missed domain alerts
“I haven't been getting any expired domain notifications from Karma.Domains — can you send a test ping to my webhook subscription 'sub_abc456' to see if it's still active?”
Post-deployment webhook health check
“We just deployed a new server — ping our Karma.Domains webhook subscription 'sub_def999' to confirm the new endpoint is responding correctly to subscription events.”
Technical details
Endpoint
POSThttps://api.karma.domains/v1/webhooks/%7Bsubscription_id%7D/ping?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific Karma.Domains webhook subscription is correctly configured and the target endpoint is reachable — especially after initial setup, server migration, or when troubleshooting missing domain alert notifications. This is a targeted health-check, not a search or data-retrieval operation.
