A webhook subscription isn't delivering events to your endpoint, or deliveries are failing. ## Quick checks * Open **Settings > Integrations > Webhooks**, expand the subscription, and read its delivery log first — the status, response code, and error on each attempt point straight at the cause. ## Cause: the subscription is disabled **How to check:** Confirm **Enabled** is on for the subscription. **How to fix:** Turn it on, then replay any deliveries you missed from the delivery log. ## Cause: the event type isn't subscribed **How to check:** If you never see a delivery row at all for an event you expect, the subscription's event types don't include it — see the [event catalog](/developers/webhooks/event-catalog). **How to fix:** Add the event type to the subscription. ## Cause: your endpoint is unreachable **How to check:** The delivery log's error mentions a connection failure, timeout, or DNS error rather than a response code. **How to fix:** Confirm the URL is correct and reachable from the public internet — not an internal-only address. ## Cause: your endpoint returned a non-2xx response **How to check:** The delivery log shows the response code your endpoint sent. **How to fix:** A 401 usually means signature verification is failing on your end — see [Verify signatures](/developers/webhooks/verify-signatures). A 4xx or 5xx means your endpoint rejected or errored on the payload; check your endpoint's own logs. ## Cause: your endpoint was too slow **How to check:** The delivery log shows a timeout with no response code. **How to fix:** Respond within a few seconds. If your processing takes longer, acknowledge immediately and do the work asynchronously. ## Cause: delivery was exhausted after repeated failures **How to check:** The delivery log shows status **Exhausted** — Get2Dial stops retrying after 6 attempts over about 24 hours. **How to fix:** Fix your endpoint, then select **Replay** on the exhausted delivery. ## If none of this worked
