  "body": "You're on call for a service that listens to a payment provider's webhooks. At 3am your endpoint is down for a few minutes during a deploy. One event, an order confirmation, never arrives. In the morning a customer writes in, and you open the provider's docs to find out how to get that event back.\n\nThat is the question a recent APIs.io post says most people skip. It looked at the Webhook & Event Subscription Management capability, which maps to 658 providers and 818 API surfaces in the catalog, with 350 of those providers rated strong or better. Registering a webhook, the post says, is close to a commodity. Recovering one that failed is not.\n\nTo test that, the catalog scanned those providers' operations for a write operation on a path that resends, retries, replays or redelivers something event-shaped. It found 85. By band, that is 18 of 137 exemplar providers, 27 of 213 strong, 29 of 176 developing, 7 of 108 thin, 4 of 23 emerging, and 0 of 1 minimal. The shares run from 13 percent in the exemplar and strong bands to 16 percent in developing. Most of every band has no such operation on the record.\n\nThe post is careful about what that number means. Treat 85 as a ceiling, it says. The scan matches on path words, so a few hits are not webhook recovery at all. Cacheflow resending an email and Hover resending notifications for a capture request both got counted. The scan also can't see a provider that retries automatically, or one that offers replay only in a dashboard. What it measures is whether a caller can trigger recovery through the contract.\n\nThe finding that should matter to you is that the Kin Score doesn't separate this. Exemplars do it at 13 percent and developing providers at 16 percent. A high score, the post says, does not tell you a provider has thought about the failed event.\n\nSome providers show what good looks like. Svix has a retry-schedule operation plus bulk-replay and replay-missing on an endpoint. Convoy offers batchretry and forceresend on event deliveries. Fireblocks has POST /webhooks/resend. FirstPromoter and Drippay retry a specific delivery by ID, and GitLab and PayPal resend a single event. Only two providers have a dead-letter path naming webhooks: Kita with GET /api/v1/webhooks/dlq and CertifyOS with POST /webhooks/dlq/drain. The strongest shapes, the post says, treat delivery as a resource.\n\nIt adds that this matters more for agents than for people. An agent that subscribes to events and misses one has no human watching a dashboard. A contract operation is the only recovery path it can find on its own.\n\nThen the post turns on its own record. The catalog's model breaks this capability into three children: Webhook Subscription Lifecycle, Event Schema Catalogue, and Webhook Delivery Reliability Management. All three show no catalog coverage. The mapping stops at level two, so the catalog says nothing structured about delivery reliability, which the post calls the question that matters most. The scan is a stand-in until that changes.\n\nThere is a second disclosure. The agent scores at the top are led by Xquik at 86.9, then Yarnhen and Yawplet at 78.8, then Eventwren and Hagglebee at 73.3. All four are agent-first publishing sites operated by API Evangelist, which publishes the ranking. The post says to read them as a reference implementation, not independent market evidence. Telnyx (87.6, 72.7) and OpenAI (82.6, 58.0) are the stronger independent signals.\n\nWhat you take from it is a better question. Whether a provider has webhooks is settled, since 658 say yes. Ask what happens to the event that failed at 3am, and whether you can fix it with an API call. If you publish webhooks yourself, a list-deliveries and retry pair is a small addition that few of your peers have.\n\nRead the original: https://apis.io/2026/11/07/webhooks-reach-658-providers-but-only-85-show-a-way-to-resend-one/",
