Webhooks API

Create webhooks, read their deliveries, and recover what a receiver missed. These endpoints are the /api/webhooks write plane of a self-hosted instance; the guide to receiving and verifying is Webhooks.

List webhooks

GET/api/webhooksSelf-hosted instances
Open .md

Every webhook on this instance, newest first, with status and last delivery times. Paged by offset.

Filters

_offsetinteger#

Rows to skip. Default 0.

Range and paging

_limitinteger#

Page size, 1 to 200. Default 50.

Returns

A cursor envelope. data holds Webhook summary objects.

  • 200One page of webhooks
  • 401This bind requires the instance token, and it was missing or wrong

Create a webhook

POST/api/webhooksSelf-hosted instances
Open .md

Takes triggers and starts at the chain tip, with no backfill. The response carries the signing secret. This is the only time it is returned, so store it now; rotate-secret issues a new one.

Body

namestringrequired#

Unique name on this instance.

urlstringrequired#

Delivery target, http:// or https://. Private addresses are refused at delivery time.

triggersarray of ChainTriggerrequired#

1 to 50 triggers. An event matching any of them is delivered.

formatenum#

Payload and signing format. standard-webhooks signs with the webhook's secret; the others shape the body for that receiver.

6 possible values
standard-webhooksinngesttriggercloudflarecloudeventsraw
authConfigobject#

Per-format receiver credentials: token / tokenEnc for trigger and cloudflare, headers or basicAuth for raw. Write-only — never returned; a read gets auth instead.

Replay a block range

POST/api/webhooks/{id}/replaySelf-hosted instances
Open .md

Queues historical events in a block range for redelivery, capped at 100,000 blocks. Replays are idempotent: the same range yields the same replayId and delivers nothing twice unless force is set. They drain through a 10% share of the outbox so live traffic keeps priority, and never move the live cursor. Replays deliver the normal chain.<type>.apply envelope. Watch one with GET /api/webhooks/{id}/replays/{replay_id}.

Path parameters

idstringrequired#

Webhook id (UUID), as returned by create or list.

Body

fromBlockintegerrequired#

First block, inclusive.

Requeue dead events in bulk

POST/api/webhooks/{id}/dead/requeueSelf-hosted instances
Open .md

Moves dead events back to pending with their attempt counts reset, at live priority. With no body it requeues every dead event of the webhook; replayId narrows it to one replay and since to events that failed at or after that time. A replay that gets events back returns to running, so its progress tracks the retry.

Path parameters

Webhook id (UUID), as returned by create or list.
