Create a webhook endpoint

POST/v1/webhook-endpoints

Registers a new webhook endpoint in the credential's organization and mints its signing secret, returned EXACTLY ONCE in this response. The endpoint starts UNVERIFIED (`verified: false`) — call the `verify` action before relying on it; the worker only queues deliveries to enabled AND verified endpoints. The URL is validated at save time (https, port 443, no embedded credentials) — a disallowed URL answers 422 `webhook_url_rejected` and creates NO row. Supports the optional `Idempotency-Key` header; a replayed response includes the ORIGINAL plaintext secret again within the 24h replay window (same tradeoff as `createApiKey`).

Request body

FieldTypeDescription
urlrequiredstringThe https destination URL. Must be https, port 443 (explicit or default), and carry no `user:pass@` credentials — a URL failing this check answers 422 `webhook_url_rejected` with the specific reason and creates NO row.e.g. https://example.com/webhooks/getitdone
event_types"task.created" | "task.updated" | "task.archived"[]Subset of event types to subscribe to. Omit or send an empty array to subscribe to every type.
enabledbooleanDefaults to true.

Response 201

The created endpoint, with its plaintext secret shown once.

Fields

FieldTypeDescription
idrequiredstringStable id of the endpoint.
urlrequiredstringThe https destination URL.
enabledrequiredbooleanFalse when disabled — manually, or auto-disabled after repeated delivery failures (see `disabled_reason`).
event_typesrequired"task.created" | "task.updated" | "task.archived"[]Subscribed event types. An EMPTY array means "every type".
verifiedrequiredbooleanTrue once the `verify` action has proven this endpoint accepts a correctly-signed request.
disabled_reasonrequiredstring | nullWhy the endpoint was auto-disabled, or null when never auto-disabled.
created_atrequiredstring (date-time)ISO-8601 UTC.
updated_atrequiredstring (date-time)ISO-8601 UTC.
secretrequiredstringThe signing secret (`whsec_…`) — shown EXACTLY ONCE. Store it now; it cannot be retrieved again, only rotated. Note: replaying this exact request within the 24h Idempotency-Key window returns this SAME secret again — treat a stored Idempotency-Key as equally sensitive to the secret itself.e.g. whsec_51f3...redacted
