A trial key returns `401 unauthorized`. * **Line-scoped keys:** the list of a [line-scoped key](/authentication#line-scoped-keys) is not applied here: the key lists every subscription of the account. * **`Idempotency-Key`:** not needed: the operation changes nothing. See [Retrying safely](/idempotency#retrying-safely). * **Events:** none. * **Guide:** [Subscription states](/webhooks/overview#subscription-states) explains the fields this operation returns and why a suspended subscription still reads `active: true`. The response has no pages and takes no filter. ## Errors This operation has no error of its own. The errors that every operation shares are in [Errors](/errors-and-rate-limits#errors). ## OpenAPI ````yaml GET /v1/webhooks openapi: 3.0.0 info: title: iSnap API version: 2.45.0 description: >- The iSnap API sends and receives iMessage, RCS and SMS on real phone lines, manages those lines, and reports events through webhooks. Every message is sent to a real recipient, with an `isnap_live_` key and with an `isnap_test_` key alike. Retry a `429` after `Retry-After` seconds. Retry a `500` or a `503` up to 2 times, with exponential backoff. Do not retry any other `4xx`: fix the request. Retry a write only on an operation that honors `Idempotency-Key`, with the key of the first attempt. Responses carry personal data: handles, names and message text. servers: - url: https://api.isnap.ai security: - bearerAuth: [] paths: /v1/webhooks: get: summary: List webhook subscriptions description: >- Returns every webhook subscription of the account in one response, newest first, without pagination. Accepts an API key; a line-scoped key lists them all. Signing secrets are not returned. No field reports a suspension, and a suspended subscription still reads `active: true`. Two signs indicate a suspension: `failure_count` is 10 or more, or the deliveries of the subscription stay `pending` with `next_retry_at: null` in `GET /v1/webhooks/{id}/deliveries`. A suspension for a refused URL does not change `failure_count`. Events that occur while a subscription is suspended are not recorded for it: they have no delivery and cannot be replayed. responses: '200': description: The webhook subscriptions of the account. content: application/json: schema: type: object properties: success: type: boolean enum: - true description: Always `true` on a success response. data: $ref: '#/components/schemas/WebhookList' trace_id: type: string description: >- Trace id of the request that produced this response: 32 lowercase hexadecimal characters.
