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 deletes any subscription of the account. * **`Idempotency-Key`:** not honored. A second call for the same id returns `404 not_found`. * **Events:** none. No event announces the deletion. * **Guide:** [Deleting a subscription](/webhooks/delivery#deleting-a-subscription). The deletion is permanent: the delivery records are deleted with the subscription, the requests not sent are dropped, and the events that only this subscription received leave the events feed. The operation returns `204` with no body. ## Errors | Status | `error.code` | When | | - | - | - | | 400 | `validation_failed` | `id` is not `wh_` followed by 25 letters or digits. | | 404 | `not_found` | Your account has no subscription with this id, or it is already deleted. | The errors that every operation shares are in [Errors](/errors-and-rate-limits#errors). ## OpenAPI ````yaml DELETE /v1/webhooks/{id} 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/{id}: delete: summary: Delete a webhook subscription description: >- Deletes a webhook subscription, its signing secret and its delivery records.
