A trial key returns `401 unauthorized`. See [Typing indicators](/guides/conversations#typing-indicators). * **Line-scoped keys:** the list of a [line-scoped key](/authentication#line-scoped-keys) is not applied: such a key acts on any chat of the account. * **`Idempotency-Key`:** not honored. A repeat asks the device to clear the indicator again. * **Events:** none. * **What reaches the contact:** the line's device clears the indicator when it shows one. An indicator also clears on its own 15 seconds after the last start. ## Errors | Status | `error.code` | When | | - | - | - | | 404 | `not_found` | The chat is unknown, or its line is not yours. | | 422 | `sms_typing_not_supported` | The chat's line is not an iMessage line. | | 422 | `unsupported_handle` | The chat's contact is not a phone number in E.164. | The errors that every operation shares are in [Errors](/errors-and-rate-limits#errors). ## OpenAPI ````yaml DELETE /v1/chats/{chat_id}/typing 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/chats/{chat_id}/typing: delete: summary: Clear the typing indicator description: >- Asks the line's device to clear the typing indicator shown to the chat's contact. Returns `200` with `stopped_at`. The call succeeds even when nothing reaches the contact: when the line has no paired device, and on every shared line, the request is dropped. iSnap sends no event about a typing indicator you clear. The chat must be on an iMessage line and the handle of its contact must be a phone number in E.164: otherwise the API returns `422 sms_typing_not_supported` or `422 unsupported_handle`. Accepts an API key. A line-scoped key can call it for any chat of the lines you own: its `line_ids` are not checked. parameters: - schema: type: string pattern: ^chat_[0-9A-Za-z]{25}$ description: 'Chat id: `chat_` followed by 25 letters or digits.' required: true description: 'Chat id: `chat_` followed by 25 letters or digits.' name: chat_id in: path responses: '200': description: >- The request to clear the typing indicator, accepted for the line's device. content: application/json: schema: $ref: '#/components/schemas/ChatTypingStopEnvelope' '400': description: >- Invalid request. `error.code` is `validation_failed` when a parameter, a header or the body does not match its schema: `error.issues` then lists each problem. content: application/json: schema: $ref: '#/components/schemas/ErrorEnvelope' '401': description: No valid credential. `error.code` is `unauthorized`. content: application/json: schema: $ref: '#/components/schemas/ErrorEnvelope' '403': description: >- Refused. `error.code` is `forbidden`: the request carries neither an API key in its `Authorization` header nor the header `X-Requested-With: XMLHttpRequest`. content: application/json: schema: $ref: '#/components/schemas/ErrorEnvelope' '404': description: >- Not found. `error.code` is `not_found`: the chat does not exist, or its line is not yours. content: application/json: schema: $ref: '#/components/schemas/ErrorEnvelope' '429': description: >- Too many requests. `error.code` is `rate_limit_exceeded` when more than 100 requests came from the same network address in 60 seconds, whatever their API key or account: wait `error.retry_after` seconds. content: application/json: schema: $ref: '#/components/schemas/ErrorEnvelope' '500': description: >- Unexpected failure. `error.code` is `internal_error`.
