# Check Silent Authentication

POST https://api.pinnacle.sh/network/silent-auth/{requestId}/check
Content-Type: application/json

Complete a Silent Authentication request by exchanging the code returned from the JSON flow. Call this from your server after the user's mobile app fetches `jsonUrl`.

This endpoint returns a terminal verification result. To inspect pending lifecycle states such as `started` or `challenge-issued`, use [Get Network Request](/api-reference/network/get-network-request).

Limited availability. Contact [founders@pinnacle.sh](mailto:founders@pinnacle.sh) to request access.

Reference: https://docs.pinnacle.sh/api-reference/network/check-silent-auth

## Authentication

- `PINNACLE-API-KEY` header (required) — API Key authentication via header

## Request

### Path parameters

- `requestId` (string, required) — Silent Authentication request ID returned by `POST /network/silent-auth`.

### Body (application/json)

This endpoint expects a SilentAuthCheckRequest.

- `code` (string, required) — Code returned by the JSON Silent Auth device flow.

## Response

### 200

Returns the terminal verification status.

- `requestId` (string, required) — Unique Pinnacle ID for a Network API request.
- `status` (enum, required) — Terminal verification result after exchanging a device flow code. `completed` means the phone number was verified; `failed` means the verification did not complete successfully. To inspect pending lifecycle states, use [Get Network Request](/api-reference/network/get-network-request).
  - Allowed values: `completed`, `failed`

## Errors

### 400 Bad Request Error

The request was unacceptable, often due to providing an invalid update.  Errors may originate from invalid payload or from Pinnacle's additional validation checks. For example, providing an URL that cannot be accessed, updating a campaign that is currently being reviewed, updating data that you cannot access, sending a malformed message, and so on.  For `Pinnacle Validation Error` inspect the `error` payload to determine the source of the failure. These errors are likely due to additional validation and business logic checks. For `Request Validation Error` inspect the `description` and `errors` payload to determine the source of failure. These errors are likely due to invalid payload inside the request.

- `CheckSilentAuthenticationRequestBadRequestError`

### 401 Unauthorized Error

The request lacks valid authentication credentials or the provided credentials are invalid.  Ensure you're including a valid API key in the request headers and that your account has the necessary permissions to access this endpoint.

- `error` (string, required) — Human-readable description of the error that occurred, corresponding to the HTTP status code.

### 403 Forbidden Error

Your subscription does not include access to this feature.  This occurs when attempting to use functionality that requires a higher subscription tier. Please upgrade your subscription to access this feature.

- `error` (string, required) — Human-readable description of the error that occurred, corresponding to the HTTP status code.

### 500 Internal Server Error

An unexpected error occurred on Pinnacle's servers while processing your request.  If this error persists, please contact support with the request details.

- `error` (string, required) — Human-readable description of the error that occurred, corresponding to the HTTP status code.

## Types

### ZodError

- `description` (string, required) — Human-readable summary of validation failures.
- `errors` (ZodErrorErrors, required) — Structured dictionary of issues containing two main sections: - `errors`: Array of global validation errors not tied to specific fields - `properties`: Object mapping field names to their specific validation errors, where each field contains an `errors` array

### Error

Standard error response returned when a request cannot be processed successfully.

- `error` (string, required) — Human-readable description of the error that occurred, corresponding to the HTTP status code.

### ZodErrorErrors

Structured dictionary of issues containing two main sections: - `errors`: Array of global validation errors not tied to specific fields - `properties`: Object mapping field names to their specific validation errors, where each field contains an `errors` array
