# Scambio del token del dispositivo

POST https://api.frame.io/v2/auth/token
Content-Type: multipart/form-data

Endpoint del token OAuth 2.0 per l’autorizzazione del dispositivo. Supporta più tipi di concessione: polling per l’autorizzazione del dispositivo (device_code) e aggiornamento dei token (refresh_token).

Reference: https://next.developer.frame.io/camera-to-cloud/api-reference/authentication/auth-device-token

## Request

### Body (multipart/form-data)

This endpoint expects a multipart form.

- `client_id` (string, required) — Deve essere un identificatore univoco per singolo dispositivo hardware, ad esempio un numero di serie univoco per l'hardware. Deve essere lo stesso ID client usato nell’autorizzazione iniziale.
- `client_secret` (string, required) — Una stringa statica fornita da Frame.io per l’inserimento per un produttore/modello di dispositivo. Agisce come identificatore all’interno di Frame.io.
- `grant_type` (enum, required) — Tipo di concessione: usa 'urn:ietf:params:oauth:grant-type:device_code' per il polling o 'refresh_token' per aggiornare un token di accesso
- `device_code` (string, optional) — Codice del dispositivo ricevuto dall’endpoint /v2/auth/device/code. Obbligatorio se grant_type è 'urn:ietf:params:oauth:grant-type:device_code'.
- `refresh_token` (string, optional) — Un refresh_token valido di un’autorizzazione precedente. I token di aggiornamento sono validi per 14 giorni dopo l’emissione. Obbligatorio se grant_type è 'refresh_token'.
