# Device Token Exchange

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

OAuth 2.0 token endpoint for device authorization. Supports multiple grant types: polling for device authorization (device_code) and refreshing tokens (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) — Must be a unique identifier per hardware device, such as a unique hardware serial number. Must be the same as the client id used on initial authorization.
- `client_secret` (string, required) — A static string, provided by Frame.io to be embedded for a device manufacturer/model. Acts as an identifier within Frame.io.
- `grant_type` (enum, required) — Grant type - use 'urn:ietf:params:oauth:grant-type:device_code' for polling, or 'refresh_token' for refreshing an access token
- `device_code` (string, optional) — The device code received from the /v2/auth/device/code endpoint. Required when grant_type is 'urn:ietf:params:oauth:grant-type:device_code'.
- `refresh_token` (string, optional) — A valid refresh_token from a previous authorization. Refresh tokens are valid for 14 days from issuance. Required when grant_type is 'refresh_token'.
