To request an access token, your application should send the this request. Store both the `access_token` and the `refresh_token`. The access token can be used immediately to make authenticated requests but it expires after the `expires_in` seconds. The refresh token can be used to refresh both tokens. {% hint style="info" %} **Note:** Be sure to set the `Content-Type` header field of your request to: `Content-Type: application/x-www-form-urlencoded` {% endhint %} A valid request should follow this format (line breaks added for clarity): ``` GET https://garageio.com/oauth/v2/endpoints/token/? client_id=& client_secret=& grant_type=authorization_code& code=& redirect_uri= ``` --- # Agent Instructions This documentation is published with GitBook.
