Generate Refresh Token for OneDrive

(The following steps are part of Microsoft Graph Code Flow).

Step 1. Get an authorization code

To start the sign-in process with the code flow, use a web browser or web-browser control (Any REST calling tool e.g. Postman, SoupUI, Paw, apidApi, JMeter etc.)

  1. Load this URL request.


GET https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id={client_id}&scope={scope} &response_type=code


Note: In a place of common can use TenantID also.


Step 2. Redeem the code to fetch refresh token

(access token is also generated along with Refresh token)

  1. After you have received the authorization code value, you can redeem this code for a set of tokens that allow you to authenticate with the OneDrive API. To redeem the code, make the following Grant Flow request,


POST

https://login.microsoftonline.com/common/oauth2/v2.0/token


Headers: 

Content-Type: application/x-www-form-urlencoded


Body:  x-www-form-urlencoded (key value pair)

client_id={client_id}

code={code}

grant_type=authorization_code
