how to create the refresh token in office 365 using nodejs with office 365 api when the access token get expired

To create a refresh token in Office 365 using Node.js with Office 365 API when the access token gets expired, you can follow the below steps:

1. Install the 'adal-node' library using npm:

npm install adal-node

2. Import the library and create a new instance of the AuthenticationContext:

const AuthenticationContext = require('adal-node').AuthenticationContext;
const authorityUrl = 'https://login.microsoftonline.com/common';
const clientId = 'your_client_id';
const clientSecret = 'your_client_secret';
const resource = 'https://graph.microsoft.com';

const authContext = new AuthenticationContext(authorityUrl);

3. Use the 'acquireTokenWithRefreshToken' method to get a new access token using the refresh token:

authContext.acquireTokenWithRefreshToken(refreshToken, clientId, clientSecret, resource, (err, tokenResponse) => {
    if (err) {
        // Handle error
    } else {
        const accessToken = tokenResponse.accessToken;
        const newRefreshToken = tokenResponse.refreshToken;
        // Use the new access token and refresh token
    }
});

4. You can store the new refresh token for future use, and use the new access token to make API requests.

Note: You need to obtain the initial access token and refresh token by following the OAuth 2.0 authentication flow.
