Refresh OneNote OAuth2 Access Token

See more OneNote Examples

Refreshes a OneNote OAuth2 access token. When an access token expires, HTTPS requests will receive a 401 status response indicating failure. When that happens, your application can run this code to refresh the access token, and then retry the request using the new access token. Refreshing an access token does not need user interaction (i.e. does not need to display a browser to have the user interactive authorize access). React Native

import { JsonObject, OAuth2, StringBuilder } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // It is assumed we previously obtained an OAuth2 access token.
  // This example loads the JSON access token file 
  // saved by this example: Get OneNote OAuth2 Access Token

  const jsonToken = new JsonObject();
  try {
    jsonToken.loadFile('qa_data/tokens/oneNote.json');
  } catch {
    console.log('Failed to load APP.json');
    return;
  }

  // The access token JSON looks like this:

  // {
  //   "token_type": "Bearer",
  //   "scope": "openid profile User.ReadWrite Notes.ReadWrite Notes.Create User.Read Mail.Send Mail.ReadWrite Files.ReadWrite Calendars.ReadWrite Group.ReadWrite.All",
  //   "expires_in": 3600,
  //   "ext_expires_in": 3600,
  //   "access_token": "...",
  //   "refresh_token": "...",
  //   "id_token": "..."
  // }

  const oauth2 = new OAuth2();

  oauth2.tokenEndpoint = 'https://login.microsoftonline.com/common/oauth2/v2.0/token';

  // Replace these with actual values.
  oauth2.clientId = 'MICROSOFT-GRAPH-CLIENT-ID';
  // This is your app password:
  oauth2.clientSecret = 'MICROSOFT-GRAPH-CLIENT-SECRET';

  // Get the "refresh_token"
  oauth2.refreshToken = jsonToken.stringOf('refresh_token');

  // Send the HTTP POST to refresh the access token..
  try {
    await oauth2.refreshAccessTokenAsync();
  } catch {
    console.log(oauth2.lastErrorText);
    return;

  jsonToken.updateString('access_token', oauth2.accessToken);
  jsonToken.updateString('refresh_token', oauth2.refreshToken);

  // Save the new JSON access token response to a file.

  jsonToken.emitSb(sbJson);
  sbJson.writeFile('qa_data/tokens/oneNote.json', 'utf-8', false);
