What is expiresOn and extExpiresOn in result of acquireTokenByCode function call?

Question

First I am calling getAuthCodeUrl And then handling callback.

Here is my function that handles the callback after user login

async handleCallback(code: string): Promise<{ accessToken: string; refreshToken: string }> {
  const tokenRequest = {
    scopes,
    code,
    redirectUri,
    accessType: 'offline',
  };

  try {
    const authResult = await this.cca.acquireTokenByCode(tokenRequest);
    console.log('authResult: ', authResult);

    const accessToken = authResult.accessToken;
    const refreshToken = this.getRefreshToken();

    return { accessToken, refreshToken };
  } catch (error) {
    console.error('Error obtaining access token:', error);
    throw new Error('Error obtaining access token');
  }
}

In result of cca.acquireTokenByCode I am getting expiresOn and extExpiresOn with different values
expiresOn: 2024-03-19T14:38:04.000Z,

extExpiresOn: 2024-03-19T15:38:04.000Z,

I want to know what these 2 stands for. I read that msal-node But I didn't find details on result of function call.

Answer 1

'expiresOn' and 'extExpiresOn' are two properties related to token expiration. The first one shows the standard expiration time, while the second one shows any extended expiration time that may apply in some scenarios. This allows the application to handle token renewal properly.
