Authenticates a customer and fetches their session data.

Guide: Authenticate chat πŸ“™

Visit Authenticate chat to learn how to authenticate chat with a secure JWT token.

If you have embedded our chat widget behind a login, or if you want to allow users to see their past conversations from a different device, you can authenticate them with Kustomer.login().

Kustomer Chat must finish initializing fully with Kustomer.start() before you can execute any additional Web SDK methods.

Tip: Call other methods inside the callback of Kustomer.start() to ensure Kustomer Chat always completes initialization before the code tries to run other methods.

To learn more, see Troubleshooting: Kustomer method calls won't execute.

Examples

We're provided some examples of how you can call Kustomer.login():

// Login a customer
Kustomer.login({
  jwtToken: 'SOME_JWT_TOKEN'
});


// Login a customer and run a callback after the login
Kustomer.login({
  jwtToken: 'SOME_JWT_TOKEN'
}, function (loginCallbackResponse, error) {
  if (!error) {
    console.log('User was authenticated!');
  }
});
