restoreChat(options)

Description

Use this method to restore the chat widget after page reload/navigation.

Important
Currently, this method only works for "embedded" mode.

If the previous page was unloaded during the registration phase, restoreChat will try to restore the chat widget with the registration form.

Returned promise

restoreChat returns a "promise" object with two chainable methods: done and fail.

done

This method can be used to get access to chat session service API.

chat.restoreChat(options).done(function(session) {
  // session.sendMessage, session.onAgentConnected and all other methods are at your disposal.
});

See Chat Service JS API for documentation about using the session API. If you need to access Chat Session API, you will probably want to get the access not only in cases when session is restored, but also when it is started fresh. You can use startChat's "done" callback for this. See Getting access to Chat Session API for more info.

Important
The promise is not resolved before the chat session is created. This means that if the chat widget is restored during the registration phase (the registration form is displayed to the user), the done callback is not sent until the registration is complete and processed by server.

fail

If chat restoration fails because of an error (and not because the chat session does not exist), the fail callback receives an event argument with an error property, similar to the startChat().fail callback.

chat.restoreChat(options)
  .fail(function(event) {
    // If there was chat session, but restoration fails, signal failure.
    if (event.error) {
        alert('chat restoration failed');
        return;
    }
    // If there was no chat session, bind start chat to "start chat" button
    jQuery('#myChatButton').on('click', function() {
        chat.startChat(startChatOptions);
    }
  })
  .done(function(session) {
    // session.sendMessage, session.onAgentConnected and all other method are at your disposal.
  });
Tip
For a list of possible error codes, see Error Codes.

Options

Some chat states are restored automatically after page reload/navigation. However, most options must be passed to restoreChat directly. Supported options are:

  • embedded — Must be explictly passed as true. Otherwise an error occurs.
  • transport — Include if providing a custom transport.
  • registration — If you are using a custom function for registration and you want this registration to be restored, you must pass this option to both startChat and restoreChat.
  • ui — If you want to customize/disable the chat UI, pass this option to both startChat and restoreChat.
  • localization — For localization, pass the custom localization URL to both startChat and restoreChat.
  • debug — If you want logs enabled, you must pass this option to restoreChat explicitly.
  • logger
  • maxOfflineDuration
  • disableWebSockets
