  }

  const btn = document.getElementById('btn');

  // set listener to button to trigger `onClick` function
  btn.addEventListener('click', onClick)

  document.addEventListener("DOMContentLoaded", function () {

# Steps configuration

Wait for Chat Process Global Command
Wait for chat configuration Process global command configuration

Process global command configuration

After click on button SDK will trigger global command and send message to the chat.

# Passing custom data when triggering global command

sendGlobalCommand method in SDK has data parameter that allows to provide any data that will be passed to Process Global Command (RWC) step merge field.

# Example

SDK.sendGlobalCommand({
  name: 'globalComamndName',
  data: { someData: 'some text' }
});

// or

SDK.sendGlobalCommand({
  name: 'globalComamndName',
  data: 'just text'
});

# End session in embed chat from Custom Request Response or inner SDK

To end current session and close embed chat:

# Example

SDK.endSession();

// or in Custom Template

window.SDK.endSession();

# Accesing SDK in JavaScript fields

When writing JavaScript code in Custom template input component or customizing header/footer you can access SDK via RWC global JavaScript variable.

# Example:

// some JS logic
// ...

RWC.on('receive-message', function (message) {
  console.log('new message ->', message)
});

// ...
