Botframework v4 Directline integration: Is there a way to get the conversation id generated from directline transfer to the Chatbot (nodejs code)

Question

This might be very simple, but I cannot find any reference regarding this. I integrated the chat bot in the web app using direct line API; I’m using this API to generate conversation id:

POST: https://directline.botframework.com/v3/directline/conversations

I’m trying to get the generated conversation id from the above API (from web app code) to the chatbot code (NodeJS). Is there a way or any reference to do this?

I resolve it using Botframework Web Chat back channel, here's the link for reference: https://github.com/Microsoft/BotFramework-WebChat

After I generated the conversation id using directline API: POST: https://directline.botframework.com/v3/directline/conversations

I send data from the web app to the chatbot via backchannel.

<div id="webchat"></div>
<script>
  (async function () {
    // We are using a customized store to add hooks to connect event
    const store = window.WebChat.createStore({}, ({ dispatch }) => next => action => {
      if (action.type === 'DIRECT_LINE/CONNECT_FULFILLED') {
        // When we receive DIRECT_LINE/CONNECT_FULFILLED action, we will send an event activity using WEB_CHAT/SEND_EVENT
        dispatch({
          type: 'WEB_CHAT/SEND_EVENT',
          payload: {
            name: 'webchat/join',
            value: { conversation_id: conversationID }
          }
        });
      }

      return next(action);
    });

    window.WebChat.renderWebChat({
      directLine: window.WebChat.createDirectLine({ token }),
      store
    }, document.getElementById('webchat'));

    document.querySelector('#webchat > *').focus();
  })().catch(err => console.error(err));

  //Note: conversationID and token is generated in the backend code of the web app.
</script>
