In some cases we might want to trigger events or pass values from the bot to the parent site where a Landbot is embedded. Maybe we need to change the design of the page, to show the progress, or to trigger other actions.

In this example we will show how to trigger a redirection to a call, but the same principle works for other cases like a progress bar for example

Change the phone number according to your needs.

  1. In the site where the bot is embedded you need to add the following code (it will trigger the redirection):

myLandbot.on('sendto',(data) => { 
window.location.href = data;

How did we do?
