It's important that the on-site widget is set up even if you do not want it visible on your site as all the other widgets require the on-site widget code to be in place in order to work.
During the installation/signup process, a code snippet is given to you to place on your site. This code snippet should be placed within your head tag (<head></head>) in the HTML file of all the pages on your site.
If you happen to have mistakenly skipped this, no worries. Follow the steps below to get access to the code again.
1. Login to your dashboard and click on Customize Widgets from the menu panel on the left.
2. At the top of the page, there's a piece of instruction. Click on the link "Click here". This will expose the on-site widget code. Copy the code and place it within your head tag (<head></head>) in the HTML file of all the pages on your site.
3. If you've placed the code successfully in the HTML files, refer to this guide on how to customize the widget to suit your brand.
