The script link that needs to appear on every page is as follows:
<!-- Voiceable tag -->
If you are using Google Tag manager you can install the following custom tag as explained here:
<!-- Voiceable gtag -->
where YOUR_CLIENT_CODE is your custom indicator and will be provided to you by Voiceable.
In addition it is required to install a conversion tracker. This way the assistant can learn about successful journeys and provide more value to similar users in the future.
To install a conversion tracker please see following documentation:
1. Open Admin page of your Shopify.
2. Go to "Settings" (lower right corner) -> "Checkout"
3. Scroll to "Additional scripts" and add the script link as shown above
