Get Started
Get Clerk up and running on your Lightspeed store in just a few steps. This guide walks you through connecting your store, installing tracking scripts, and syncing your data.
Connecting your store #
After following these simple steps you will be able to see your Live Demo, which gives you a personal overview of how Clerk will work on your webshop, before setting up the rest of the system.
Add store #
After logging in to my.clerk.io, the first thing you need to do is add your store:

Write the Name and Domain of your webshop.
Choose Lightspeed as the Platform and choose your Currency.
Click Add Store.
Install tracking scripts #
In your Lightspeed backend, go to Settings > Website-Settings > Web Extras.
Visitor tracking: Find the Custom JS box and insert the Clerk visitor tracking script.
- Replace INSERT_PUBLIC_API_KEY with your Public Key from my.clerk.io > Developers > API Keys.
- If this doesn’t work, insert the script in the Tracking box instead.
<!-- Clerk.io Visitor Tracking (Lightspeed) -->
<script type="text/javascript">
(function(w,d){
var e=d.createElement('script'); e.type='text/javascript'; e.async=true;
e.src='https://cdn.clerk.io/clerk.js';
var s=d.getElementsByTagName('script')[0]; s.parentNode.insertBefore(e,s);
w.__clerk_q=w.__clerk_q||[]; w.Clerk=w.Clerk||function(){w.__clerk_q.push(arguments)};
})(window,document);
Clerk('config', {
key: 'INSERT_PUBLIC_API_KEY',
formatters: {
convert_currency: function(price) {
const rate_raw = '{{ 100 | money }}'.replace(/[^0-9.]/g, '');
const rate = parseFloat(rate_raw) ? (parseFloat(rate_raw) / 100) : 1;
return rate * price;
}
},
globals: {
currency_iso: '{{ shop.currency2.code }}',
currency_symbol: '{{ shop.currency2.symbol }}'
}
});
{% if page.account.email %}
Clerk('call', 'log/email', { email: '{{ page.account.email }}' });
{% endif %}
</script>
- Order tracking: In the same page, find the Tracking box and insert the Clerk order tracking code below the visitor script.
<span
class="clerk"
data-api="log/sale"
data-sale="{{ order.information.number }}"
data-email="{{ order.customer.email }}"
data-customer="{{ order.customer.id }}"
data-products='[{% for product in order.products %}{"id":{{ product.product_id }},"quantity":{{ product.quantity }},"price":{{ product.base_price_incl }}}{% if not loop.last %},{% endif %}{% endfor %}]'>
</span>
- Click Save.
Sync data #
Go to my.clerk.io > Data > Configuration.
Enter the following information for your Lightspeed store:
Domain: Your webshop URL (for example, https://www.beautifulshop.nl/).

Insert the details into the importer fields. Optional advanced settings can be left as they are.
