Add the Confirmation page function

When a customer completes their purchase, you can send their order and product information to Affirm for A/B testing, which will help you optimize your site. Send this information by adding the Confirmation Page function to your payment confirmation page. We only require orderId, total, productId, and quantity for A/B testing.

Click here for all the Confirmation Page function parameters.

To add the confirmation page function, go to Settings > Checkout > Order Processing > Additional scripts and add the code below. Replace public_api_key with your public API key found in the merchant dashboard.

<script>
_affirm_config = {
   public_api_key:  "YOUR_PUBLIC_KEY",
   script:          "https://cdn1.affirm.com/js/v2/affirm.js"
};
(function(l,g,m,e,a,f,b){var d,c=l[m]||{},h=document.createElement(f),n=document.getElementsByTagName(f)[0],k=function(a,b,c){return function(){a[b]._.push([c,arguments])}};c[e]=k(c,e,"set");d=c[e];c[a]={};c[a]._=[];d._=[];c[a][b]=k(c,a,b);a=0;for(b="set add save post open empty reset on off trigger ready setProduct".split(" ");a<b.length;a++)d[b[a]]=k(c,e,b[a]);a=0;for(b=["get","token","url","items"];a<b.length;a++)d[b[a]]=function(){};h.async=!0;h.src=g[f];n.parentNode.insertBefore(h,n);delete g[f];d(g);l[m]=c})(window,_affirm_config,"affirm","checkout","ui","script","ready");
 
affirm.ui.ready(function(){
affirm.analytics.trackOrderConfirmed({
    "orderId": "{{ order.id }}",
    "total": "{{ order.total_price }}"
}, [{
   {% for item in order.line_items %}
   "productId": "{{ item.sku }}",
   "quantity": "{{ item.quantity }}",
   {% endfor %}
}]);
});
