I have a code from LinkedIn for an event-specific pixel to track a purchase when there is no unique URL and instead the customer clicks on a button. I do not know where to enter this code in shopify backend. Can someone help?
Here is an example fo this code
<img height="1" width="1" style="display:none;" alt="" src="https://px.ads.linkedin.com/collect/?pid=2890777&conversionId=3444129&fmt=gif" />
