Where the Data Goes
When a customer purchases through your link, the attribution data is saved as metafields on the Shopify order:
cl_utm_source,cl_utm_medium,cl_utm_campaign,cl_utm_term,cl_utm_contentcl_refcl_custom_*for each custom parametercl_shortcode— The link that made the sale
You can view these on individual orders in your Shopify admin, or access them from any tool that reads Shopify order metafields.
Use consistent naming conventions across all your links (always lowercase, use hyphens or underscores)
Set attribution before sharing — you can't retroactively tag past clicks
