Refersion connection for Shopify
Track Refersion affiliate sales in Google Analytics, next to every other marketing channel
The direct answer
How does Littledata track Refersion affiliates in GA4?
Refersion tags affiliate links with the source "refersion". Littledata's server-side Shopify tracking reads that tag and attributes each resulting order in Google Analytics 4, so you see affiliate revenue, checkout steps, and refunds alongside search, paid social, and email. Refersion's dashboard still shows which affiliate earned each order; GA4 shows how affiliates contribute to conversion across channels.
- Affiliate revenue in GA4 - orders from Refersion links, attributed server-side.
- Sales by affiliate - when Refersion sends the affiliate ID as the campaign or medium.
- Discount codes tracked - coupon codes linked to orders and marketing channels.
- Multi-channel view - see when affiliates bring new visitors that another channel converts.
What does Refersion send to GA4?
The source is always refersion. The medium depends on your Refersion configuration.
| UTM parameter | Value | Where to find it in GA4 |
|---|---|---|
| Source | refersion | Session source in Traffic acquisition |
| Medium | affiliate, influencers, or the affiliate ID | Session source/medium |
| Campaign | Affiliate ID, if Refersion is set up to send it | Session campaign, to split sales by affiliate |
The problem
Why affiliate sales are hard to see in Google Analytics
Shopify's built-in Google Analytics tracking has well-known gaps in attributing sales to marketing campaigns, and affiliate traffic is no exception.
- Missing orders - browser tags miss purchases when ad blockers or closed tabs stop the purchase event.
- Lost affiliate credit - when the order isn't linked to the session from the affiliate link, GA4 credits it to Direct.
Littledata captures every order server-side and stitches it to the original session, so affiliate traffic gets the credit it earned in GA4.
