The mechanism
Littledata adds a data layer and webhooks to your Shopify store, captures every event once, and relays it simultaneously to each connected platform through its native API - the same purchase values and identifiers everywhere, with no per-platform pixels. Connect once, then enable channels as needed - a new destination never means rebuilding your tracking.
Email, phone, name, and address are hashed and attached to every conversion for privacy-safe matching.
gclid, fbp/fbc, ttp/ttclid, and _epik are captured when the shopper lands and joined to the purchase, so each platform attributes the sale to its own ad.
Every event carries the market handle and ID, for regional reporting and market-specific audiences.
Conversions fire from Shopify's order system server-side, unaffected by ad blockers, iOS privacy restrictions, or cookie limitations.

The data layer
The data layer aligns automatically with Shopify's release cycle, so your tracking never breaks when Shopify changes - no manual tag patches, no engineering time, no GTM upkeep.
Add Littledata from the Shopify App Store - no code and no developer needed, and nothing loads on your checkout pages.
Sign in to each platform from the Littledata dashboard. Each connection goes live in about 10 minutes.
Littledata's conversions run alongside your existing tracking, so you can validate the uplift on each platform before making them primary.
The Google & YouTube, Facebook & Instagram, TikTok, and Microsoft Channel apps each connect a single platform - and miss the signals that power optimization.
Each app connects a single ad platform, with its own setup, settings, and quirks to maintain.
Client-side tracking loses conversions to ad blockers and iOS privacy restrictions, and mid-funnel events never fire server-side.
No new vs returning customer split, and no control over which conversions the algorithm optimizes for.
Hashed first-party data powers Enhanced Conversions in Google and Microsoft, and lifts Meta's Event Match Quality score from 7 to 9.
Purchases, subscriptions, and post-purchase upsells fire from Shopify's servers, plus cart and checkout events where each platform's API supports them.
New vs returning customer conversions, net revenue with Profit Signal, and custom events built in the Event Editor.
