The problem

Pinterest is reporting on incomplete data

Pinterest Ads rely on browser-side tracking that's increasingly unreliable. Ad blockers, iOS App Tracking Transparency, and consent banners reduce event delivery — and underreport conversions, making Pinterest look weaker than it actually is.

  • Pinterest Tag misses a significant portion of conversions due to ad blockers and browser restrictions
  • Underreported conversions make Pinterest look less effective than it actually is
  • Budget gets shifted away from Pinterest based on incomplete attribution data

How TrackBee fixes it

Your Shopify data, delivered to Pinterest

Three layers that work together so Pinterest gets a complete, clean signal — without you touching tag code.

Pinterest Conversions API

TrackBee sends conversion events directly from Shopify's servers to Pinterest's Conversions API — so browser restrictions don't drop your data. Reliable, complete event delivery.

Enhanced match quality

Hashed customer identifiers (email, phone, IP) are sent with every event, allowing Pinterest to accurately attribute conversions to the right ad interactions.

Prove Pinterest's real value

With complete conversion data, you can finally see Pinterest's true ROAS. No more underreporting that causes budget to shift away from a profitable channel.

Exclusive feature

Separate new vs. returning customer events in Pinterest

TrackBee sends two custom events to Pinterest's Conversions API: NewCustomerPurchase and ReturningCustomerPurchase. Build acquisition audiences and retention audiences separately — without manual setup.

NewCustomerPurchase

Fires when a first-time buyer completes a purchase. Use it to build prospecting audiences and lookalikes from real new customers — and prove Pinterest's value as an acquisition channel.

ReturningCustomerPurchase

Fires when an existing customer makes another purchase. Use it for retention campaigns and to measure repeat-buyer behaviour separately from new customer acquisition.

How to enable it

  1. 1 Open your TrackBee dashboard and select your store
  2. 2 Go to your Pinterest integration settings
  3. 3 Toggle on the "New vs Returning" feature
  4. 4 The custom events appear in Pinterest after the next purchase
  5. 5 Build separate audiences and reporting columns around each event
Note: The NewCustomerPurchase and ReturningCustomerPurchase events only show up in Pinterest after a purchase has been processed. If you don't see them yet, wait for the next order to come in.

FAQ

Common questions about Pinterest Ads + TrackBee

TrackBee uses Pinterest's Conversions API to send conversion data directly from your Shopify servers. This server-to-server connection works independently of browser restrictions, ad blockers, and consent limitations that affect the Pinterest Tag.

No. You can keep the Pinterest Tag running alongside TrackBee's server-side tracking. Pinterest automatically deduplicates events using unique event IDs, so there's no risk of double counting. Most merchants keep both for maximum coverage.

TrackBee sends all key Pinterest events including PageVisit, AddToCart, Checkout, and Purchase. Each event is enriched with hashed first-party customer data and product information, giving Pinterest's algorithm the best possible optimisation signals.

No. Each event TrackBee sends includes a unique event ID. If both the Pinterest Tag and TrackBee report the same conversion, Pinterest deduplicates them automatically. You get full coverage without inflated numbers.

Yes. TrackBee uses your Shopify customer history to tag every purchase as new or returning, and sends separate NewCustomerPurchase and ReturningCustomerPurchase events to Pinterest. You can then build acquisition vs. retention audiences and report on them independently.
