How to reconcile Pinterest Ads against your store's order table
This is the check we run first on every account, written out so you can run it without us. It takes about thirty minutes and needs two numbers: what Pinterest says it produced, and what your store's order table actually shows. The gap between them is the only honest measure of whether your tracking works — and if it comes back small, you do not need us.

Pinterest checkouts vs your orders: separate click from save
Save epik on each order and send the order ID as the event_id on the tag and Conversions API checkout event. Compare click-attributed checkouts for a closed month against paid online orders carrying epik. Pinterest's engagement and view conversions sit on top of that; a shortfall from late save-then-buy orders is normal, a total above all online orders is not.
Pinterest reports totals, so the working join is the set of orders whose visit carried epik. Read it from the landing URL, which on shopping ads is often a product page rather than your homepage, and write it to the order. The tag's purchase event is the checkout event; send your order ID as its event_id from both the tag and the server so one order is not counted twice.
Pinterest splits conversions into click, engagement and view paths, each with its own window set per campaign. An engagement conversion can be someone who saved a Pin and bought days later without clicking. Compare click-attributed checkouts with your epik-carrying orders, and treat the other paths as a separate claim. Check whether your report places conversions on the date of the ad action or the conversion, because with long windows last month's figure keeps growing after it closes.
Use the conversion reporting in Ads Manager with the click, engagement and view figures shown separately. Pinterest below your epik-carrying orders is common: Pins saved weeks earlier fall outside the click window even though they started the sale. The usual cause of disagreement in this pair is comparing Pinterest's combined total, inflated by engagement and view paths, against orders, or checkout events arriving with no value attached.
Pinterest × Ecommerce Orders · what breaks
Why Pinterest and your store's order table disagree
- 01
Refunds never subtracted
The most common cause and the easiest to check. Sum refunds for the same period — if the platform figure is roughly your gross and your own figure is net, that difference is the whole gap.
- 02
Purchase event firing on page refresh
A confirmation page that re-fires on reload counts one order several times. Compare distinct order IDs against total conversions.
- 03
Point-of-sale orders in the same table
If you have a physical shop, counter sales sit in the same order table and will be counted as advertising conversions unless the channel is filtered.
- 04
Post-purchase upsells arriving late
If the conversion fires at checkout and an upsell adds revenue afterwards, the platform is under-reporting by the upsell take rate.

What each side is actually counting — Pinterest × Ecommerce Orders
- 1
What Pinterest counts
An event name Pinterest recognizes, an event_id matched to the tag, a timestamp, hashed customer information, and the click identifier where you have it. Read the delivered and matched counts in Pinterest's reporting rather than assuming a 200 response means the event landed usefully.
- 2
How Pinterest attributes it
Pinterest appends epik to your landing page URL and the tag stores it in the _epik cookie. It is a single parameter rather than Google's three, which makes capture simpler — but Pinterest traffic skews heavily to iOS and to saved Pins opened weeks after they were first seen, so the identifier frequently arrives on a visit that is nowhere near the conversion. Persist it server-side the moment you see it.
- 3
The window it uses
Pinterest's attribution windows are configurable per campaign and separate the click path from the engagement and view paths, which is unusual. Confirm which window your reporting is set to before comparing anything, and verify the accepted event-freshness limit for server events against Pinterest's current documentation.
- 4
What your store's order table counts
Paid orders with their totals, found in Shopify Admin → Orders, WooCommerce → Orders, or a direct query against the orders table.
- 5
The filter that makes them comparable
Financial status is paid, and the sales channel is online rather than point of sale.

Reading the gap — Pinterest × Ecommerce Orders
| What you see | What it usually means |
|---|---|
| 15%+ platform higher | Usually the wrong event entirely — the platform is claiming more than you took. usually refunds, duplicate firing, or a second channel bleeding into the same conversion action. |
| 20%+ platform lower | Usually structural — the platform is seeing fewer orders than you actually took. usually consent, ad blocking, or an identifier that never reached the order. |

Read the event delivery and match reporting inside Pinterest Ads Manager, not the API response code
Pinterest is a save-now-buy-later platform in a way the other networks are not. A Pin saved in October and acted on in December is normal behavior, and it sits far outside any sensible click window — so a share of genuine Pinterest-driven revenue is structurally unattributable no matter how good the build is. Say that out loud before anyone sets a target.

Pinterest × Ecommerce Orders · when not to buy
When the answer is that you do not need us — Pinterest × Ecommerce Orders
- If almost all of your orders come from a channel with no click behind it, no tracking work will reach them — and knowing that is worth more than a build.
- If Pinterest is a small test line on your media plan, the Conversions API is more work than the signal is worth this quarter. It earns its keep when Pinterest is a channel you are actually scaling.

FAQ
Pinterest × Ecommerce Orders questions, answered
Not in the main comparison. Reconcile click-attributed checkouts against orders carrying epik, and report engagement and view conversions as Pinterest's additional claim.
When conversions are dated by the ad action, late orders from long windows are added to the month of the original click. Wait for the window to close before comparing.
Because you should know the size of the problem before anyone quotes you for it. If the gap is small, you have saved yourself a purchase. If it is large, you now know what you are buying rather than taking our word for it.
No. Both numbers come from systems you already own and neither leaves them. There is no tool to sign up for and nothing to upload.
Then compare totals for a closed period and treat the result as directional rather than exact. The event delivery and match reporting inside pinterest ads manager, not the api response code is still the right place to read the platform's side.
Under five percent is working. Five to fifteen usually means reversals are missing. Above twenty is normally the wrong event being counted, not a broken tag — which is why debugging tags first wastes so much time.
Then fix the filter before drawing any conclusion. Financial status is paid, and the sales channel is online rather than point of sale. A mismatch in scope produces a gap that looks like a tracking fault and is not one.
