Frequently asked questions

TagGap reads your Shopify orders and what Google Analytics 4 and Meta reported for the same period, matches them, and shows you which orders never arrived, which were counted twice and which were sent with the wrong value. Every finding comes with the evidence behind it and a step-by-step fix guide.

No. TagGap is read-only. It asks Shopify for read_orders only, Google for analytics.readonly and Meta for ads_read. It never edits your theme, pixels, Customer events, campaigns or ad accounts, so it cannot break anything that works today.

Server-side tracking apps (for example Elevar, Littledata, Stape or TAGGRS) send events to GA4 and Meta. TagGap checks whether those events actually arrived, order by order. Keep the tracking setup you have and use TagGap to prove it works, or to find out exactly where it does not.

The free scan looks at your public storefront from the outside: which pixels and tags load, which load twice and how consent is defaulted. Purchase tracking now runs inside Shopify checkout, where no outside scan can see it, so only the app, which reads your orders, can tell you which purchases went missing.

Order by order. The GA4 transaction_id is compared with the Shopify order id, order number and order name. If no id matches, TagGap looks for a single purchase with the same value in the same hour and labels that match as fuzzy. Orders that still have no purchase are listed as missing, with the ids it searched for.

Meta only exposes daily purchase totals to apps, so TagGap compares daily counts and revenue with your Shopify orders. On days with a gap it lists the orders that carried a Meta click or browser id as likely unreported. It labels them probable, not confirmed, because Meta does not reveal which individual purchases it received.

Test orders, cancelled orders, draft and B2B orders and subscription renewals are excluded, because most stores never send them as online purchases. That way a POS sale or a rebill is not reported as broken tracking.

Yes. Consent choices, ad blockers, attribution windows and time zones mean the numbers rarely match exactly. The problem is that a normal gap and broken tracking look the same in a dashboard. TagGap separates them: it shows which orders are missing and the likely reason, so you can tell expected loss from a tag that stopped firing.

The last 60 days of orders, which is what Shopify allows apps without the read_all_orders permission. TagGap deliberately does not request wider access.

Order ids and numbers, times, status, sales channel, payment gateway names, totals, landing page and attribution click ids, plus daily purchase totals and transaction ids from the platforms you connect. It does not request or store customer names, emails, phone numbers, addresses or IP addresses. Order data is deleted after 13 months, and all store data is deleted after you uninstall.
