One event id everywhere
On a purchase the id is your order id, so a reloaded thank-you page and the server event carry the same id and count once. Other events get a fresh random id: send that same id with the server event.
Ecommerce event code generator
Pick the event, add the products, and copy code for Google Tag Manager or gtag, the Meta Pixel and the TikTok Pixel. Every block uses the same event id, which is what lets each platform merge the browser copy with the server copy.

How it works
Clear the old ecommerce object
The GA4 block pushes { ecommerce: null } first. Without it, Google Tag Manager can merge the previous event's items into this one.
Exact totals
Value is price × quantity added up in whole poisha or cents, so prices like 0.10 never turn into 0.30000000000000004.
Questions
Platform rules from Google Analytics: Measure ecommerce, Meta: Handling duplicate Pixel and Conversions API events.
Which TikTok event is a purchase?
CompletePayment is TikTok's standard event for a completed payment, and the one this generator uses.
Do I need this with Trakero?
No. The Trakero WooCommerce plugin and Shopify app send these events with matching ids for you. The generator is for custom sites and for checking an existing setup.
Let Trakero do this for every order
Trakero captures click ids, hashes customer data and sends each purchase once to Meta, TikTok, GA4 and more from your server, so ad blockers and Safari can't lose it.
