BigCommerce - TikTok Events API

Send every BigCommerce event to the TikTok Events API, server-side

Q: Will I see duplicate conversions if I run both the TikTok Pixel and the Events API?

No, as long as the Pixel ID in Upstack matches the TikTok Pixel firing in your storefront. Upstack sends a shared event_id on every server-side event and TikTok keeps only one copy. If you see duplicates, the Pixel IDs almost always differ.

Q: Which events does the TikTok Events API receive?

PageView as Pageview, ViewContent as ViewContent, AddToCart as AddToCart, InitiateCheckout as InitiateCheckout and Purchase as Purchase.

Q: Which customer parameters are sent to the TikTok Events API?

Every event carries email, phone and external_id when available, hashed with SHA-256 as the Events API requires, plus the ttclid click ID captured by the Upstack Pixel for deterministic matching.

Q: How do I check that BigCommerce events are reaching the TikTok Events API?

Upstack marks the destination Healthy, and TikTok Events Manager shows events arriving via both Browser and Server (CAPI), with a test order’s Purchase event appearing within a few minutes. “Update Recommended” warnings in Events Manager are normal and need no action.

Q: How long does it take to connect BigCommerce to the TikTok Events API?

Most brands are live in under 20 minutes. Once BigCommerce is connected, every destination receives the same resolved events, the TikTok Events API included.

Each event is resolved to a person against a 750M+ device graph before it reaches the TikTok Events API, with restored click IDs, deduplicated conversions and delivery you can audit.

How it flows

How a BigCommerce event reaches the TikTok Events API. Captured on the server, resolved to a person, then sent.

01 Capture

Captured from BigCommerce

Server-side capture of BigCommerce storefront and checkout events, resolved and forwarded downstream.

02 Understand

Resolved to one person before it leaves

Every BigCommerce event is matched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer rather than two strangers.

How resolution works

Resolved before it is sent

IdentityMatched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer.
customer_typeNew or returning, resolved before send.
DeduplicationBrowser and server copies of the same purchase collapse on event ID, so nothing is counted twice.
Bot and fraud filteringAutomated traffic never reaches the model, because what you keep out of the training set matters as much as what goes in.

Ad platforms accept almost anything and tell you very little. These controls exist so you can see what was sent and what was accepted, rather than inferring it from a reporting gap.

03 Activate

Which events reach the TikTok Events API

Each Upstack event is mapped to the TikTok Events API event below before it is sent.

Upstack event	Sent to TikTok Events API as	Key data on the event
Page view	Pageview	url, referrer
Product view	ViewContent	content_id, content_type, value, currency
Add to cart	AddToCart	content_id, content_type, value, currency
Checkout	InitiateCheckout	value, currency, quantity
Purchase	Purchase	content_id, value, currency, order_id

Every event carries email, phone and external_id when available, hashed with SHA-256 as the Events API requires, plus the ttclid click ID captured by the Upstack Pixel for deterministic matching.

The catch

BigCommerce's hosted checkout limits what a browser tag can see at the moment of purchase, which is exactly the moment that matters for conversion tracking.

What changes

What changes when BigCommerce feeds the TikTok Events API. Two gains on the TikTok Events API side, two on the BigCommerce side.

TikTok Events API

Server-side delivery

By default Upstack sends events to TikTok from its servers as well as through the TikTok tag, so an event an ad blocker or browser privacy setting stops in the browser still arrives from the server.

TikTok Events API

Identity-resolved events

Events sent to TikTok carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.

BigCommerce

Every event, server-side

Storefront and checkout events are captured from BigCommerce on the server, independent of the browser.
