How it flows
How a Loop Subscriptions event reaches the TikTok Events API. Captured on the server, resolved to a person, then sent.
01 Capture
Captured from Loop Subscriptions
Capture Loop Subscriptions events server-side (new subscriptions, renewals, swaps and cancellations), each as what it actually is.

02 Understand
Resolved to one person before it leaves
Every Loop Subscriptions event is matched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer rather than two strangers.

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
Swaps, pauses and saves produce state changes with no order attached.
Ad platforms receiving only orders see a paused subscriber as churned and start bidding to re-acquire someone who is still a customer.

What changes
What changes when Loop Subscriptions feeds the TikTok Events API. Two gains on the TikTok Events API side, two on the Loop Subscriptions 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.
Loop Subscriptions
Every event, server-side
Storefront and checkout events are captured from Loop Subscriptions on the server, independent of the browser.

Under Destinations, add TikTok with your Pixel ID (a 20 character alphanumeric string, also called the Dataset ID) and an Events API access token generated in TikTok Events Manager, which is shown only once.
-
03
Check Browser and Server events
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.
FAQ
Questions about Loop Subscriptions and the TikTok Events API.
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.
Which events does the TikTok Events API receive?
PageView as Pageview, ViewContent as ViewContent, AddToCart as AddToCart, InitiateCheckout as InitiateCheckout and Purchase as Purchase.
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.
How do I check that Loop Subscriptions 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.
How long does it take to connect Loop Subscriptions to the TikTok Events API?
Most brands are live in under 20 minutes. Once Loop Subscriptions is connected, every destination receives the same resolved events, the TikTok Events API included.
