BigCommerce - Reddit

Send every BigCommerce event to Reddit, server-side

Q: Will my events be counted twice if I run both the Pixel and CAPI?

No. Upstack sends a shared conversion_id on every server-side event, and Reddit deduplicates against the matching browser Pixel event. As long as the Pixel ID in Upstack matches the Pixel ID firing in your storefront, deduplication is automatic.

Q: Which events does Reddit receive?

PageView as PageVisit, ViewContent as ViewContent, AddToCart as AddToCart, InitiateCheckout as InitiateCheckout (custom event server-side) and Purchase as Purchase.

Q: Which customer parameters are sent to Reddit?

Every event carries every available match key: hashed email and phone, external_id, the rdt_cid click ID, user agent and IP address. Personal data is hashed with SHA-256 before it leaves Upstack.

Q: How do I check that BigCommerce events are reaching Reddit?

Upstack marks the destination Healthy, and Events Manager in Reddit Ads Manager shows recent events with a Server badge for CAPI events and an EMQ score for each event type. Conversion volume may fluctuate during the first 48 hours while Reddit’s deduplication adjusts.

Q: How long does it take to connect BigCommerce to Reddit?

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

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

How it flows

How a BigCommerce event reaches Reddit. 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

Delivered to Reddit

Forward resolved conversions to the Reddit Conversions API, so a platform where the click and the purchase are often days apart still gets credited.

Which events reach Reddit

Each Upstack event is mapped to the Reddit event below before it is sent.

Upstack event	Sent to Reddit as	Key data on the event
Page view	PageVisit	URL, referrer, user agent
Product view	ViewContent	products, value, currency
Add to cart	AddToCart	products, value, currency
Checkout	InitiateCheckout (custom event server-side)	value, currency, itemCount
Purchase	Purchase	value, currency, transactionId, products

Every event carries every available match key: hashed email and phone, external_id, the rdt_cid click ID, user agent and IP address. Personal data is hashed with SHA-256 before it leaves Upstack.

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.

Where to check in RedditDelivery you can audit

Reddit Ads Events Manager Conversions API

Server events appear with a Conversions API source label, and the events table shows which parameters arrived.

What changes

What changes when BigCommerce feeds Reddit. Two gains on the Reddit side, two on the BigCommerce side.

Server-side delivery

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

Identity-resolved events

Events sent to Reddit 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.
