New to Upstack? Follow the getting started guide for a streamlined onboarding walkthrough.
  • Configure the Reddit destination in Upstack Data with your Pixel ID and Conversions API access token.

​
Prerequisites

Before you start, you need:
1

Configure the Reddit destination in Upstack Data

In the Upstack dashboard, navigate to Destinations and add a Reddit destination using your Pixel ID (typically prefixed with t2_) and Conversions API access token.Help guide:How to configure the Reddit destination in Upstack Data →
2

Remove duplicate Reddit pixel installations

Reddit does not have a native Shopify sales channel like Meta or TikTok, but many brands install the Reddit pixel manually via theme.liquid, Customer Events, or third-party apps. Multiple active pixels with the same Pixel ID cause inflated metrics that Reddit cannot deduplicate without a shared conversion_id.
Help guide:How to remove duplicate Reddit pixel installations in Shopify →Common installation locations to check:
  • Shopify Settings → Customer Events for any custom Reddit pixel scripts
  • Theme files (theme.liquid, header snippets) for hardcoded rdt('init') calls
  • Third-party Reddit pixel apps in Shopify
  • Reddit pixel tags inside Google Tag Manager

Verify the full setup is healthy

Confirm each piece of the setup is working:
  • In the Upstack dashboard, Destinations shows your Reddit destination as Healthy (green).
  • In Reddit Ads Manager Events Manager, the pixel shows recent events with a Server badge for CAPI events.
  • The Event Match Quality (EMQ) column in Reddit’s Events Manager shows a score for each event type.
If anything is unhealthy, check the corresponding help guide above for troubleshooting steps.

​
What to expect after setup

​
Event Match Quality timeline

  • Event Match Quality (EMQ) scores update gradually as Reddit receives server-side events with stronger match keys.
  • Tracked conversions typically increase compared with the browser pixel alone, since CAPI captures conversions lost to ad blockers and iOS restrictions.
  • The Purchase EMQ score sees the biggest improvement because checkout-time events carry the strongest match keys (hashed email, phone, address).

​
Reporting differences

  • Your Reddit Ads Manager ROAS can change as Reddit attributes more conversions to ads.
  • Conversion volume may temporarily fluctuate during the first 48 hours as Reddit’s deduplication logic adjusts to receiving both pixel and CAPI events.
