  • Reddit does not have a native Shopify sales channel like Meta or TikTok — Reddit pixels on Shopify are typically installed manually.
  • If multiple Reddit pixels with the same ID are firing, conversions get counted more than once.
  • Consolidate to a single browser pixel installation, then let Upstack handle server-side delivery via CAPI.
  • Reddit deduplicates the browser pixel and CAPI events automatically using the shared conversion_id.
Why this mattersUnlike Meta or TikTok, Shopify does not have a native Reddit sales channel pixel. Brands typically install the Reddit pixel via Shopify Customer Events, theme.liquid edits, third-party apps, or Google Tag Manager. When multiple Reddit pixels with the same Pixel ID are firing on the same page, Reddit cannot deduplicate them without a shared conversion_id, which results in inflated conversion counts and degraded campaign optimization.Once you activate Upstack’s Reddit destination, the Upstack Pixel handles browser-side capture and forwards a deduplicated server-side event to Reddit CAPI. Any additional Reddit pixel installations on the same store should be removed.

​
Prerequisites

Before you start, you need:
  • Shopify owner or staff access with Customize Theme and Customer Events permissions
  • A list of all your existing Reddit pixel installations (theme code, apps, GTM tags)
  • Your Reddit Pixel ID — see How to find your Reddit Pixel ID

​
Common locations to check

Reddit pixels can be installed in any of these places. Check each one:
LocationHow to access
Shopify Customer EventsSettings → Customer Events in Shopify admin
Theme filesOnline Store → Themes → Edit Code — look in theme.liquid and header snippets
Third-party appsApps in Shopify admin — search for “Reddit”
Google Tag ManagerGTM workspace → Tags — filter by “Reddit”
Checkout extension scriptsPlus stores: Settings → Checkout → Order status page additional scripts

Steps to remove duplicate Reddit pixels

1

Inventory all current Reddit pixel installations

Before removing anything, document every place a Reddit pixel is firing:
  1. Customer Events: Go to Shopify admin → Settings → Customer Events and check for any custom pixels referencing rdt( or reddit.
  2. Theme code: Open Online Store → Themes → Edit Code and search the entire theme for rdt( or redditstatic.
  3. Apps: Look for any Reddit-branded apps under Apps in the Shopify admin.
  4. GTM: If you use Google Tag Manager, search for tags with names containing “Reddit” or scripts referencing the Reddit pixel.
Make a list of every location and the Pixel ID each one references.
2

Identify the canonical Reddit pixel

Decide which single Reddit pixel installation will remain. Recommended order of preference:
  1. Shopify Customer Events — most reliable, fires on checkout pages, easiest to maintain.
  2. Theme.liquid — works for older themes that don’t support Customer Events.
  3. Third-party app — only if the app provides functionality you need beyond pixel firing.
All other installations will be removed in the next steps.

Remove duplicate Customer Event pixels

In Shopify admin, go to Settings → Customer Events.For each Reddit-related custom pixel that is not your canonical installation:
  1. Click the pixel to open its details.
  2. Click Disconnect or Delete in the top-right.
  3. Confirm the action.
Disconnecting a custom pixel stops it from firing immediately. There is no undo, so confirm you have a backup of the script if you may need it later.
4

Remove Reddit pixel code from theme files

Open Online Store → Themes → Edit Code and search the theme for rdt( and redditstatic.For any matches that are not your canonical installation:
  1. Open the file containing the code.
  2. Delete the Reddit pixel script block (typically wrapped in <script> tags).
  3. Save the file.
Common files to check: theme.liquid, layout/theme.liquid, snippets/header.liquid, snippets/google-analytics.liquid.
5

Uninstall duplicate Reddit pixel apps

Go to Apps in the Shopify admin and locate any Reddit pixel apps that are not your canonical installation.Click Delete to uninstall the app. Confirm by reviewing app data deletion in the popup.
6

Remove duplicate GTM Reddit tags

If you use Google Tag Manager, sign in to your workspace and navigate to Tags.Filter for “Reddit” or search for tags referencing redditstatic.com or rdt(.For each tag that duplicates your canonical pixel:
  1. Click the tag to open it.
  2. Click the trash icon (top-right) to delete it.
  3. Submit and Publish a new GTM workspace version to deploy the change.
7

Verify only one Reddit pixel is firing

Open your storefront in a new browser tab with the Reddit Pixel Helper Chrome extension installed (search “Reddit Pixel Helper” in the Chrome Web Store).Navigate through your store: home page, product page, add-to-cart, and checkout.The Pixel Helper should show exactly one pixel firing per event. If you see duplicates, return to the previous steps and remove the additional installation.
8

Activate Upstack's Reddit destination

Once duplicates are removed, your single browser pixel and Upstack’s CAPI integration will work together cleanly. Reddit will deduplicate using the shared conversion_id.Confirm the Upstack Reddit destination is Healthy in your dashboard. See How to configure the Reddit destination if it isn’t already set up.
What if I want Upstack to be the only Reddit data source?You can also remove all browser-side Reddit pixel installations and let Upstack handle 100% of Reddit tracking server-side. This works, but you’ll lose real-time pixel signal in Reddit’s Events Manager. The recommended setup is to keep one browser pixel and let Upstack add the CAPI layer on top.
