Choose whether to load the Reddit Pixel

Tracking Method is set to Browser + Server by default, which loads the Reddit Pixel on your storefront alongside Upstack’s own server-side delivery. Keep Browser + Server unless you already load the Reddit Pixel yourself through Google Tag Manager, your theme, or another app — in that case, switch the Tracking Method to Server and see Server-Only Destinations.Unchecking it does not stop Upstack tracking. The Upstack Pixel keeps capturing events and forwarding them through the Conversions API. See Server-Only Destinations.

Enter your Pixel ID and CAPI token

Fill in the form:
  1. Reddit Pixel ID — the identifier for your Reddit pixel. Reddit Pixel IDs are typically prefixed with t2_ (e.g., t2_abc123def).
  2. Conversions API access token — a secure key generated from Reddit Ads Manager Events Manager.
The Conversions API token is a non-expiring secure key. Store it securely and never expose it client-side. If the token is compromised, generate a new one and follow the update CAPI token guide.
