Reddit Pixel Conversions API Addon for Google Analytics 4 PRO User Guide

Reddit Pixel Conversions API Addon for Google Analytics 4 PRO

Requires the Google Analytics 4 PRO extension.

Redefining Advertising: Reddit Pixel Conversions API.

What is Reddit's Conversions API?

Reddit's Conversions API (CAPI) acts as a method of securely sharing marketing data with Reddit via a server-to-server implementation, with the added benefit of not requiring website code.

With Conversions API (CAPI), advertisers can strengthen campaign performance by improving measurement accuracy, audience targeting and, subsequently, ad optimization. This is all done through a secure and sustainable server-side connection, resilient to signal loss and other obstacles that traditional, client-side implementations face.

What are the advantages of using Reddit's Conversions API?

Stronger campaign performance.
Improved measurement.
Better user targeting.
Increased accuracy for better ad optimization.

How does it work?

Here's a handy diagram to show you how the Reddit Pixel and Reddit Pixel Conversions API work:

How to configure the Reddit Pixel Conversions API Addon.

Enable Reddit Pixel Server Side Tracking - When enabled, the server side Reddit Pixel functionality will use the Reddit Pixel Javascript Tracking code you configured in the client-side Reddit Pixel configuration section.
Reddit Pixel ID - This ID can be found in your Reddit Ads Manager account under Events Manager → Pixel ID. You can also find it in your Reddit Pixel Javascript Tracking code in the section above, within the rdt() initialization function.
Reddit Conversions API Access Token - The Conversions API Access Key (token) can be generated in the Reddit Pixel settings. You can follow Reddit's documentation for instructions on how to manually generate a token.
Track Events - Select the events you wish to send to Reddit via the Events API: Purchase / Add to Cart / Add to Wishlist / View Content / Search / Sign Up

Send enabled events via the frontend Reddit Pixel as well - Set this option to Yes if you want to send events via the frontend Reddit Pixel as well. Reddit Ads Manager should have built-in functionality to avoid data duplication, and this may (in some cases) enrich your data.
Enable Test Mode - This functionality can be used to send test events to the Reddit Pixel.
Enable File Log - Enable the creation of a log file that shows the pushed event data. The reddit-api.log file can be found in the var/log directory of Magento 2 root.
Track Only Specific Customer Groups - If set to Yes, only selected customer groups will be tracked by Reddit server-side events.
Send eCommerce Event Data to multiple Reddit Pixel endpoints - Adding a new property here will only send the enabled eCommerce events in the Reddit Pixel Server Side Tracking configuration. If you need to also send Page View events, in order to stitch data and ensure attribution, you'll also need to add additional Reddit Pixel Tracking codes in the Reddit Pixel Tracking Javascript Code section above.
