Hi @nilewm
Thanks for your question!
`I also reimplemented the Facebook API integration and confirmed with my Facebook ads manager that the API is firing correctly. However, I’m still getting deduplication errors.
I’m thinking this is a plugin issue because I am receiving multiple “browser” events from the ‘partner integration’ being the facebook for woocommerce plugin.
The facebook pixel code is only on my website via the plugin as I’ve verified by turning the plugin off and checking the pixel helper as mentioned previously.`
We can confirm that by default, the plugin, intelligently deduplicates events that are sent both from the browser pixel events and server-to-server events (Conversions API) to ensure no double-counted events.
Excerpt from our blog:
With the Facebook for WooCommerce plugin, the same data that flows through Conversions API and the Facebook Pixel is deduplicated based on a unique event ID, so there’s no concern about the same events being double-counted.
This could be an intermittent issue affecting some users as I don’t have a similar issue and it’s not widespread.
However, we have an open bug report regarding this Missing Some Deduplication Parameters and our devs are working to ensure this resolved.
If you have made sure no other plugin that does FB pixel and also no caching plugins that could affect it, for now, I’d suggest manually click “Resolve” or “Ignore” on the Facebook site as we keep monitoring this and working on the above mentioned open issue, and also working with Facebook to ensure the accuracy of the report.
Or as a work around you can temporarily disable the auto pixel injection using the following code snippet:
add_filter( 'facebook_for_woocommerce_integration_pixel_enabled', '__return_false' );
You can use Code Snippet plugin to insert this code.
And then, you can keep Facebook for WooCommerce for the products syncing, while for Facebook pixel, you can use another plugin that does Facebook pixel for example, Facebook for WordPress by Facebook.
I hope that helps!
