We recommend you switch off any duplicate Facebook Pixel tracking as part of installing Littledata's Facebook Conversions API connection
Using Shopify's Pixel (or any other Pixel app) alongside Littledata's connector leads to double tracking of events and purchases. You need to disable the built-in Pixel when you install.
You may also need to unlink the Ad Account used in the Facebook Channel. WARNING: this may stop ads running.
Finally, check the page views and View Content events are only triggered once from your pages, by using the Facebook Pixel Helper plugin for Chrome.
