Support » Plugin: Facebook for WooCommerce » Facebook EventIDs being duplicated from Swan & Edgar

  • Resolved Brandsoft


    We are using Facebook for Woocommerce on our website and Facebook pixel analytics says that event ids are being duplicated.This is the message we receive from facebook.


    Issue: Same event ID received for many event instances
    You’re sending the same event ID for many instances of your AddToCart events. Event IDs are unique identifiers that are used to deduplicate identical events received from your pixel and the Conversions API so they’re not counted twice. To ensure that Facebook is accurately counting your events, each unique event instance needs its own unique event ID.
    This may cause issues with the measurement of your events and the attribution of your ad campaigns.
    Solution: Check source code
    Update the event_id parameter for your AddToCart events so that each unique event instance is sending a unique event ID from both your pixel and through the Conversions API. For pixel, you can do this on your website’s source code. For Conversions API, you can do this in Graph API Explorer or on your server terminal.

    Hi there,

    troubleshoot Received the same event_id for many events facebook for WooCommerce

    It would be good to enable debug log to see the data being sent by the plugin when it reports those events. Please not that if the site has a lot traffic, logs can grow quickly, so may be a good idea to turn them on for a limited period only.

    The plugin sends events in two ways: using the Server to Server API and using Pixel events on the browser. I’m thinking that is possible that the Pixel snippet got cached and now every person that visits a page that has that snippet is sending the same AddToCart event again and again.

    Please check the website’s source (or using the Facebook Pixel Helper extension) to see if there is a cached event firing all the time.

    We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.

    Hi @zdenys ,

    Having the same issue in my dashboard.
    I am using only the FB for Woocommerce plugin.

    Pixel Helper:

    Showing duplicated Page View, for ex:

    1- PageView – Green Status

    2- PageView – Warning Status

    We detected event code but the pixel has not activated for this event, so no information was sent to Facebook. This could be due to an error in the code, but could also occur if the pixel fires on a dynamic event such as a button click.Learn more
