Get purchase 100% detected by FB

  • Hello,

    If soemone know how to write the code in google tag manager to get FB detecting purchases 100%, please help me. It does not need to be the plugin author, whom I dont want to ask for more help from than necessary.

    I use following code in GTM for the FB transaction part:

    <script>
    fbq(‘track’, ‘Purchase’, {
    content_ids: ‘{{ecomm_prodid}}’,
    content_type: ‘product’,
    value: ‘{{transactionTotal}}’,
    currency: ‘SEK’
    });
    </script>

    And the data layer variable I use in GTM is simply ecomm_prodid

    It works for when only one product is purchased but when 2 or more items are purchased FB cant detect or match the products.

    The output from content_ids is: 5601,5610
    I think it should be: 5601, 5610 and then it should work.

    If someone knows how to fix it, please let me know.

    Hi,

    In the Facebook Tag API the content_id is defined as an array when using multiple values:

    https://developers.facebook.com/docs/ads-for-websites/tag-api

    [‘ABC123’, ‘XYZ789’]

    You could use a custom js variable inside GTM that loops through the enhanced ecommerce data and creates that variable for you. To use this, first you need to create another data layer variable that reads the ecommerce key.

    Then you can use this custom js variable:

    function() {
  var prodids = [];

  if ( {{ecommerce}}.purchase ) {
    for(var i=0; i<{{ecommerce}}.purchase.products.length; i++) {
      prodids.push( {{ecommerce]].products[ i ].id );
    }
  }

  return prodids;
}

    Or you can use my script to pass everything to a FB pixel without such coding ??

    Many thanks for your reply. I will look into these instruction even if I can tell you I dont get it completely.

    I did however previously and also again today try your script but can not in my life get my facebook pixel to detect anything at all. The instructions are easy but it did not work for me.

    My page is https://www.batbike.se and your script is activated at the moment.

    What is working at this moment are my own detections. (when I tested I obviously removed those) But your script is installed and the tag is active in gtm if you want to check.

    Hi I checked your site and it seems to me that the FB pixel is working fine.
    Is this issue still present?

    What is working now is my old tags. Your script is active too but does not work. I can turn off my own tags right now temporary if you want to check.

    Now the old tags are turned off.

    //Turned on again//

    I will work on it more another time.
