Connection issue between Facebook ads and Data Studio


I'm new on google data studio and I'm trying to do a basic table with my campaign names, Leads and costs. The problem is that I can't get the right number of conversions in google data studio. I have a custom conversion on Facebook ads that gives me the right number of leads I get. But on Google data Studio, when I pick this custom conversion as a metric, I don't get the right figures. 

Thank you in advance for your responses. 

  • Hi Mathieu,

    Thank you for contacting us! We are sorry to hear about this issue.

    The most common reason for seeing a discrepancy is mismatching with the time zone or conversion window between your Supermetrics report and the original data source interface. 

    You can find more information here:

    The above issue could be related to the recent iOS 14 changes by Facebook. Hence, I also link our supporting articles which describe the detailed information about the changes:

    If the discrepancy still appears and you have checked that all conditions match, could you please send us a new ticket with screenshots of the results you see in the original data source interface and the results in the Supermetrics tool.

    Very best
    Meri / Supermetrics Support
