Hi Gabriel, It looks like you are setting the attributionModelType to DATA_DRIVEN. Please note that this attribution model is only available to accounts with enough data. The requirements for this attribution model are provided here <https://support.google.com/adwords/answer/6394265>. This could be the reason these requests are failing. Could you check if this account has the " *Data-driven*" option for the “*Attribution model*” setting in the UI?
