Hi, Thank you for reaching out to the Google Ads API support team.
By reviewing your query, I understand that you want to upload conversion adjustments using an MCC account through the Google Ads API. Kindly note that the account that manages the conversion actions is able to import adjustments. If the MCC account manages the conversion actions, then you can upload the conversion adjustments using an MCC account. Kindly note that If you are attempting to import an adjustment using a different account, or if the conversion action of the adjustment is not enabled, then you will encounter NO_CONVERSION_ACTION_FOUND error. To determine the owner of the conversion actions, please find the below GAQL query: SELECT conversion_action.id, conversion_action.name, conversion_action.type, conversion_action.status, conversion_action.owner_customer FROM conversion_action WHERE conversion_action.id = {conversion_action ID} In order to adjust a conversion, you must first have a conversion action set up, and you must also have recorded the conversions that you are about to adjust. Kindly note that you should follow all the requirements while adjusting conversions using the ConversionAdjustmentUploadService in the Google Ads API. I would recommend you to refer to Import Conversion Adjustments documentation for more detailed information. I hope this helps! If you are still facing any issues, kindly get back to us with more details. Thanks, Google Ads API Team Feedback How was our support today?
