There is an urgent need for revenue data report from app_fee revenue. The Balance transfer data export on Square merchant dashboard gives the total list of transactions for app free revenue, but it doesn’t map the revenue with merchant_id, location_id and payment_id.
Can these fields be included in the report urgently. There is transaction data available but without correct mapping this data is not effect. Please consider this request a priority.
Currently, There isn’t a revenue data report that’s available if you are collecting app_fee_money. At this time if you want a revenue report for all the fees your app collected you’ll need to ListPayments for every merchant and their locations that your app is collecting a fee from. Parse the results to match the application_id with your apps application_id to get the app fee collected, merchant_id, location_id, and payment_id for all the payments. We’re constantly working to improve our features based on feedback like this, so I’ll be sure to share your request to the API product team. 
Thank you for the update Bryan. I just wanted to clarify further the feature request is for the seller dashboard, where Square already supports data export into csv. It only needs a couple of more fields. I hope the product team is able to update this feature soon.
