The AR Posting Service provides a query for the AR Posting data for a given merchant and time range. The AR Posting data represents the information used to post payments to the merchant's ERP or accounting system, generally including the date the payment was processed, the customer's account number and applied payment amount. The information included in a given date range is the AR Posting data that was marked for inclusion in the AR Model for that date range and matches to the information included in reports and extracts for that same date range.
