PayPal provides different types of settlement files like for example DDR, DDL, STL, TRR or ORT, but not all of them will be available daily. The original explanations of these settlement files can be found on the PayPal webpage at https://developer.paypal.com/docs/reports/sftp-reports/.
Basis for the Computop Settlement file CTSF is the PayPal STL Report. The Settlement Report gives merchants and processing partners detailed information about each transaction that affects the settlement of funds to the account. Report details include transaction event code and transaction initiation date.
