Remittance Files

Regardless of whether you are using our File Transfer system through a SFTP connection or by uploading files through the Dashboard, SlimPay supports a range of remittance file formats that allow merchants to deposit batch orders on our server.

This means you can process multiple payment orders (direct debits, credit transfers), update customer bank details, create, modify or cancel payment schedules, create Back Office user accounts or import existing mandates. . . using a single CSV file for each type of order.

Please note: The documentation below is for injecting remittance orders using our v1 format. To inject batch SEPA direct debit payments using the v2 format, please refer to our payments documentation for the appropriate file structure.

There are three types of lines contained in the remittance file: Header, Operation order and Footer. A remittance file requires one header and one footer, but there is no limit on the number of operation order lines. This means you can process dozens, hundreds or even thousands of orders in a single transaction!

Each file can only contain one type of order, meaning that direct debits, credit transfers or any other type of order must be sent in separate files. The merchant must ensure the remittance files provided comply with the different formats described on this page.

Header line

The first line of the remittance file is the header line. It mostly contains the merchant's information, allowing SlimPay to find the corresponding details stored on the server. The line consists of 14 fields, each separated by a semi-colon ;.

o = optional)		Max number

1 Type of line 0 (zero) for the first line of the file M 1
2 Merchant reference Unique value provided by SlimPay for each merchant. If the Merchant has divided their activity into several entities this field must contain the value: Merchant reference-Merchant entity (dash separated) M for mandate migration and bank account updates (file types 4 and 14) 35

Operation order line

Each operation order is represented by its own line in the remittance file. Made up of 33 fields (each separated by a semi-colon ;), each line consists of information about the user and the specific order/payment details.

You can find the structure of the various remittance file formats by clicking on the tabs below:
