This guide outlines the necessary steps to connect your Pagos account to a Fiserv, FirstData, or Bank of America Merchant Services (BAMS) account. For more information on connecting Pagos to other payment processors, see our Connecting Your Payment Processors to Pagos guide. After you successfully connect your accounts, we’ll import your payments data into Pagos once a day via a secure file transfer protocol (SFTP), starting with the first day of the successful connection. We can also import historical payments data upon request; reach out to your Pagos account team and processor relationship manager for more information.
After connecting and importing your data into Pagos, you may notice slight differences between Pagos and your processor’s reports. If reconciliation reveals discrepancies you can’t account for, submit a Data Audit Request.

Connecting to Pagos

To send payments data from your Fiserv, FirstData, or BAMS account to Pagos, you must first set up a new designated CLX SFTP mailbox. Even if you already have a CLX mailbox, we recommend setting up a new one specifically for connecting to Pagos. Once you establish the mailbox, schedule all fields to be automatically generated on a daily basis for the following data types and with these recommended file names:
  • Authorizations (CSV format) - *Pagos_Auth_Daily
  • Chargebacks (XLS format) - *Pagos_Disputes_CB_Daily
  • Inquiries (CSV format) - *Pagos_Inquiries_Claims
  • Settlement (CSV format) - *Pagos_Settlement_Daily
  • Settlement Fee (CSV format) - *Pagos_Settlement_Fee
  • Funding (CSV format) - *Pagos_Funding_Daily
You’ll need to name both your schedules and the files themselves within your Fiserv, FirstData, or BAMS account; we recommend naming them something related to Pagos for easy identification in the future.
