# Connect to Fiserv, FirstData, and BAMS

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](/importing-data/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.

## 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

<Tip>
  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.
