SFTP Access Setup for Merchant
Purpose
This document outlines the prerequisites and setup process for enabling SFTP access for the merchant to securely exchange files with Juspay.
1. Prerequisites from Merchant
The merchant must share the following details for SFTP access configuration:
1. Merchant's NAT IPs
The list of NAT IP addresses from which the merchant will connect to the SFTP server.
These IPs will be whitelisted at Juspay's end.
Connections will be restricted only to the provided NAT IPs — access from any other IPs will not be allowed.
2. Public Key for Authentication
RSA 2048-bit public key to be used for key-based authentication.
The corresponding private key must be securely maintained by the merchant.
2. Access Configuration by Juspay
Once the above details are received, Juspay will:
Configure SFTP access and whitelist the provided NAT IPs.
Create a dedicated SFTP user for the merchant.
Share the credentials securely over email.

5. Additional Notes
Only the whitelisted NAT IPs will have access to the SFTP server.
The merchant will not be able to access the SFTP from any other location or network.
Authentication will be strictly through the RSA 2048 public/private key pair.
