Overview

Clink delivers a daily settlement file to a secure SFTP directory. You can connect an SFTP client (or your own automated job) to pull these files for bookkeeping and internal reconciliation.
Files are read-only. The SFTP account is provisioned per merchant and only grants access to your own files.

​
Get Your SFTP Credentials

Connection only supports SSH key authentication.
  1. Generate an SSH key pair on your side and keep the private key secure:
  2. Go to your merchant dashboard and open the Developer menu
  3. Click Request SFTP and:
    • Paste the contents of your public key (clink_sftp.pub). It must be a single line. Use tr -d '\r\n' < clink_sftp.pub to remove line breaks before copying
    • Supported key algorithms are Ed25519, ECDSA, and RSA (at least 2048 bits). DSA is not supported
    • Add 1 to 5 IP allowlist entries. Each entry must use a CIDR prefix from /24 to /32 (e.g. 203.0.113.7/32, 203.0.113.0/24)
Connection details:
  • Host: sftp.clinkbill.com
  • Port: 2022
  • Username: your merchant ID
  • Authentication: SSH key only

​
Manage Your SFTP Configuration

​
Rotate Your Public Key

To rotate a key or replace a compromised key, open the SFTP configuration from the Developer menu, click Edit, and replace the public key.
Replacing the public key immediately disconnects active SFTP sessions and interrupts downloads in progress. Make this change outside your scheduled download window, then reconnect using the matching private key.

​
Request Historical Files

The scheduled job generates only the previous day’s file. Settlement files from before your first SFTP request are not added to /statements automatically. Contact Clink support to request historical files.

​
Connect

Using the OpenSSH client:
You can also connect with an SFTP client application (FileZilla, WinSCP, or Cyberduck) using the host, port, merchant ID, and private key above.

​
Settlement Files

Settlement files are placed in the /statements directory at the root:
A new file for the previous day is generated daily at 02:00 UTC, named settlement_report_YYYYMMDD.csv.
