Whitelisting your IP address provides a layer of authentication. This prevents unauthorised API requests and ensures only verified requests are processed.
IP whitelisting is required only for the production environment. The test environment does not require whitelisting.
To whitelist your IP address, follow these steps:
  1. Log in to the Merchant Dashboard. Go to Developers > Two-Factor Authentication under the Secure ID card.
  2. Select IP Whitelist from the Select 2FA Method drop-down.
  3. Select Add IP Address.
  4. Enter the IP address you want to whitelist and select Add IP Address to save.
The whitelisted IP addresses are displayed in the grid. Grid showing whitelisted IP addresses in the Cashfree Secure ID dashboard
  • Whitelist your IPv4 address only. IPv6 addresses are not supported.
  • You can whitelist a maximum of 10 IP addresses.
  • Generate your API credentials before you set up two-factor authentication (2FA).
  • Ensure that you whitelist a public IP address. Cashfree does not support private IP addresses, including the 10.x.x.x, 172.16.x.x–172.31.x.x, and 192.168.x.x ranges, as these are not accessible over the public internet.
