How do I allowlist my server’s IP address so it can access PayPal APIs?

Here's how: 

1. Log in to your PayPal Manager account. 
2. Select Account Administration > Allowed IP Addresses (For API Transaction Processing). 
3. Enter up to 16 server IP addresses to allowlist, then click Update.

• To represent a range of IP addresses, use the asterisk (*) character.
• Each IP address must be Internet-facing.

• Only admin users can modify this information. If you don't have admin privileges, you can view only the allowed IP addresses.
• Access from all IP addresses outside your specified list is blocked.

We don’t require merchants to allowlist specific IP addresses to access Classic or REST APIs. However, we do offer optional IP address allowlisting features for Payflow Pro via PayPal Manager.
