IP Whitelisting

If you are whitelisting inbound connections from PlugnPay to your systems you will need to whitelist the following IP addresses:

18.214.78.64
52.3.174.161
54.91.210.62
69.18.198.4
107.22.32.178

Callback Timeout

The connection will timeout after 20 seconds.

Ensure that the method you are using to handle the callback will respond in a timely manner.

Domain names vs. IPs in callback URLs

When using a domain name as your callback URL the domain name must be fully qualified.

Example:
https://www.mydomain.com/mycallbackurl.html

If using an IP address within a callback URL there are a few requirements to note:

  1. Using an IP in a callback URL will only work when using HTTP
  2. Only public IPs are allowed in callback URLs.

Using ’localhost’ as part of your callback URL is not supported.

SSL Specifications

Self signed certificates are not supported.
