IP Whitelist & Signature Testing

This is the IP whitelist for callbacks.

If your server requires callbacks, please add these IPs to the whitelist. The IP addresses are subject to rotation, so all IPs in the list need to be whitelisted. The IP addresses may change, and we will do our best to maintain stability. IP address list:

8.212.131.189
8.212.144.5
8.212.147.201
8.212.134.72
8.212.162.123
8.212.132.51
