Dear User,
To further enhance system security and stability, TTPay has completed a system upgrade. Effective immediately, all API calls require adding IP addresses to the whitelist in the backend to function properly.
Please promptly log in to your merchant backend, navigate to [Application List] > [Edit IP Whitelist], and enter your server IP address before saving. Requests without configured IP whitelist entries will be rejected by the system.
We appreciate your understanding and support. We remain committed to delivering a more secure, stable, and efficient service experience.
TTPay
