If you're integrating the API and something isn't behaving as documented, include your payment ID or request ID when you write in — it lets us find the exact transaction right away. The full API reference is available at https://biswasto.com/docs.

Security issues

If you believe you've found a security vulnerability, please report it privately rather than opening a public issue, so it can be fixed before details are shared publicly.
