Application Programming Interface

API - Application programming interface, IPN - Instant Payment Notification.
If you don't accept the variant with fixed amount payment button, then API+IPN will be glad to help any programmer. Payment, that valid for payment only 15 minutes, can be created by REST/JSON-RPC call. ALFAcoins send notification to merchant on status change for payment. Status definition can be location on statuses page.
All requests are only available via HTTPS, in the interest of security best practices we do not support API calls over HTTP.
We support both REST and JSON-RPC calls. To use JSON-RPC calls please add .json at the end of request.
Add our IP 138.201.230.93 to whitelist.

POST Requests

We support both REST and JSON-RPC calls. JSON-RPC is recommended as we will deprecate REST over time.
