AFA.CO — Blockchain Payment Gateway

API keys

Keys work on BNB Smart Chain mainnet: there is no test network. Test your integration with a small real payment (for example 1 USDT). Keep keys on your server, never in a website or app.

Webhooks

Signed POSTs (HMAC-SHA256, AFA-Signature header) to your server. Each endpoint receives only the events it is subscribed to.

invoice.paid— a payment settled (fulfil the order)invoice.underpaid— a wallet payment of at least 1% but less than the invoice amount arrived (smaller ones are ignored; a short QR deposit doesn't send it)invoice.created— a recurring schedule issued a new invoiceinvoice.overdue— a recurring invoice passed its deadline unpaidinvoice.refunded— a refund you sent was confirmed on-chain

Using recurring billing? Subscribe to invoice.created and invoice.overdue too.

Refunding from AFA? Subscribe to invoice.refunded too.
