C Payment lets merchants generate a QR code for USDT, USDC, BTC or BNB and receive webhook callbacks the moment funds arrive. Integrate in minutes with HMAC-signed REST APIs.
Merchant sends amount + currency; we return a one-time deposit address and QR code. Payment closes the order automatically.
Assign a persistent address to a customer. Any incoming deposit fires a signed webhook keyed by the customer ref.
Every request signed with SHA256. Timestamp + nonce protect against replay.
Manage API keys, callback URLs, and drill into every transaction with webhook delivery history.
Signed webhooks on payment received. Retry with one click from the portal.
