USDT BEP20 Payment Gateway API
Accept USDT on BNB Smart Chain (BEP20) in your store or app. Payments go straight to your own wallet address — ALU API creates the payment request, verifies the transaction on-chain and notifies your server when it is confirmed.
You design the payment screen; the API gives you the exact amount, address and expiry to show your customer.
How it works
- Save your USDT (BEP20) receiving address in your profile.
- Create a payment for the amount you want to receive.
- Your customer sends exactly that amount before it expires.
- Submit the transaction hash — your webhook fires once it is confirmed.
