Notes

  1. The address after placing the order is permanent. After each payment, a callback will be triggered, and the platform order number (orderNo) and merchant order number (orderId) will be different each time. However, the same order will trigger repeated callbacks (up to 5 retries) with the same values.
  2. If a collection address already exists for a particular network protocol, the requested currencies will be updated to the already bound address. The update method is overwrite, and the original currency will no longer be supported. Please proceed with caution.
  3. Only the selected Payment Methods can be used for the order. Unselected currencies are not supported for payment. If funds are forcefully transferred, they will not be credited and no callback notification will occur. To avoid financial loss, please confirm before making the payment.
