Enabling Auto Payment

Application Scenarios

• You can enable auto payment to perform transactions using APIs. Transactions include new purchase, manual renewal, specification upgrade, renewal with specification changes, and change from pay-per-use to yearly/monthly.
• You can enable auto payment for your member accounts associated in unified accounting management mode. The orders of these member accounts will then be automatically paid by your master account by default.
• When you purchase a Huawei Cloud solution, the system automatically deducts the fee by default and then deploys the solution.
• You can also enable auto payment for auto scale-out or auto scaling of cloud services. For example, payment is automatically made to create a cloud container node pool.

Auto Payment Rules

1. Payment Sequence

   The system automatically pays bills from your account balance (available credit) or by using monthly settlement (preferred). Discounts and cash coupons can also be used in the following sequence:

   Discount (only one at a time) → Cash coupon (only one at a time) → Account balance ( available credit) or monthly settlement

   If both discounts and cash coupons are applicable, the system uses them in sequence.

2. Discounts Usage
   The following rules apply only to valid discounts:

   1. The system selects the best discount from applicable discounts (commercial discounts, discounts set by partner, and promotional discounts). Promotional discounts are used only in certain scenarios.
      

      Constraints on using promotional discounts:

      • In manual renewals, specification upgrades, and renewals with specification changed scenarios, if a resource has a historical order (for example, a new purchase order) with a promotional discount applied, the system compares the promotional discount with the commercial discount and the discount set by partner. The system then selects the promotional discount if it is the best one.
      • In some scenarios, such as new purchase or change from pay-per-use to yearly/monthly, promotional discounts cannot be used because there are no historical orders. You can only use the promotional discounts on the promotion page. For details, see the specific rules there.
      • Historical orders refer to the orders that exist before the current order is created. For example, if you place a new purchase order and then initiate specification changes, resulting in a second order. In this case, the first order is considered as a historical order relative to the second one. If a promotional discount was applied in the first order, the system can apply this discount when the second order is automatically paid.

      Example: Suppose you placed an order for a cloud service on November 20, 2024, with a promotional discount of 25% off applied. On December 20, 2024, you wanted to modify the cloud service, and you had the following applicable discounts: commercial discount (20% off), discount set by partner (10% off), promotional discount (25% off), and promotional discount (30% off). In this case, the system compares the promotional discount (25% off) that had been applied in the historical order with the commercial discount (20% off) and the discount set by partner (10% off). As the promotional discount (25% off) is the best one, the system selects it when calculating the price of the order.

   2. If the commercial discount, discount set by partner, and promotional discount offer equivalent benefits, the discounts will be applied in the following priority: commercial discount, followed by discount set by partner, and then promotional discount.
3. Coupon Usage

   The following rules apply only to valid cash coupons:

   1. The system searches all valid cash coupons in your account and compares the balance of each cash coupon with the amount to be automatically paid.
      • Cash coupon balance ≥ Amount to be automatically paid

        Rule: The cash coupon expiring first will be used first. If multiple cash coupons expire at the same time, the coupon with the largest balance will be used first.

      • Cash coupon balance < Amount to be automatically paid

        Rule: The cash coupon with the largest balance will be used first, and then the account balance (available credit) or monthly settlement will be used for payment. If multiple cash coupons have the same balance, the one expiring first will be used first.

   2. When auto payment is enabled, the system locks the amount to be deducted from the selected cash coupon, and automatically deducts the amount during the payment. If the payment fails or times out, the amount will be unlocked.
