ModifyInstanceChargeType

Description

Before you call this operation, make sure that you have fully understood the billing methods and pricing schedule of ECS.

When you call this operation, take note of the following items:

• The instance must be in the Running or Stopped state and has no overdue payment.
• After you change the billing method, automatic payment is enabled by default. When your account balance is insufficient, your order will become invalid and you have to cancel this order. If your account balance is insufficient, to prevent your order from becoming invalid, you can set AutoPay to false. This ensures a normal order is generated. Then you can log on to the ECS console to pay for the order.
• Switch of the billing method from subscription to pay-as-you-go:
  • Whether you can convert the billing method depends on your usage amount of ECS instances.
  • After you change the billing method from subscription to pay-as-you-go, the new billing method will take effect for the entire lifecycle of the instance. The price difference is refunded to the payment account you used. Price difference of coupon purchases are not refunded.
  • Refund rule: You can only use a certain amount of refund within a month, and the refund that is not used within the current month will not be accumulated to the next month. After you have used up the refund amount for the current month, you can only change the billing method when the next month arrives. The refund amount incurred when you change billing methods is calculated with the following formula: Number of vCPUs × (Number of remaining days × 24 ± Number of remaining or elapsed hours).
• Switch of the billing method from pay-as-you-go to subscription:
  • You can change all pay-as-you-go data disks attached to an instance to subscription ones.
  • This operation cannot be called if the automatic release time has been set for the pay-as-you-go instance.
