Development Scenarios
Huawei Cloud provides open APIs for scenarios, such as product management, transaction management, bill management, enterprise management, and invoice management. Customers can build their own sales platforms based on the operation capabilities.
The following figure illustrates the specific scenarios.

The preceding figure does not show the independent scenario. You can invoke this interface based on the site requirements.
Product Management
Customers can query the cloud service or resource types, query resources by cloud service type, or query usage types, measurement units, and measurement unit number system on the self-built platform.
Account Management
Customers can query their account balance at any time. If the balance is insufficient, they need to top up the account as soon as possible. In addition, they can check their expenditure quota. An expenditure quota is the maximum expenditure amount that a customer can spend each month on Huawei Cloud. It is not a payment method. Customers cannot use the quota for payment or as a basis for reconciliation or payment.
Transaction Management
Customers are allowed to query coupons issued by their partners, product price, package usage, resource packages, and resource package usage; purchase yearly/monthly resources; and manage orders.
Bill Management
- A customer can query its expenditure summary bills, which contain detailed expenditure records and can be used for reconciliation.
- A customer can query its resource details. The resource details have a latency (a maximum of 24 hours).
- A customer can query its usage details of each resource.
Enterprise Management
- Enterprise Project Management Service (EPS) provides a unified method to manage cloud resources and personnel by enterprise project.
Invoice Management
Customers can view the invoice list on the self-built platform.
