API Usage Guidelines¶
Public cloud APIs comply with the RESTful API design principles. REST-based Web services are organized into resources. Each resource is identified by one or more Uniform Resource Identifiers (URIs). An application accesses a resource based on the resource's Unified Resource Locator (URL). A URL is usually in the following format: https://Endpoint/uri. In the URL, uri indicates the resource path, that is, the API access path.
Public cloud APIs use HTTPS as the transmission protocol. Requests/Responses are transmitted by using JSON messages, with media type represented by Application/json.
For details about how to use APIs, see API Usage Guidelines.
An endpoint is the request address for calling an API. Endpoints vary depending on services and regions. For example, the endpoint of the eu-de region is ces.eu-de.otc.t-systems.com. For the endpoints of all services, see Regions and Endpoints.
