<div id="body19408657"><p id="cc_01_0013__en-us_topic_0020507759_p1645204610259">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://<em id="cc_01_0013__en-us_topic_0020507759_i137795958918721">Endpoint/uri</em>. In the URL, <em id="cc_01_0013__en-us_topic_0020507759_i842352697154116">uri</em> indicates the resource path, that is, the API access path.</p>
<p id="cc_01_0013__en-us_topic_0020507759_p4816427810259">Public cloud APIs use HTTPS as the transmission protocol. Requests/Responses are transmitted using JSON messages, with the media type represented by <strong id="cc_01_0013__en-us_topic_0020507759_b1025950229154127">Application/json</strong>.</p>
