This manual explains how to call APIs through Alibaba Cloud API Gateway, covering request structure, signing, and app management.
The document provides step‑by‑step instructions for using the API Gateway to invoke APIs offered by other Alibaba Cloud users or third‑party providers. It describes how to construct HTTP requests, include required headers, and compute the cryptographic signature.
It also details the creation and management of APPs, including the automatic generation of AppKey and AppSecret, usage limits, and the process for obtaining API authorization from service providers. This manual is written in Chinese.

When you create an APP in the API Gateway console, the system automatically assigns a pair of AppKey and AppSecret.
The mandatory headers are X‑Ca‑Key (AppKey) and X‑Ca‑Signature (signature string). Other headers such as X‑Ca‑Timestamp are optional.
An account can create up to 10 APPs.
