An app is your identity to call an API. The identity and permission verification during API calling is specific to apps. In the API Gateway, calling an API requires authorization, which is also granted to the corresponding app.
When creating an app, you must specify a unique name for the app under your account.
After an app is created, the system assigns the app an AppKey and AppSecret which are encrypted as the signature information. Your request must include the signature information. Based on this, the gateway verifies your identity. For more information of apps, see App.
