After creating an API, you can publish it for testing. Create an app and access a second-level domain name to call the API to be tested. For how to call an API, see User Manual (Call an API).
You can publish an API to production after it is bound to an independent domain name. After you authorize your customer’s app to access the API, your customer can access the independent domain name to call your API in the production environment.
You can use the API Gateway to manage the API version in the test or production environment. You can publish the app, remove the app, or switch the API version. Version switching takes effect in real time.
