Creating an Environment Variable

You can define environment variables to allow an API to be called in different environments.

Environment variables are manageable and specific to environments. You can add variables in different environments to call different backend services using the same API.

For variables you define during API creation, you must create corresponding variables and values. For example, variable Path is defined for an API, and two variables with the same name are created and assigned values /Stage/test and /Stage/AA in environments 1 and 2, respectively. If the API is published and called in environment 1, the path /Stage/test is used. If the API is published and called in environment 2, the path /Stage/AA is used.
