You work for an ecommerce company and are designing a new Orders API to be exposed through Apigee. You created two environments in your Apigee organization: orders-test and orders-prod. You intend to use distinct URLs—test.lnk-42.com/api/v1/orders for the test environment and lnk-42.com/api/v1/orders for production. How can you ensure each environment exclusively uses its assigned URL?
