In a hypothetical scenario at the Paris, Texas Regional Airport, an API product owner manages two main APIs, Flights API and Scheduling API, each requiring distinct authentication strategies tailored to different user groups. Research institutions need read-only access to flight and gate information, whereas airline partners require both read and write access. By utilizing a single Auth0 DCR provider, the owner creates two authentication strategies: one with read-only scopes for Flights API v2 and another with read-and-write scopes for Scheduling API v2. These strategies are applied to their respective API Product versions through the POST v2/portals/{portalId}/product-versions endpoint, allowing for flexible authentication configurations across different portals. This approach, leveraging the concept of Portal Product Versions, enables the publication of API Product versions with suitable auth strategies, ensuring that research groups and airline partners receive appropriate access based on their needs. The initiative demonstrates how to maintain robust security while catering to diverse user requirements within the same platform.
