At this level, individuals are expected to have a basic understanding of what API Management is and how it works. They should be familiar with the Azure portal and have a basic knowledge of RESTful APIs. This level is about gaining an initial exposure to the concept of API Management.

Novices can create an API Management instance in the Azure portal, import and publish an API, and set up a developer portal. They understand API policies but may not yet be comfortable configuring them. This level involves learning the basics and starting to apply them.

Intermediate users can confidently configure API policies, manage users, groups, and subscriptions, secure APIs with OAuth 2.0, monitor APIs with Azure Monitor, and transform APIs using inbound policies. At this level, individuals are able to handle common tasks independently.

Advanced users can scale an API Management instance, automate API Management with Azure Resource Manager templates, integrate API Management with Azure Functions, implement rate limiting and quota policies, and troubleshoot common API Management issues. This level involves deeper understanding and ability to handle complex tasks.

Experts can design and implement a custom developer portal, optimize API Management performance, implement advanced security features, migrate APIs between environments, and customize API responses using outbound policies. At this level, individuals are able to handle highly complex tasks and provide solutions for unique scenarios.
