5.1Exposing APIs with API Management

Key points

Understand exposing backend APIs with Azure API Management (APIM): authentication, throttling, policies (transform/cache), and products/subscriptions. The starting point for "Connect to and consume services" in AZ-204.

Azure API Management (APIM) exposes multiple backend APIs through one secure front door, centrally managing auth, throttling, and transformation via policies.

5.1.1What APIM does

Diagram showing clients (apps/partners) → API Management (gateway: auth, rate limiting, policies for transform/cache, products/subscriptions) → backend APIs (Functions/App Service), depicting APIM fronting backends for auth/throttling/transform/product packaging.
API Management topology
  • Gateway: protect backends with auth (subscription key/JWT validation) and throttling (rate limits).
  • Policies: declaratively apply transformation, caching, header manipulation, CORS to requests/responses.
  • Products & subscriptions: bundle APIs into products and offer/limit them to consumers via subscription keys.
Exam point

Common on AZ-204: expose/auth/throttle multiple APIs = APIM, transform/cache/CORS = policies, per-consumer offering = products + subscriptions. Rate-limit policies prevent overuse.
