Azure API Management policies enforce rate limiting and authentication by applying inbound processing rules. You configure validate-jwt and rate-limit-by-key elements within your policy XML to secure APIs before traffic reaches the backend.

Policy-driven routing in Azure API Management directs API traffic to different models using inbound policy snippets. You set backend service URLs dynamically based on context variables to route requests to specific AI integrations.

Azure API Management policies support semantic caching for Azure OpenAI integrations. You implement caching policies within the inbound processing stage to store and retrieve AI responses, reducing backend load and latency.

Transformation in Azure APIM policies modifies request and response payloads using set-body and convert-json policies. Inbound policies transform incoming API traffic, while outbound policies format responses before returning them to the client.

You need basic understanding of API security and XML to apply Azure APIM policy templates effectively. The skill provides reference materials and practical examples mapping to real labs, bridging the gap for teams designing secure APIs.
