How do you transform requests and responses in APIM?

Short answer: Use policies like <set-body>, <set-header>, <rewrite-uri>

Example code

Add a custom response header: <set-header name="X-Custom-Header" exists-action="override"> <value>API Managed</value> </set-header>

Real-world example (ShopNest)

ShopNest on Azure typically uses App Service + SQL Database + Blob Storage + Application Insights for monitoring.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
