What is the difference between Web Apps and API Apps in Azure?

Short answer: Web Apps: Designed for websites, support Razor Pages, MVC, and Blazor. API Apps: Optimized for RESTful APIs, includes built-in Swagger support and API authentication features.

Real-world example (ShopNest)

ShopNest’s API runs on Azure App Service with staging slots—swap staging to production after smoke tests.

Say this in the interview

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
