Do we have to be a programmer to build an API? How to build an API in less time? Could a Data/Infrastucture engineer build an API?

Yes, it's possible

Azure provides lots of services to build serverless solutions. In this session I would like to take an enterprise requirement for designing an API without writing code using Azure services in a managed way, allowing to take control through policies, add security, insights, provide decoupling between frontend and backend. We can enrich our services with capabilities like caching, throttling, advanced security, and even protocol and data translations.
