Which programming language is used in this course?

We use Node.js/TypeScript for examples, but the principles apply to any language. The focus is on API design patterns and best practices.

Will I learn both REST and GraphQL?

Yes, we cover both REST and GraphQL, helping you understand when to use each approach.

Do you cover API security?

Absolutely! Security is a major focus, including authentication, authorization, rate limiting, and protection against common vulnerabilities.

Will I learn to write API documentation?

Yes, we teach you how to create comprehensive API documentation using OpenAPI/Swagger and other industry-standard tools.

What are the prerequisites for the Web API course?

Programming experience in any language, a basic understanding of HTTP and some database knowledge. Code examples use Node.js and TypeScript, so basic JavaScript helps.

Is the Web API course online or in Anand?

Both. Batches run live online for learners anywhere in India and as classroom training at TechNet, F-6, 1st Floor, Vihang Trade Center, Mota Bazaar, Vallabh Vidyanagar, Anand, Gujarat 388120. Learners from Nadiad can join online or attend in Anand; TechNet has no physical training centre in Nadiad. Contact us to confirm the current batch format and timetable.

What projects will I build, and is this useful for ASP.NET Core developers?

You build a secure REST API for a product catalogue, a GraphQL API with advanced queries and an API gateway with rate limiting. The design, security and documentation skills apply directly to ASP.NET Core, and our blog has a step-by-step ASP.NET Core Web API tutorial with JWT authentication for C# developers.
