Top Api Developer Interview Questions
Essential questions for evaluating API Developers
Can you explain the difference between REST and SOAP APIs?
Look for an understanding of how REST is typically stateless, uses standard HTTP, and is generally easier to integrate and scale, whereas SOAP is protocol-based, more rigid, has built-in error handling, and is often used in enterprise environments requiring ACID compliance.
What methods are typically used in RESTful services, and when would you use each?
Expect the candidate to mention HTTP methods like GET (retrieve), POST (create), PUT (update), DELETE (remove) and PATCH (partial update), explaining scenarios in which each would be used, showcasing their practical understanding.
How do you ensure the security of an API?
Listen for knowledge of authentication protocols like OAuth, JWT, API keys, encryption, rate limiting, and secure data transmission practices to gauge their ability to build secure APIs.
What tools do you use for API testing and why?
They should mention tools like Postman, Swagger, or Insomnia and emphasize automated testing for reliability, regression testing, and their approach to creating comprehensive test cases.

Check for their resourcefulness and continuous learning mindset. Effective candidates will discuss utilizing documentation, online resources, and hands-on practice.
