  29. What are main differences between API and Web Service?

    - All Web services are APIs but not all APIs are Web services.

    - Web service uses three styles of use: SOAP, REST and XML-RPC for communication whereas   API  may be exposed in multiple ways.

   -  Web service needs a network to operate but APIs don’t need a network to operate.

 30. What is REST?

- REST (Representational State Transfer) is an architectural style for developing web services which exploit the ubiquity of HTTP protocol and uses HTTP method to define actions. It revolves around resource where every component being a resource that can be accessed through a shared interface using standard HTTP methods.

- In REST architecture, REST Server provides access to resources and client accesses and makes these resources available.

 
- Each resource is identified by URIs or global IDs, and REST uses multiple ways to represent a resource, such as text, JSON, and XML.

Difference between API status code 401 and 403?

 

Check below link for question SET-01:
Top API Interview Question 1-10

The 401 (Unauthorized) status code indicates that the request not applied because it lacks valid authentication credentials for the target resource.
The 403 (Forbidden) status code indicates that the server understood the request but refuses to authorize it.

Frequent Cause
The 403 error can occur when a user able to login but don't have sufficient privileges to access the requested resource. For example, a normal user attempting to load an 'admin' route.
The most obvious time for 401 error, is when you have not logged in at all, or provided the incorrect password. If authentication credentials were provided in the request, the server considers them insufficient to  grant access.

Rare cause
403 errors can occur because of restrictions not entirely dependent on the logged in user's credentials.
401 errors can occur even if the user enters the correct credentials. This is rare, and might be something you only really encounter while developing your own authenticated back ends.
But if the authorization header is malformed it will return a 401. 

API Testing Interview Questions

Conclusion:
401 Unauthorized response should be utilized for missing or bad authentication, and  403 Forbidden response should be used afterwards, when the user is authenticated but isn’t authorized to perform the requested operation on the given resource.
