Web API Development with Flask (Video 16)

This video tutorial covers error handling in RESTful APIs, focusing on HTTP response and error codes. It discusses when to use standard codes and when to implement custom ones, emphasizing the importance of consistency and predictability. The tutorial also explores error handling in middleware, using try-except blocks and custom headers. It concludes with testing and validating API responses using Postman, highlighting best practices for creating developer-friendly APIs.

Why is it important to use the correct HTTP response codes in a RESTful API?

• To ensure all responses are HTTP 200 success codes

• To increase the number of custom solutions required

• To ensure the API is more developer-friendly and predictable

• To make the API more complex and challenging to use

What should be considered before adding custom error codes to an API?

• The length of the API documentation

• The color scheme of the API interface

• The number of developers using the API

• Whether the standard HTTP error codes can resolve the issue

What is the purpose of the X app error code in the HTTP header?

• To indicate the success of the API request

• To provide a custom error code specific to the application

• To show the time taken for the API response

• To display the server's IP address

What happens when a negative ID is passed to the delete method in the API?

• The API crashes and stops responding

• An HTTP 200 success code is returned

• The candidate is deleted successfully

• An HTTP 500 internal server error is returned

What is the significance of having an empty body in the HTTP response?

• It shows that the server is down

• It suggests that the API is not functioning

• It means the request was successful

• It indicates that the error information is only in the headers
