10. Error Handling

In this chapter, we'll introduce the concept of RESTful APIs, discussing their benefits and principles. We'll also highlight the importance of adhering to the principles for building scalable and maintainable APIs.

Effective error handling provides meaningful feedback to clients. A well-designed error response includes:

  • Status Code: Indicates the type of error (e.g., 404).
  • Message: Describes the error in a human-readable format.
  • Error Code: Optional code for programmatic error handling.
