The Correct Way to Return Error Responses from Your Backend Application or API

⚡️Returning the correct HTTP status code alone is not enough; the client may need more information to handle the error properly.

🌐The Problem Details specification (RFC 7807) provides a standard way to convey detailed error information in API responses.

🛠️.NET provides built-in support for handling and constructing Problem Details responses, making it easy to follow the specification.

🔎Problem Details responses include properties like 'type', 'title', 'detail', and 'extension' to provide comprehensive error information.

⬆️Using the Problem Details specification improves the scalability and consistency of error responses in your API.

Why is returning the correct HTTP status code not enough?

—While the status code indicates the general nature of the error, clients often need more details to handle the error properly. The Problem Details specification provides a standardized way to convey additional error information.

What is the Problem Details specification?

—The Problem Details specification (RFC 7807) defines a format for returning detailed error information in API responses. It includes properties like 'type', 'title', 'detail', and 'extension' to provide comprehensive error descriptions.

Does .NET support the Problem Details specification?

—Yes, .NET provides built-in support for constructing and handling Problem Details responses. This makes it easy to follow the specification and provide consistent error responses in your backend applications or APIs.

What information does a Problem Details response contain?

—A Problem Details response includes properties like 'type', 'title', 'detail', and 'extension'. These properties allow you to provide specific error information, such as the type of error, a short title, additional details, and custom extensions.

How does using the Problem Details specification improve API error handling?

—By adopting the Problem Details specification, you ensure consistency in error responses across your API. Clients can rely on a standardized format and easily extract relevant error information, improving error handling and troubleshooting.
