Error Handling in APIs

Proper error handling is crucial for a good user experience. It allows developers to understand what went wrong and how to fix it.

Common Error Codes

APIs typically return standard HTTP status codes to indicate the result of a request:

• 200: OK - The request was successful.
• 400: Bad Request - The request was invalid.
• 401: Unauthorized - Authentication failed.
• 404: Not Found - The requested resource does not exist.

Providing clear error messages along with these codes can greatly assist developers in troubleshooting.
