# Best Practices for API Error Handling  ## Metadata - Author: [[TECHCOMMUNITY.MICROSOFT.COM]] - Full Title: Best Practices for API Error Handling - Category: #articles - Summary: APIs are important for software development, but they can encounter errors that need careful handling. Effective error handling improves system reliability and user experience by providing clear messages and preventing sensitive information exposure. Following best practices, like using standard HTTP status codes and consistent error formats, helps developers manage API errors better. - URL: https://techcommunity.microsoft.com/discussions/appsonazure/best-practices-for-api-error-handling-a-comprehensive-guide/4088121 ## Highlights - API error handling is crucial for several reasons: 1. Maintaining System Reliability: Errors are inevitable in any system. Proper error handling ensures that when errors occur, they are handled in a way that prevents them from cascading and causing further issues. 2. Enhancing User Experience: Clear, informative error messages can help users understand what went wrong and how to resolve the issue, improving overall user satisfaction. 3. Security: Proper error handling helps prevent sensitive information from being exposed in error messages, reducing the risk of security breaches. 4. Debugging and Monitoring: Effective error handling makes it easier to identify and debug issues, leading to quicker resolutions and improved system performance.

Implement Retry Logic for Transient Errors For errors that are likely to be transient, such as network timeouts or service disruptions, consider implementing retry logic on the client side. However, retries should be implemented judiciously to avoid overwhelming the server with repeated requests. ([View Highlight](https://read.readwise.io/read/01jjwzyrd1m9917qz512fvde3n)) - 8. Handle Rate Limiting and Throttling Implement rate limiting and throttling to protect your API from abuse and ensure fair usage. Return appropriate error codes (e.g., 429 - Too Many Requests) when rate limits are exceeded, and provide guidance on how users can adjust their requests to comply with rate limits.

Test various scenarios, including valid requests, invalid requests, and edge cases, to identify and address potential issues.
