PageSightError Handling
Best practices for handling errors in your API integrations.
Error Handling Principles
Key Principles
- • Always check response status: Don't assume success
- • Handle specific error types: Different errors need different handling
- • Provide user-friendly messages: Translate technical errors
- • Implement retry logic: For transient errors
- • Log errors appropriately: For debugging and monitoring
- • Fail gracefully: Don't crash your application

Error Types and Handling
Rate Limit Errors (429)
- • Check Retry-After header
- • Wait before retrying
- • Implement exponential backoff
- • Consider upgrading plan
Authentication Errors (401)
- • Verify API key is correct
- • Check Authorization header format
- • Don't retry - fix the issue first
- • Show user-friendly message
Client Errors (4xx)
- • Validate input parameters
- • Check error message for details
- • Don't retry - fix the request
- • Provide specific error feedback
Server Errors (5xx)
- • Retry with exponential backoff
- • Set maximum retry attempts
- • Log for monitoring
- • Show generic error to users
Best Practices
Do
- • Use try-catch blocks
- • Check response status codes
- • Handle specific error types
- • Implement retry logic for transient errors
- • Log errors for debugging
- • Provide user-friendly messages
- • Respect Retry-After headers
Don't
- • Ignore errors
- • Retry on all errors
- • Retry indefinitely
- • Show technical errors to users
- • Make requests without error handling
- • Ignore rate limit errors
- • Retry immediately on 429 errors
