Always check HTTP status code before processing response +2. Implement comprehensive error logging +3. Provide user-friendly error messages +4. Use exponential backoff for retry mechanisms +5. Handle network and timeout errors gracefully + +### Example Error Handling (Pseudo-code) +```javascript +async function apiRequest(endpoint) { + try { + const response = await fetch(endpoint); + + if (!response.ok) { + const errorBody = await response.json(); + + switch (response.status) { + case 400: + throw new ValidationError(errorBody.error.message); + case 401: + handleUnauthorizedError(); + break; + case 500: + logServerError(errorBody); + break; + default: + handleGenericError(errorBody); + } + } + + return response.json(); + } catch (error) { + // Implement comprehensive error handling + console.error('API Request Failed:', error); + throw error; + } +} +``` + +### Retry Strategy Example +```javascript +async function retryRequest(fn, maxRetries = 3) { + let retries = 0; + + while (retries < maxRetries) { + try { + return await fn(); + } catch (error) { + if (error.status >= 500 || error.status === 429) { + const delay = Math.pow(2, retries) * 1000; + await new Promise(resolve => setTimeout(resolve, delay)); + retries++; + } else { + throw error; + } + } + } + + throw new Error('Max retries exceeded'); +} +``` + +### Monitoring and Logging +- Implement comprehensive error logging +- Use structured logging with error codes +- Monitor API error rates and patterns +- Set up alerts for recurring error conditions + +### Contact and Support +For persistent issues or unusual error patterns, contact support at support@example.com with: +- Exact error message +- HTTP status code +- Request details +- Reproduction steps \ No newline at end of file
