Troubleshooting

Overview

Effective troubleshooting is essential for building reliable applications with the Nakisa API. This guide provides comprehensive strategies for identifying, diagnosing, and resolving common API issues.

Key Principles

  • Systematic Approach: Follow a structured debugging process

  • Proactive Monitoring: Implement logging and monitoring from the start

  • Graceful Degradation: Handle errors without breaking user experience

  • Documentation: Keep detailed records of issues and solutions

Common Error Types and Solutions

Authentication Errors

Error Code

Cause

Solution

Recovery

401 Unauthorized

Missing or invalid API key

Verify API key in x-api-key header

Refresh API key or contact support

403 Forbidden

Insufficient permissions

Check API key permissions and roles

Request elevated permissions

Rate Limiting and Throttling

Error Code

Cause

Solution

Recovery

429 Too Many Requests

Rate limit exceeded

Implement exponential backoff

Wait for rate limit reset

Resource and Data Errors

Error Code

Cause

Solution

Recovery

404 Not Found

Resource doesn’t exist

Verify endpoint URL and parameters

Check API documentation

400 Bad Request

Invalid request format

Validate request parameters

Fix request structure

422 Unprocessable Entity

Invalid data format

Check request body format

Validate against API schema

Server and Network Errors

Error Code

Cause

Solution

Recovery

500 Internal Server Error

Server-side error

Retry with exponential backoff

Contact support if persistent

502 Bad Gateway

Upstream server error

Retry after delay

Monitor service status

503 Service Unavailable

Service temporarily down

Implement circuit breaker

Wait for service restoration

Monitoring and Alerting

Key Metrics to Track

  • Response Times: Monitor API performance

  • Error Rates: Track failure percentages

  • Rate Limit Usage: Monitor API quota consumption

  • Authentication Failures: Track auth issues

  • Server Errors: Monitor 5xx errors

Best Practices

Error Handling

  1. Always Check Status Codes: Never assume success

  2. Implement Retry Logic: Use exponential backoff for transient errors

  3. Log Everything: Maintain detailed logs for debugging

  4. Handle Timeouts: Set appropriate timeout values

  5. Validate Responses: Check response structure and data types

Performance

  1. Use Connection Pooling: Reuse HTTP connections

  2. Implement Caching: Cache successful responses

  3. Monitor Rate Limits: Track API usage carefully

  4. Optimize Requests: Minimize payload size and request frequency

Security

  1. Secure API Keys: Never log or expose API keys

  2. Validate Input: Sanitize all request data

  3. Use HTTPS: Always use secure connections

  4. Implement Timeouts: Prevent hanging requests

Monitoring

  1. Track Key Metrics: Monitor response times, error rates, and usage

  2. Set Up Alerts: Get notified of issues immediately

  3. Log Strategically: Balance detail with performance

  4. Test Regularly: Verify API functionality periodically

Getting Help

Before Contacting Support

  1. Check Documentation: Verify API usage against documentation

  2. Test with Tools: Use Postman or cURL to isolate issues

  3. Review Logs: Analyze application and API logs

  4. Reproduce Issues: Create minimal test cases

When Contacting Support

Include the following information:

  • Error Details: Full error messages and stack traces

  • Request Information: URL, headers, and request body

  • Response Data: Status code and response body

  • Environment: SDK version, platform, and configuration

  • Steps to Reproduce: Clear steps to recreate the issue

  • Logs: Relevant application and API logs

Conclusion

Effective troubleshooting requires a systematic approach, proper tooling, and comprehensive monitoring. By implementing these patterns and best practices, you can quickly identify and resolve API issues while maintaining reliable application performance.
