APIs are the backbone of modern software development, enabling seamless communication between systems. To ensure security, performance, and efficiency, developers rely on a variety of tools. Below is a categorized breakdown of essential API tools.

Protection

  • Cloudflare – Mitigates DDoS attacks and secures APIs.
  • AWS WAF – Protects APIs from common web exploits.
  • Azure Firewall – Provides threat protection for API endpoints.
  • Google Cloud Armor – Defends against Layer 7 attacks.

Command Example (AWS WAF):

aws wafv2 create-web-acl --name APISecurityACL --scope REGIONAL --default-action "Block={}" --visibility-config "SampledRequestsEnabled=true, CloudWatchMetricsEnabled=true"

Monitoring

  • New Relic – Tracks API performance and errors.
  • Datadog – Monitors API latency and uptime.
  • Splunk – Logs and analyzes API traffic.

Command Example (Splunk Log Analysis):

splunk search "source=api_logs status=500 | stats count by endpoint"

Deployment Management

  • AWS API Gateway – Manages API versioning and deployment.
  • Kong – Open-source API gateway for microservices.

Command Example (Kong API Deployment):

curl -i -X POST --url http://localhost:8001/services/ --data 'name=example-service' --data 'url=http://example.com'

Testing

  • Postman – Automated API testing.
  • JMeter – Load testing for APIs.

Command Example (Postman CLI):

newman run api_tests.json --reporters cli,json

Security

  • OWASP ZAP – Scans APIs for vulnerabilities.
  • Burp Suite – Penetration testing for APIs.

Command Example (OWASP ZAP Scan):

docker run -v $(pwd):/zap/wrk/:rw -t owasp/zap2docker zap-api-scan.py -t http://api.example.com -f openapi

Code Generation

  • Swagger Codegen – Generates API clients from OpenAPI specs.

Command Example (Swagger Codegen):

java -jar swagger-codegen-cli.jar generate -i api-spec.yaml -l python -o /output

Design & Development

  • Swagger (OpenAPI) – API documentation and design.
  • Postman Mock Server – Simulates API responses.

Command Example (OpenAPI Generation):

swagger-cli bundle api-spec.yaml --outfile bundled-spec.json

You Should Know:

  • API Security Best Practices:
  • Always use HTTPS (openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365).
  • Implement rate limiting (nginx -t -c /etc/nginx/nginx.conf).
  • Use JWT for authentication (openssl rand -hex 32).

  • Linux Commands for API Debugging:

    curl -v -X GET https://api.example.com/users 
tcpdump -i eth0 port 443 -w api_traffic.pcap 
netstat -tuln | grep 8080

  • Windows API Troubleshooting:

    Test-NetConnection -ComputerName api.example.com -Port 443 
Get-Process -Id (Get-NetTCPConnection -LocalPort 8080).OwningProcess

What Undercode Say:

APIs are critical but vulnerable. Proper tooling, monitoring, and security hardening are essential. Automation (CI/CD pipelines, automated scans) reduces risks.

Expected Output:

  • Secure API endpoints with WAF and OWASP ZAP.
  • Monitor performance using Datadog/Splunk.
  • Automate testing with Postman/JMeter.

Prediction:

API attacks will rise; AI-driven security tools (like DeepCode) will become standard. Zero-trust API gateways will dominate.
