Checklist for API Compliance in Backend Systems

API compliance ensures secure, reliable, and regulation-aligned backend systems. Here's a quick summary of what you need to know:

• Security: Use strong access control (MFA, RBAC), encrypt data (TLS 1.3, AES-256), and manage API keys/tokens securely.
• Data Management: Follow privacy laws like GDPR/CCPA, validate inputs, and automate data cleanup.
• Performance: Track uptime (99.9%), response time (<115ms), and use version control for seamless updates.
• Documentation: Provide clear API specs, error handling, and testing procedures.

Quick Tips:

1. Regularly audit APIs for vulnerabilities.
2. Monitor suspicious activity with automated alerts.
3. Keep detailed logs for compliance and troubleshooting.

API Security for PCI Compliance (Data Security Standard)

Security Requirements

Protecting data, preventing unauthorized access, and maintaining system integrity are key goals of security measures.

Access Control Setup

A strong access control system combines authentication and authorization. Here are the essential components:

Control Layer	Required Components	Compliance Standards
Authentication	MFA, SSO, Biometrics	NIST 800-63B
Authorization	RBAC, ABAC	ISO/IEC 27001
Session Management	Token-based, JWT	OWASP Top 10

To enhance security, include role-based rate limiting, monitor user request patterns, and automatically end inactive sessions after 15–30 minutes. These measures, combined with secure storage and encryption protocols, create a strong defense for APIs.

Data Security Standards

Securing data involves encryption and proper storage methods. Key practices include:

• Transport Layer Security (TLS): Use TLS 1.3 or higher for all API communications.
• Data Encryption: Protect data at rest with AES-256 encryption.
• Key Management: Rotate encryption keys every 90 days.
• Certificate Management: Regularly monitor SSL/TLS certificate expiration dates.

Store sensitive credentials such as API keys and tokens in secure locations like key vaults or HSMs. Avoid embedding these credentials in code or configuration files.

API Security Management

Strengthen API security by managing keys, tokens, and request validation effectively.

1. API Key Management

• Rotate API keys every 60 days.
• Assign unique keys for each environment.
• Immediately revoke compromised keys.

2. Token Security

• Set access tokens to expire within 1 hour.
• Use refresh tokens with a 14-day validity period.
• Ensure a system is in place for token revocation.

3. Request Validation

• Sanitize all API inputs to prevent injection attacks.
• Validate request payload schemas to ensure proper formatting.
• Verify the content-type of requests.
• Restrict request sizes to a maximum of 10MB.

Continuously monitor API endpoints for suspicious activity, such as repeated failed login attempts or unusual traffic spikes. Set up automated alerts for such events, and conduct quarterly security audits to identify and fix vulnerabilities. These proactive steps help maintain a secure API environment.

Data Management Standards

Managing data effectively is essential for ensuring your APIs comply with security, accuracy, and regulatory requirements.

Privacy Rules

Handling sensitive data requires strict controls. Use the following guidelines to align with privacy regulations:

Privacy Requirement	Implementation Standard	Validation Method
Data Collection	Obtain explicit user consent	Use automated consent tracking
Data Access	Apply role-based permissions	Monitor access logs
Data Sharing	Use encrypted transfer protocols	Verify transfers
Data Retention	Enforce time-limited storage	Automate data cleanup

Set up detailed role-based access controls and use automated data classification tools to safeguard sensitive information. Ensure storage protocols are configured to provide secure and efficient data management.

Data Storage Rules

• Retention Requirements
  Keep data only for the duration required by regulations, and use automated systems to delete it afterward.
• Storage Architecture
  Build storage systems with redundancy and encryption. Separate data into tiers based on sensitivity, using stronger encryption for more sensitive information.
• Backup Requirements
  Encrypt backups, restrict access, and regularly verify their integrity to ensure they can be relied upon during system failures.

Data Validation Methods

Accurate data and protection against malicious inputs require robust validation processes. For example, OilpriceAPI ensures data accuracy with 5-minute refresh intervals, 99.9% uptime, and real-time checks.

Key validation techniques include:

Validation Type	Implementation Method	Frequency
Input Sanitization	Use regular expression filters	Every request
Schema Validation	Check JSON/XML schemas	Every payload
Data Type Verification	Enforce strong data typing	Ongoing
Range Validation	Define value boundaries	Every update

To further enhance data integrity, deploy automated monitoring tools that flag anomalies or unusual patterns. Alerts for unexpected values allow you to quickly address potential issues and maintain system security.

System Performance Standards

Effective monitoring and management are key to maintaining consistent API performance, ensuring it meets industry standards and provides dependable service.

Version Control Requirements

Follow semantic versioning practices by documenting all changes, including breaking updates, and maintaining backward compatibility with every release.

To make these practices effective, consistent system monitoring is crucial to track and address performance issues promptly.

System Monitoring Setup

Defining clear performance benchmarks helps ensure API compliance and aligns with established security and data standards. Focus on monitoring these key metrics:

Monitoring Area	Key Metric	Alert Threshold
Response Time	Average latency	Above 115ms
System Uptime	Service availability	Below 99.9%

OilpriceAPI’s metrics serve as a practical example of achievable API reliability targets.

Performance Management

Managing performance effectively involves handling traffic surges and ensuring the system remains responsive. Strategies like rate limiting are particularly useful. For example, OilpriceAPI employs tiered rate limiting in its usage plans to balance request distribution during high-demand periods.

Documentation Requirements

Clear and precise documentation is critical for ensuring API compliance. It not only helps developers implement APIs correctly but also aligns with necessary compliance standards.

API Documentation Standards

Comprehensive API documentation is key to successful integration. Here are the essential elements to include:

Documentation Element	Details	Purpose
Authentication Methods	OAuth 2.0, API keys, token handling	Verifies security
Endpoint Specifications	Complete URL structures, HTTP methods	Ensures integration accuracy
Data Formats	Request/response schemas, field validations	Maintains data integrity
Error Handling	Status codes, error messages, recovery steps	Improves reliability
Rate Limits	Request quotas, throttling rules	Manages performance

Testing Requirements

Once documentation is in place, thorough testing is essential to confirm API compliance. Here’s what to focus on:

• Unit Testing: Validate individual endpoints to ensure they function as intended.
• Integration Testing: Check how the API interacts with the entire system.
• Compliance Testing: Ensure the API meets all required standards.
• Security Testing: Identify and address potential vulnerabilities.
• Performance Testing: Evaluate how the API handles load and stress.

Keep detailed audit logs for every test suite, and automate testing during deployments to catch issues early.

Change Tracking Methods

Accurate record-keeping is the final step in maintaining compliance. Track all updates and modifications to verify adherence to standards. Key elements to document include:

• Version Control Documentation: Log every code change with clear commit messages that explain what was modified and why it matters for compliance.
• Configuration Management: Record updates to system settings, such as authentication methods, rate limits, and data handling rules.
• Audit Trail Maintenance: Maintain logs for system access, data changes, API version updates, and any compliance-related incidents.
