Integration Strategies and Best Practices

Authentication and Authorization: Ensure that your API key is securely stored and not exposed in client-side code. Use environment variables or secure vaults for sensitive information.
Rate Limiting and Quota Management: Be aware of your subscription plan's rate limits. Implement caching strategies to minimize unnecessary API calls and optimize performance.
Error Handling and Recovery: Implement robust error handling to manage API response errors gracefully. Consider retry mechanisms for transient errors.
Data Validation and Sanitization: Always validate and sanitize user inputs to prevent injection attacks and ensure data integrity.
Performance Optimization: Use asynchronous calls to improve the responsiveness of your application. Consider batching requests where applicable to reduce latency.
