1. **Rate Limits**
   •	Respect Rate Limits: The API allows up to 1000 requests per 5 minutes. Ensure there is a small delay between requests to avoid exceeding this limit.
   •	Avoid Overloading: Implement rate-limiting logic in your application to manage the frequency of requests and prevent throttling.
2. **Incremental Data Sync**
   •	Send Only Changes: When synchronizing data with the API, send only updated or changed information. Avoid sending the entire dataset unless explicitly required.
   •	Optimize Payloads: Use filters and data-specific endpoints to minimize the size of requests and improve performance.
3. **Error Handling and Monitoring**
   	•	Handle Errors Gracefully:
   	•	Implement retry mechanisms with exponential backoff for temporary errors (e.g., rate limits or timeouts).
   	•	Log and address error responses like 4xx (client errors) and 5xx (server errors) appropriately.
   	•	Monitor API Usage:
   	•	Regularly monitor your API interactions to identify issues early.
   	•	Log all API requests and responses, excluding sensitive information, for debugging and performance analysis
