Most endpoints require HMAC-SHA256 signature authentication. The collection includes pre-request scripts that automatically:

• Generate timestamps
• Create query strings
• Calculate HMAC-SHA256 signatures
• Set authentication headers

The collection automatically handles signature generation for authenticated endpoints using pre-request scripts that:

1. Extract request parameters
2. Generate timestamp
3. Create signature string
4. Calculate HMAC-SHA256 hash
5. Set required headers

Please be aware of API rate limits and implement appropriate delays between requests when needed.

Check response status codes and error messages for troubleshooting. Common issues include:

• Invalid signatures
• Expired timestamps
• Missing required parameters
• Insufficient permissions
