How do I approach debugging an unfamiliar or undocumented Binance Futures error code that I encounter?

If you encounter an unfamiliar or undocumented error code, first re-check the latest official Binance Futures API documentation. Then, isolate the exact API call and parameters that triggered the error. Review recent changes in your code, network connectivity, or Binance system status. Collect the full error response, including any accompanying message. If the issue persists, the most effective approach is to contact Binance Support directly, providing them with all available details: the full error code and message, the endpoint called, request parameters, and your API key (if safe to disclose or describe its permissions).
