Signing Binance Withdrawal Requests and Diagnosing Parameter Errors

Summary

This troubleshooting note asks how to submit a Binance withdrawal request through an API. It focuses on adding a timestamp and generating an HMAC-SHA256 signature over request parameters. The author tries sending the parameters and signature in the request body, then in the query string, and reports different API responses: an empty-payload error, an invalid signature-format error, and a signature-validation error when the signature is omitted.

The examples illustrate that request placement and signature construction both matter when debugging authenticated exchange calls. However, the note does not reach a working solution or establish the exact withdrawal endpoint requirements. The initial query-string signing example concerns a different kind of request, so it does not by itself verify the correct withdrawal payload, encoding, parameter ordering, or authentication procedure. The reported failures are evidence of unsuccessful attempts rather than a validated method. This is API integration troubleshooting, not a trading strategy, and the request should be checked against the applicable exchange documentation and current endpoint behavior.

Key ideas

• The author attempts to sign withdrawal parameters with HMAC-SHA256 and include a timestamp.
• Putting parameters in the body produces an empty-payload error in the reported attempt.
• Moving the parameters to the query string leads to a signature-format error, while omitting the signature fails validation.
• The note does not demonstrate a successful withdrawal request or confirm the endpoint’s exact requirements.
• The example signing a different request type does not establish the correct withdrawal procedure.
