Binance API Error Code -1022: How to Fix It

Q: What causes Binance error code -1022?

Error -1022 occurs when the HMAC SHA256 signature in your API request is invalid. Common causes include incorrect API keys, wrong timestamp format, improper query string construction, or system clock synchronization issues.

Q: How do I fix timestamp issues with Binance API?

Ensure your system clock is synchronized with internet time and use Unix timestamp in milliseconds format. The timestamp should be current (within 5000ms of server time) and included in the signature calculation.

Q: Can I test Binance API signatures without real trading?

Yes, use Binance Testnet with testnet API keys to test your signature implementation safely. This allows you to debug without affecting real funds or trading positions.

Q: What programming languages work with Binance API?

Binance API works with any language that supports HMAC SHA256 encryption, including Python, JavaScript, Java, C#, PHP, and Go. Many languages have official or community libraries that simplify signature generation.

Q: Why does my Binance API signature work sometimes but not always?

Intermittent signature failures are usually caused by timestamp drift or system clock synchronization issues. Ensure your system time stays synchronized and generate fresh timestamps for each request.

Abstract

Binance error code -1022 appears when your API request signature is invalid, typically due to incorrect HMAC SHA256 encryption or timestamp issues. This error prevents your trading bot or application from executing orders and accessing your account data.
