Frequently Asked Questions

What causes Binance error code -2014?
Error -2014 occurs when your API key format is invalid, corrupted, or improperly formatted. This can happen due to copy-paste errors, key corruption, or using an outdated/deleted API key.
Will I lose my trading history after regenerating API keys?
No, regenerating API keys does not affect your trading history, account balance, or any other account data. Only the API access credentials change.
How do I prevent API key format errors in the future?
Always copy API keys directly from Binance without manual typing, store them securely, avoid editing the key strings, and regularly rotate keys for security. Use secure password managers for storage.
Can I use the same API key for multiple applications?
Yes, you can use one API key across multiple applications, but it's more secure to create separate keys for each application with specific permissions tailored to their needs.
What should I do if my API key keeps getting corrupted?
Check your storage method (avoid plain text files), ensure you're copying the complete key without extra characters, verify your application isn't modifying the key, and consider using a secure credential management system.
