Ethereum: How can I solve msg: ‘Signature for this request is not valid.’ from binance API?
The resolution of the «signature for this request is not valid» error in API Binance
As you live, one of the most common errors when interacting with the binance API is to receive a «signature for this request is not an error». This error generally occurs due to an unlikely or expired signature used to authenticate API requests.
In this article, we will explore the possible reasons for this error and provide steps to resolve it using the secret key and the horoditing approach.
Why should the signature be updated?
When you send a request to the Binance API, your customer (usually a program) includes a unique identifier in the authentication header. This is called a «signature» or a «token». The binance API uses this signature to authenticate your requests and check that they come from an authorized source.
How to update the signature:
To resolve the error «signature for this request is not valid», you must update the signature using the following approach:
- Get the current exploitation : Get the current UNIX horoding in seconds since January 1, 1970.
`Javascript
Const Now = math.floor (date.now () / 1000);
'
- Calculate the new signature : Use theHMAC
library to generate a new signature using your secret key and updated timeing.
Javascript
Const hmac = require ('crypto'). Createhmac ('sha256', 'Your_secret_key');
hmac.update (now.tostring ());
Const signature = hmac.digest ('hex');
'
- Update the API
request: replace thesigning of the new by the new.
Code example:
Here is an example of code extract to demonstrate this process:
`Javascript
Const Bnb = require ('Binance-dep');
// Configure your API Binance identification information and your secret key
Const client = new bnb.client ({
Apirversion: 'V2',
Accesstoken: "Your_access_token",
});
// Get the current horoding
Const Now = math.floor (date.now () / 1000);
// Calculate the new signature
Const hmac = require ('crypto'). Createhmac ('SHA256', Process.Ev.Secret_Key);
hmac.update (now.tostring ());
Const signature = hmac.digest ('hex');
// Update the API request
client.authheader ({
"Standard content": "application / json",
'Authorization':Bearer $ {Customer.Getaccesstoken ()},
"Signature": signature,
});
` ‘
Best practices:
To prevent this error in the future:
- Use a secure and up -to -date secret key.
- Keep your secret confidential key, as it can be used to authenticate API requests.
- Update your secret key regularly and your horoditing to ensure continuous authentication.
By following these steps, you should be able to resolve the «signature for this request is not a» valid «error during the interaction with the binance API. Happy coding!
