Solving the error “Signature for this request is not valid” in Binance API
As you face, one of the most common errors when you interact with the Binance API is to receive a “signature for this request is not valid”. This error usually occurs due to an invalid or expired signature used to authenticate API applications.
In this article, we will explore the possible reasons behind this error and provide steps to solve it using the secret approach of the keys and time time.
Why should the signature be updated?
When submitting a request to the Binance API, your customer (usually a program) includes a unique identifier in the authentication header. This is called “signature” or “token”. The Binance API uses this signature to authenticate your requests and check if they come from an authorized source.
How to update the signature:
To solve the error “Signature for this request is not valid”, you must update the signature using the following approach:
- Get current Timestamp : Get the current Timestamp Unix in seconds from January 1, 1970.
`JavaScript
const now = math.floor (data.now () / 1000);
- Calculate the new signature : Use theHmac
library to generate a new signature using your secret key and updated Timestam.
JavaScript
Const Hmac = requires ('crypto'). Createhmac ('Sha256', 'your_secret_key');
Hmac.Update (now.tostring ());
const -semnature = Hmac.digest ('hex');
- Update the api request : Replace the "Signature" header existing with the new one.
Code for example:
Here is an example of a code fragment to demonstrate this process:
JavaScript
const bnb = requires ('binance-api');
// configure -Va API Binance credentials and secret key
CON CUSTOM = New BNB.Client ({
Apiversity: 'V2',
Accessoken: "your_access_token",
});
// get the current timestammp
const now = math.floor (data.now () / 1000);
// Calculate the new signature
Const Hmac = requires ('crypto'). Createhmac ('Sha256', process.env.secret_key);
Hmac.Update (now.tostring ());
const -semnature = Hmac.digest ('hex');
// update the API request
Customer.AUTHHHEADER ({
"Type of content": "app/json",
"Authorization":bearer $ {client.getaccesstoken ()},
"Signature": signature,
});
`
best practices:
To prevent this error in the future:
- Use a secure and updated secret key.
- Keep the secret confidential key because it can be used to authenticate API applications.
- Update the secret key regularly to ensure continuous authentication.
Following these steps, you should be able to solve the error “Signature for this request is not valid” when you interact with Binance API. Happy coding!
