** Error of the Binance API “signature of what
As you feel, one of the most common errors when communication with the Binance API receives a “signature for this request” error. This error generally results from an inappropriate or expired signature used to confirm API requests.
In this article, we will study the possible causes of this error and provide actions to resolve it using a secret key and a temporal brand method.
Why should the signature be updated?
When you send a request to Binance API, your customer authentication header (usually program) has a unique identifier. This is called “signature” or “token”. Binance API uses this signature to confirm your requests and check that they come from an authorized source.
How to update the signature:
To resolve the error “the signature of this request is not valid”, you must update the signature using the following method:
- Get the current talent of time
: Get the current UNIX Time brand in seconds since 1970. January 1
`Javascript
Const Now = math.floor (data.now () / 1000);
'
2
Javascript
Const hmac = required ('crypto'). Createhmac ('sha256', 'Your_secret_key');
hmac.update (now.tostrin ());
Cons signature = hmac.digest ('hex');
'
- Update the API request: modify the new new signature header.
Code example:
Here is an example of the code fragment to show this process:
Javascript
Const Bnb = require ('Binance-dep');
// Define your API Binance identification information and a secret key
Const customer = new bnb.client ({{{{{{{{{{{{{{{{{
Insertion: V2,
Accesstoken: your_access_token,
});
// Get the current time label of time
Const Now = math.floor (data.now () / 1000);
// Calculate the new signature
Const hmac = required ('crypto'). Createhmac ('SHA256', Process.Ev.Secret_Key);
hmac.update (now.tostrin ());
Cons signature = hmac.digest ('hex');
// Update the API request
Client.autheader ({{{{{
Content type: application / json,
"Authorization": "nearly {client.GetaccessSTOKEN ()}
“Signature”: signature,
});
“ ‘
Best practices:
To avoid this error in the future:
- Use a safe secret key and the last.
- Keep your secret confidential key because it can be used to confirm API requests.
- Update your secret key and your time tag regularly to ensure continuous authentication.
When you perform these steps, you should be able to resolve the “signature of this request” when you interact with the binance API. Happy coding!
