Signature for this request is not valid error on withdrawal operation

[PaulMuller]

few days ago start to receive this error when try to withdraw from binance.

Solved by manyally replace signature from URL into form body.

const signedRequest = ( url, data = {}, callback, method = 'GET', noDataInSignature = false ) => {
...
 if ( method === 'POST' ) {
            let opt = reqObjPOST(
                url,
                data,
                method,
                Binance.options.APIKEY
            );
            opt.form.signature = signature
            // + '?signature=' + signature
            // let opt = reqObjPOST(
            //     url + '?signature=' + signature,
            //     data,
            //     method,
            //     Binance.options.APIKEY
            // );
            // console.log(opt)
            proxyRequest( opt, callback );

thank you for sharing your solution, curious how the problem is only on withdraw. cheers!

This did not break anything else? Nice improvement, thanks again.

if ( method === 'POST' ) {
    let opt = reqObjPOST(
        url,
        data,
        method,
        Binance.options.APIKEY
    );
    opt.form.signature = signature;
    proxyRequest( opt, callback );
}

Also getting this error with marketSell. This change doesn't fix it for me.

Note: I had to change the URLs as I'm using binance.us, not sure if that has any bearing here.

If possible, please switch to

POST /sapi/v1/capital/withdraw/apply

https://binance-docs.github.io/apidocs/spot/en/#withdraw-sapi

I have the same problem, this worked for me, but I wonder when they will upload the fix to npm @jaggedsoft

[DeveloperAriana]

hola @DeveloperAriana, ¿puedes describir cómo lo arreglaste ? Apliqué el cambio de código pero no funcionó para mí.

Hello, I made the same modification that I comment @PaulMuller , I went to the node-modules folder of my project, specifically node-binance-api and I modified the file called node-binance-api.js. Attached image of how the file is finally

If this still doesn't work for you, make sure your keys are correct

@DeveloperAriana, i did exactly same and my keys are true but not worked :(
if i change like this withdraw fails and even trade fails.
@jaggedsoft

This fix work for me:

 opt.form.signature = signature;

Current version .withdraw has an error with signature.

"node-binance-api": "^0.11.6",
