Hello @mehrdadphp ,

I saw that response from Binance when my API key/secret pair was no longer valid.

Best.

tanks @Marc008 for answer

It's strange to me that the rest of the methods work well, like ‍‍‍‍deposit , withdrawaHistory and ...

just for withdraw problem .
with key/secret use nodejs and test withdraw Worked well

Same here. Everything else works except withdrawal.

not work withdrawal :
{"msg":"Signature for this request is not valid.","success":false}

Same here, and yes my API details are valid and correct (I just created and it's working for other functions).

There's something wrong with the withdraw function only.

Did anyone figure it out yet?

Does it have anything to do with the ca.pem file?

Any clues appreciated.

Thanks

This problem just started occurring for us. GetBalance, MarketBuy and MarketSell all work fine.

Only Withdraw is giving us:
signedRequest error: {"msg":"Signature for this request is not valid.","success":false}

Anyone know why this would start happening all of a sudden?

The default name API Withdraw with space caused this problem.

# this should work
$response = $api->withdraw($asset, $address, $amount, null, 'my_address');

Reason:

In this name parameter, space has to be encoded into %20, but now i think it's encoded into +, which cause signature invalid.

Thank you @2pd! This solved the problem. I'd suggest just replacing the space in the default "API Withdraw" with an underscore.
