Binance::API: can't connect to the exchange

Question

I'm an algo-trader and Perl fan. I want to create a client which connects to Binance Future Testnet and i decided to exploit the Binance API module developed for Perl.

Once the Binance::API module was installed (no errors or warnings occurred there) i dived into my script first lines of code as follows:

#!/bin/perl 

use Binance::API;

#API di Binance-Testnet
my $api = Binance::API->new(
    apiKey    => 'my api',
    secretKey => 'my secret key',
);
 
$api->account(); 
$api->exchange_info();

API KEY and SECRET KEY are taken from my Binance Future Testnet Account (freely available for all users), succesfully used via tradingview and its Pine script tool.

Unfortunatly i got the following error:

[Binance::API::Request::_exec] Unsuccessful request.
Status => 401,
Content => {"code":-2015,"msg":"Invalid API-key, IP, or permissions for action."} at C:/Strawberry/perl/site/lib/Binance/API/Request.pm line 107.
[Binance::API::Request::_exec] Unsuccessful request.
Status => 404,
Content => 404 Not found at C:/Strawberry/perl/site/lib/Binance/API/Request.pm line 107.

Any idea on what went wrong with this? I don't want to use Python or C++ as I love Perl and its versatility.

If you look at Binance::API source code, you can see this module developed for Spot market. not Futures. https://github.com/taskula/binance-perl-api/blob/master/lib/Binance/Constants.pm

BEGIN {
%constants = (
    BASE_URL => $ENV{BINANCE_API_BASE_URL} || 'https://api.binance.com', #this endpoint is for spot
    DEBUG    => $ENV{BINANCE_API_DEBUG}    || 0,
);
}

for Spot Testnet you can get API KEY from here: https://binance-docs.github.io/apidocs/spot/en/#enabling-accounts

I think you may get confused with spot and futures. There are 4 different base URL for different markets:

Spot Production site: https://api.binance.com
Spot Testnet site: https://testnet.binance.vision
Futures Production site: https://fapi.binance.com
Futures Testnet site: https://testnet.binancefuture.com
