        string $secret,
        string $requestBody,
        string $httpUri = null,
        string $httpMethod = 'POST',
        string $signatureVersion = 'v1'

        }

        return $signature == hash('sha256', $sourceString);
    }
}

However, your documentation says this: https://developers.hubspot.com/docs/api/webhooks/validating-requests. You'd need to add a timestamp to the signature (let's call it $xHubSpotSignaturev3). For the record, it should be this

$sourceString = $httpMethod . $httpUri . $requestBody . $xHubSpotRequestTimestamp;
$calculatedSignature = base64_encode(hash_hmac('sha256', $sourceString, $secret, true)); // true = binary
return hash_equals($calculatedSignature, $signature);

I just found https://github.com/HubSpot/hubspot-api-php/blob/master/lib/Utils/Signature.php by going through your Unit Tests. I missed that the one above is marked as @deprecated.
