Incorrect value of Amount field QuickBooks SDK

The task is to pay invoices from deposites automatically for all customers. I create an application that will do everything when you click the button. I decided that it would be correct to create a customer payment that will pay for all open invoices. I work through qbXML and C# sdk. The XML query looks like this:

<?xml version="1.0" encoding="utf-8"?>
<?qbxml version="13.0"?>
<QBXML>
    <QBXMLMsgsRq onError="stopOnError">
        <ReceivePaymentAddRq>
            <ReceivePaymentAdd>
                <CustomerRef>
                    <FullName>#1 ASAP Transport Inc</FullName>
                </CustomerRef>
                <RefNumber>LS-2-39</RefNumber>
                <TotalAmount>1000.00</TotalAmount>
                <AppliedToTxnAdd>
                    <TxnID>399DB-[removed]</TxnID>
                    <SetCredit>
                        <CreditTxnID>39A[removed]</CreditTxnID>
                        <AppliedAmount>0.00</AppliedAmount>
                    </SetCredit>
                </AppliedToTxnAdd>
            </ReceivePaymentAdd>
        </ReceivePaymentAddRq>
    </QBXMLMsgsRq>
</QBXML>

Response:

<?xml version="1.0" ?>
<QBXML>
    <QBXMLMsgsRs>
        <ReceivePaymentAddRs statusCode="3210" statusSeverity="Error" statusMessage="The 
           &quot;receive payment total amount&quot; field has an invalid value &quot;1000.00&quot;.  
           QuickBooks error message: This field contains an invalid character." />
    </QBXMLMsgsRs>
</QBXML>

I tried changing the point to a comma, removing decimal numbers. Then error 3040: There was an error when converting the amount & quot;1000" in the field & quot; TotalAmount".

I also tried sending a similar xml example from the documentation, but ended up with the same error. When you try to add a Receive Payment via c#, the objects in the C# example have the same error numbers. There is a similar problem with other operations where I specify amounts (for example, creating an invoice or changing the amount in it)
