Currently, develop some code for insert record into res.partner(Contact) by calling Odoo API one by one using loop.

But, i want to insert all record by single call of Odoo API 

Is this possible ?

please have a look my existing code, implements for c#

foreach (var loCustomer in loCustomeresList)

{

    if (!string.IsNullOrEmpty(loCustomer.lsName))

    {

        loRecordPairCompany = new XmlRpcStruct();

        loRecordPairCompany.Add("name", loCustomer.lsCustomerID);

        loRecordPairCompany.Add("Phone_Number", loCustomer.lsPhoneNumber);

        loRecordPairCompany.Add("email", loCustomer.lsEmail);

        loRecordPairCompany.Add("website", loCustomer.lsWebsite);

        loRecordPairCompany.Add("property_payment_term_id", loCustomer.liCustomerPaymentTerm);

        loRecordPairCompany.Add("is_company", true);

        int liCompanyID = loRpcRecord.create(Common.lsDbName, liUserid, Common.lsDbPassword, "res.partner", "create", loRecordPairCompany);

}

}
