Saving XML Data from Endpoint to my database

Question

I am trying to pass from a "POST" endpoint that contains data in XML format to my model class then save the same to my database.

It is possible for me to save the data when the XML is in the format below:

                            <NCBAPaymentNotificationRequest>  
                                            <User>USER</User>  
                                            <Password>pass</Password>  
                            <HashVal>NzIwNGE3MzI5YmU5MTg3ZTUwZTQ1YmRjMjA0NDc2MjUyODQ2MmQ1ODIwZTIyYzNkNDk0NTBjNjUwZTgwYmM2Yw==</HashVal>  
                                            <TransType>999</TransType>  
                                            <TransID>FTC221024YAWQ</TransID>  
                                            <TransTime>2210241702</TransTime>  
                                            <TransAmount>1.00</TransAmount>  
                                            <AccountNr>6592460859</AccountNr>  
                                            <Narrative>Test</Narrative>  
                                            <PhoneNr>66666</PhoneNr>  
                                            <CustomerName>Customer 1</CustomerName>  
                                            <Status>SUCCESS</Status>  
                            </NCBAPaymentNotificationRequest>  

However, I want it saved when the XML is in the format below. It is at this point that I am facing issues:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">  
            <soapenv:Header/>  
            <soapenv:Body>  
                            <NCBAPaymentNotificationRequest>  
                                            <User>USER</User>  
                                            <Password>pass</Password>  
                            <HashVal>NzIwNGE3MzI5YmU5MTg3ZTUwZTQ1YmRjMjA0NDc2MjUyODQ2MmQ1ODIwZTIyYzNkNDk0NTBjNjUwZTgwYmM2Yw==</HashVal>  
                                            <TransType>999</TransType>  
                                            <TransID>FTC221024YAWQ</TransID>  
                                            <TransTime>2210241702</TransTime>  
                                            <TransAmount>1.00</TransAmount>  
                                            <AccountNr>6592460859</AccountNr>  
                                            <Narrative>Test</Narrative>  
                                            <PhoneNr>66666</PhoneNr>  
                                            <CustomerName>Customer 1</CustomerName>  
                                            <Status>SUCCESS</Status>  
                            </NCBAPaymentNotificationRequest>  
            </soapenv:Body>  
</soapenv:Envelope>  

Below is my Controller Code:

        [Consumes("application/xml")]  
        [Produces("application/xml")]  
        [HttpPost]  
        public async Task<NCBAPaymentNotificationRequest> Post([FromBody] NCBAPaymentNotificationRequest value)  
        {  
            value.User = value.User;  
            value.Password = value.Password;  
            value.HashVal = value.HashVal;  
            value.TransType = value.TransType;  
            value.TransID = value.TransID;  
            value.TransTime = value.TransTime;  
            value.TransAmount = value.TransAmount;  
            value.AccountNr = value.AccountNr;  
            value.Narrative = value.Narrative;  
            value.PhoneNr = value.PhoneNr;  
            value.CustomerName = value.CustomerName;  
            value.Status = value.Status;  
  
            int createdId = mpesaRepository.Add(value);  
            if (createdId > 0)  
            {  
                value.ID = createdId;  
            }  
            return value;  
        }
