Issues Formatting a SOAP API with Savon gem

I was terrified this day would come.. dealing with SOAP API's...

This is a whole new realm for me, Ive done some digging with the SAVON gem but i cant seem to structure my call..

Essentially what I am trying to do is the following:

Step 1: Call the API to retrieve the LatestCallerVersion (API Version)

Step 2: Take the LatestCallerVersion and send a second request to the validation API to see if my customers are in a valid service area.

This is what I've come up with (but it crashes and burns hard)

caller_client = Savon.client(
  wsdl: 'https://alarmadmin.alarm.com/webservices/CustomerManagement.asmx?WSDL '\
)
caller_response = caller_client.call(
  :authentication,
  message: {
      user: 'xxxxxx',
      password: 'xxxxxx',
      two_factor_device_id: 'xxxxxx'
  },
  :body,
  message: {
      :get_latest_caller_version
  }
)

Here is the SOAP request & response Doc for the GetLatestCaller call

I am brand new to SOAP Any assistance here would be greatly appreciated. Please let me know if anything further is needed.

kindly use SOAP UI to check for the Request definition. On loading the the WSDL file in SOAP UI, I am able to get the following. Loading to SOAP UI

After that it becomes relatively easy to follow along. It seems all the operations has the same header, so I will go and create a client that looks like

caller_client = Savon.client(
          wsdl: 'https://alarmadmin.alarm.com/webservices/CustomerManagement.asmx?WSDL',
          env_namespace: :soapenv,
          namespace_identifier: :web,
          soap_header: {
            'web:Authentication': {
              'web:User': 'xxxx',
              'web:Password': 'xxxxx',
              'web:TwoFactorDeviceId': 'xxx'
            }
          })

And after that calling the individual operation becomes

caller_client.call(:get_latest_caller_version)

If you want to list all the possible operations, you can use

caller_client.operations

If you want to pass message to individual operation, use the following format

   caller_client.call(:get_modem_serial_from_iccid, message: { iccid: 'xxxx' })
