first of all it is my first experience with SOAP Webservice, so I'm trying to understand how to interpret it. The first step that I did was to read the wsdl file, for do that I needed to insert the username and password that the webservice provider gave. The webservice looks like this:

I can interpret according to this file the following:
- service name: InformacionComercialWSService
- port name: InformacionComercial
- possible operations: consultaXml, consultaPlano and cambioPassword
So, according to the development environment of the webservice I need to pass this info as parameters: 'codigoInformacion':"1401", 'motivoConsulta':"24", 'numeroIdentificacion':"80775779", 'tipoIdentificacion':"1"
The following is the SOAP UI Request that works:
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inf="http://infocomercial.cifin.asobancaria.com">
<soapenv:Header/>
<soapenv:Body>
<inf:consultaXml soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<in0 xsi:type="dto:ParametrosConsultaDTO" xmlns:dto="http://dto.infocomercial.cifin.asobancaria.com">
<codigoInformacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">1401</codigoInformacion>
<motivoConsulta xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">24</motivoConsulta>
<numeroIdentificacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">80775779</numeroIdentificacion>
<tipoIdentificacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">1</tipoIdentificacion>
</in0>
</inf:consultaXml>
</soapenv:Body>
</soapenv:Envelope>
Additionally I need to insert the certification of the company to confirm the footprint of the request. So to do that I decided to implement a python development because is my main language. I found a library call Zeep that allows use it as a soap client. The webservice documentation says that the authentication should be Http Basic, it is the unique information I have.
So I install the requirements as follows:
python = "^3.8"
zeep = "^4.0.0"
After that, I needed to research information to code using Zeep, the result is this:
import requests
from requests import Session
from requests.auth import HTTPBasicAuth # or HTTPDigestAuth, or OAuth1, etc.
from zeep import Client
from zeep.transports import Transport
from zeep import xsd
session = Session()
session.cert = "XXXXXX/certificate.pem"
session.auth = HTTPBasicAuth("XXXXXX", "XXXX")
end_point= 'https://cifinpruebas.asobancaria.com/InformacionComercialWS/services/InformacionComercial?wsdl'
soap_client = Client(end_point,
transport=Transport(session=session), service_name="InformacionComercialWSService", port_name="InformacionComercial")
print("conexión establecida en :" + end_point)
request_data = {
'codigoInformacion':"1401",
'motivoConsulta':"24",
'numeroIdentificacion':"80775779",
'tipoIdentificacion':"1"
}
print(soap_client.service.consultaXml(**request_data))
I could solve many difficulties in the process, but I have been spend a lot of time in the following error that I don't understand how to solve it, and the webservice company is not supporting in coding because they only have information in Java and .Net. The error is:
Traceback (most recent call last):

I think, I'm not passing in the correct way the parameters, but I don't understand well the WSDL file, I was trying change the request for:
print(soap_client.service.consultaXml(**{'ParametrosConsultaDTO':request_data}))
but the error is like the same...

Following this code https://stackoverflow.com/a/50093489/2607773 I could collect:
{'InformacionComercialWSService': {'InformacionComercial': {'operations': {'cambioPassword': {'input': {'in0': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}}}},
'consultaPlano': {'input': {'in0': {'optional': False,
'type': {'codigoInformacion': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}},
'motivoConsulta': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}},
'numeroIdentificacion': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}},
'tipoIdentificacion': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}}}}}},
'consultaXml': {'input': {'in0': {'optional': False,
'type': {'codigoInformacion': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}},
'motivoConsulta': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}},
'numeroIdentificacion': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}},
'tipoIdentificacion': {'optional': False,
'type': {'_value_1': {'optional': False,
'type': 'String(value)'}}}}}}}}}}}
So I change the request_data for:
request_data = {
'in0': {
'codigoInformacion': {
'_value_1': {
'optional': False,
'type': "1401"
}
},
'motivoConsulta': {
'_value_1': {
'optional': False,
'type': "24"
}
},
'numeroIdentificacion': {
'_value_1': {
'optional': False,
'type': "80775779"
}
},
'tipoIdentificacion': {
'_value_1': {
'optional': False,
'type': "1"
}
}
}
}
But I received another error:

Another thing that I did was to use Factory objects as the documentation says at factory object zeep:
factory = soap_client.type_factory('ns0')
request = factory.ParametrosConsultaDTO(codigoInformacion="1401", motivoConsulta="24", numeroIdentificacion="80775779",
tipoIdentificacion="1")
print(request)
try:
print(soap_client.service.consultaXml(request))
except requests.exceptions.ConnectionError as e:
response = "Without response"
print(response)
but it shows another error:
urllib3.exceptions.NewConnectionError: <urllib3.connection.HTTPSConnection object at 0x7fb685c865b0>: Failed to establish a new connection: [Errno -2] Name or service not known
I verified that .pem certificate still available and it works with SOAP UI.
If someone can help me, I'm very grateful, maybe I'm near to solve it.
Postdata: Sorry if my english is not very good.
