Hi!

I’m new in Soap and I’m trying to connect to a Web Service and it trows me the error “Access Denied”.  
What this particular web service required is some credentials to be able to use it.  
I’ve manage to do in Ignition the script to get the credentials and it works fine. I use this credentials to test if it work in the program SoapUI and it gives me as a response the correct value that I’m looking for, but in Ignition gives me the “Access Denied” error, using the same credentials.

These are the WSDL I use:

- To get the credentials (token and sign): “[https://wsaahomo.afip.gov.ar/ws/services/LoginCms?wsdl](https://wsaahomo.afip.gov.ar/ws/services/LoginCms?wsdl)”
- To get access to the specific web service I’m trying to connect: “[https://fwshomo.afip.gov.ar/wsctg/services/CTGService\_v3.0?wsdl](https://fwshomo.afip.gov.ar/wsctg/services/CTGService_v3.0?wsdl)”

In this last one, the method I want it’s called “consultarCTGActivosPorPatente”

I do the following in a button in Ignition:

from suds.client import Client  
from xml.dom.minidom import parseString  
client = Client(“[https://fwshomo.afip.gov.ar/wsctg/services/CTGService\_v3.0?wsdl](https://fwshomo.afip.gov.ar/wsctg/services/CTGService_v3.0?wsdl)”)

ConsultaCTGActivo = client.service.consultarCTGActivosPorPatente(token,sign,CUIT,patente)

Here is the full error:

A quick way to get this set up is to use the Sepasoft Web Service module. SUDS is mostly deprecated and is not really supported very well. The Web Service module allows for rapid implementation of SOAP and RESTful interfaces.

The error returned says "Access denied, token or firm are null". The Client constructor requires more parameters in this case. The first parameter should be the wsdl url and then username and password:

```auto
from suds.client import Client
client = Client(wsdl_url, username="your_username", password="the_password")

```

Yes, the username and password are the token and sign values. Thank you!!!

The problem is when I try to invoke a method of that client.  
The structure should be the following in (xml format):

```auto
**<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"**
 **xmlns:ctg="http://impl.service.wsctg.afip.gov.ar/CTGService_v2.0/">**
 **<soapenv:Header/>**
 **<soapenv:Body>**
 **<ctg:consultarCTGActivosPorPatente>**
 **<request>**
 **<auth>**
 **<token>?</token>**
 **<sign>?</sign>**
 **<cuitRepresentado>?</cuitRepresentado>**
 **</auth>**
 **<patente>?</patente>**
 **</request>**
 **</ctg:consultarCTGActivosPorPatente>**
 **</soapenv:Body>**
 **</soapenv:Envelope>**

```

Replacing the "?" for actual values;  
token=username, sign=password, cuitRepresentado=this is a personal information of the programmer that use this web service, and patente=is the license plate of a car.

When using this method, I put:

ConsultaCTGActivo = client.service.consultarCTGActivosPorPatente(username=token, password=sign,cuit=CUIT,patente=patente)  
and it trows me the same error as before.

The following is a print of the client you told me

I need to use the consultarCTGActivosPorPatente(consultarCTGActivosPorPatenteRequestType request, ) method.

How should I use it ?

This is the script I use in a button to generate it:

import sys, logging  
from suds.client import Client  
from xml.dom.minidom import parseString

- Make a call to the service and create the type of parameter needed to send it.  
client = Client(‘[https://fwshomo.afip.gov.ar/wsctg/services/CTGService\_v3.0?wsdl](https://fwshomo.afip.gov.ar/wsctg/services/CTGService_v3.0?wsdl)’)  
req = client.factory.create(‘consultarCTGActivosPorPatenteRequestType’)

- It require a sub Type “authType” and an integer parameter “license plate”  
auth = client.factory.create(‘authType’)  
auth[‘token’] = token  
auth[‘sign’] = sign  
auth[‘cuitRepresentado’] = Int8Value

- I pass the sub type “auth” data and the license plate  
req[‘auth’] = auth  
req[‘patente’] = stringLicensePlate

- Call the service passing it the parameter type “consultarCTGActivosPorPatenteRequestType” created before  
result = client.service.consultarCTGActivosPorPatente(request=req)

And that’s it!  
Print the response in an area text or you can do whatever you need with it.

Hope it helps!
