python-zeep | A Python SOAP client | SOAP library

I am very new to wsdl, asmx, client, zeep and other topics related to SOAP APIs, and I have to fix a system of "REST, SOAP APIs - service", made in Python by others.

Currently I am working only on my local machine. This is the main context:

In my project main folder myservice there are:

• a service made with Tornado, myservice > myserviceSrv.py, and

• a set of APIs whose logic is split into two scripts:

  • myservice > handlers > myservice_api.py: containing classes inerithing from tornado.web.RequestHandler, which contain posts methods calling the SOAP APIs in the externalcompany_myservice_api.py script.

  • myservice > handlers > externalcompany_myservice_api.py: containing a single class which contains the SOAP APIs methods that will call the externalcompany service SOAP APIs.

    One of these methods is ping, and my aim is to make it work, that is, I want it to get the correct response when I launch a post with Postman. In particular, the POST request from Postman should trigger the ping method of my service that should trigger the ping SOAP API that should trigger the corresponding SOAP API of the externalcompany service, which should answer back and in the end give me the post response.

• A module containing some configurations myservice > config.py, mainly the ones bound to tornado.options, the wsdl files path, and the APIs urls.

This is the problem:

I start my server(/service) and then I lauch the POST with Postman to http://localhost:30205/service/ping (with no inputs), but this is the log and traceback that I get:

I have problems to get SOAP request through Zeep, I get a (client) validation error... I have also tested with SoapUI and that does NOT give me the same validation error...

The specification below is from the server... Based on that specification, the OrderStatus and SynchStatus are needed to perform the request.

I'm trying to turn a previously working synchronous usage of the Zeep library into the Async version of this. On a request to the WSDL, the transport will always return a 404.

The following is the sync implementation and is working as intended.

When I view the raw request in SOAPUI i get = wsse:Security soapenv:mustUnderstand="1" in the section. When doing it with zeep and python i do not see this in the request sent to the server - and i'm getting securuty issues in the application logs

I am trying to make a SOAP request using Python zeep, which requires a sha256 signature with RSA 2048. For some reason I am unable to load the signature, and I get 'signature fails: cannot load cert' error upon trying to send the request.

sample code bellow:

I'm trying to call a SOAP endpoint using the Zeep library.

The endpoint has the following signature:

i have access to wsdl file and i need to get in response a list of drug

but i get stuck with it and here my try

I am able to send a simple SOAP request with Zeep.

I'm calling a SOAP WebService using Zeep, and it returns a JSON-like response with a datetime object. I want to write a micro-service using Flask and return proper JSON response. However, Flask complains that:
