Hi @Neeraj Kumar

Are you using the Web Service functionality from Blue Prism for this, right?

This is a problem with the Security Protocols.

If you try to call the api using a code stage, adding this line you will solve the problem:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Hello @PabloSarabia - Thanks for your reply.

WSDL is http based. so security protocol will come in picture?

I am not calling API via code stage.

@Neeraj Kumar,

If you're connecting to a SOAP web service over HTTP, as opposed to HTTPs, the TLS version shouldn't come into play. Does the web service you're connecting to have any sort of authentication (ex. HTTP Basic) enabled on it?

Cheers,

Hi @Neeraj Kumar

In addition to what Eirc has said, did you try to call your service with the SoapUI or Postman, just to test if the service repsonse correctly.

Bye :)

hello,

We are using basic authentication and successfully able to consume the Web service.
using action in object- receiving the error.

@PabloSarabia- did not use the Postman or SOAPUI so far.

Hi,

I suggest SOAPUi just to test the communication between your BP universe and the WS.

It's a simple software to perform web service calls. I use it whenever I have a communications problem to check whether the problem is in the service, in the program calling the service or in the communication between the machines.

Here is the link: https://www.soapui.org/

Hope this helps you.

Bye 🙂
