I have exposed the Appian process model as a webservice. This webservice ha

Not sure if I understand your question correctly but once you publish it as a web service, clicking on that web service (System tab) will show you the WSDL URL that you'll have to use to call it. That's all you need.

Do you mean like we don't have to do any custom settings in custom.properties file

To consume it? No

Thank you Eduardo !! So my understanding is when we publish the process model as webservice..it can be directly used by another integration platform. We do-not need to set any properties in appian layer

Is my understanding correct

Correct

Thank you :)

When SOA calls the Appian wsdl ,it asks for authentication. Where do we setup the authentication.

You need to pass the credentials of an existing user in Appian (e.g. a service account you create). The password is the Appian password not LDAP's

Thank you so much Eduardo :)
