Q: Call a SOAP web service with HTTPS without certificates I want to call a third party web service from TIBCO BW6.X via SOAP over HTTPS by using basic authentication.
I can do it with SOAPUI just by adding authorization as a HTTP header with the key (like Authorization: Basic QWxhZGRpbjpPcGVuU2VzYW1) and it works fine. But using BW, I have to create an SSL resource with certifcates to use HTTPS. 
My question is : Can I connect to a web service using HTTPS URL without SSL/certificates? If yes, then how? else, why can I do it with SOAPUI?
Thanks.

A: The answer depends on the soap client you are using. Basically you need just ignore the certificate validation as far as i interpret your question.
Example for php:
Disable certificate verification in PHP SoapClient
