How to set a certificate for a API request

I have a test case where I need to send a message to an SOAP API that requires a client side ssl certificate. Is there any way to do it in Katalon or in the groovy script itself.



Katalon Studio has not supported the feature yet. I will move this post to New Feature/Suggestion box.

Certificate for an API request would be great.

Yes, for us it would be awesome!!!

Any news on this request? I can’t continue with my test cases until I can resolve the 403 error as I cannot pass a certificate and password to the web service. Looks like I might have to use another software.

I got this problem and can not test my webservice
