Hi I am able to find option to add oAuth profile for providing token to SOAP authentication. I tried both open source and Pro versions. In your documentation, it is asking to add oAuth profile as mentioned here but there is no such option.
Im running readyapi! so cant comment on the open source version, however if the OAuth functionality isnt available in open source soapui, it is possible to create all the individual REST requests that would be handled by the OAuth functionality as i did this about a year ago when the OAuth authentication i was testing wasnt handled by the OAuth functionality in readyapi! due to weird OAuth v2.0 customisations on the project i was working on.
if this helped answer the post, could you please mark it as 'solved'? Also if you consider whether the title of your post is relevant? Perhaps if the post is solved, it might make sense to update the Subject header field of the post to something more descriptive? This will help people when searching for problems. Ta
