Request API with filter option

Hello Claudus, 

I'm extremely unfamiliar with the API functions. We only use it to schedule and check policies with Control-m. I tinkered around with our catalog images and my filter returned only the images for my specified client. Based on the json version, I'm guessing you aren't on 9.1? I've tested it on 8.3.0.1 and 9.1 and they returned only the client I filtered it with. I just used the api-docs portal with the Try Out function

clientName eq 'client name registered in NBU' 

I could show you the results but its literally just a screenshot of "clientName":                       ", to protect my place of employments information.
