ISY schlange lock to iOS app

[Matherz]

First off I'd like to start off saying, I'm not entirely sure where to post this question. Sorry if its in the wrong place. If it is would someone send me a link to the correct forum.

I am trying to unlock my schlange lock using a button that on my ios app. I'm using the following string rest string: http://192.168.1.73/rest/nodes/ZW004_1/cmd/DON

 

this works for my lights but not my lock for some reason. Im still getting a status code of 200 when I click it. I was wondering if I had the wrong string?

 

Thank you!
