Steam Web API GetCollectionDetails not working

Question

I'm attempting to output a list of addons from a steam workshop collection. Every time I do so, it does not work. Here is the api link I am using.

Link: https://api.steampowered.com/ISteamRemoteStorage/GetCollectionDetails/v0001/?publishedfileids=532551393&format=json

Keep in mind, I'm using this application on the google chrome store called "Postman" to post the api, but always resulting in this error message.
