Parse lets you store whatever key-value pairs you need using a simple JSON input. These Choreo allow you to create and mange your objects on Parse.
To use the Choreos in this bundle, you'll need to sign up for a Parse account, and register your app. After registering, Parse provides you with an Application ID, REST API Key, and a Master Key which are used by the Choreos to authenticate with Parse. Most Parse Choreos only require an Application ID and REST API Key, but a few will require the Master Key.
