This connector has 2 blocks and 1 screen (for callback) and several actions.

Just add the OneDriveAuth Block through manage dependencies in your application and then drag and drop this block anywhere in application. This block triggers one event which needs to be handled by the screen which is using this block. And this event will give the binary of the file selected by user from his/her OneDrive account along with few other parameters. Also this block expects one input parameter, call the GetBookmarkableURL() and pass this in argument.

Note : Make sure you have set the default values of (Application (client) ID & Secret ID) Site Properties from the values you got from portal of Microsoft. (For Details check Documentation)
