Send/Cancel Meeting Request and Generate iCalendar

Overview

Send and cancel a meeting request (iCal/vCal event) and generate the iCal String so that it can be written to a file.

This version is for Appian 22.3 and above. Cloud customers on a lower version of Appian that want to install this plugin should open a support case. Self-managed customers can find the latest jar for Appian 22.2 and lower version in the appmarket download file.

Key Features & Functionality

Contains three Smart Services that can

Generate an iCalendar String so that it can be written to a file
Send a Meeting Request (iCal/vCal event)
- Returns the meeting unique identifier (uid) so that it can be used later to cancel the meeting request if needed
Cancel a Meeting Request (iCal/vCal event)
- Given a uid returned by a previous execution of "Send Meeting Request", it allows you to cancel the meeting request and have it removed from the guests' calendar

A sample Appian application is included with the download of this Plug-in. Release notes are also provided as part of the download package.
