Exalate is the most complete & flexible synchronization tool on the planet for issue trackers and service desks. You can start with basic synchronization scenario's straight out of the box. Or customize your sync for the most complex use cases using our intuitive scripting engine. The synchronization recreates all the necessary information that's been filled out on your ticket. This includes comments, title, description, and anything else your customers input on their ticket. Supports both uni- and bi-directional sync and offers full control of what is being shared and with who data is being synchronized. Supports synchronization for Zendesk, Jira, HP QC/ALM, ServiceNow, Github and other trackers.

To set this user you will need first to generate an access token for it and then input it during the installation. After installing you will be granted to access to the Exalate UI where you will need to configure a connection with the instance you would like to connect with.
