In order to configure TFS4JIRA in your JIRA Cloud instance, go to Administration->Add-ons->TFS4JIRA Settings. This will open a page shown in a screenshot below
In order to work properly, your TFS4JIRA Cloud add-on requires that you install the synchronizer application in your local network (see Installing TFS4JIRA Synchronizer for a description and requirements for the synchronizer).
Issues and Work Items Synchronization Setup
The TFS4JIRA Cloud does not require any special configuration for allowing the issues synchronization to work, beyond what is described in Configuring TFS-JIRA issues synchronization. The Synchronizers seen section of the settings page lists all the web requests made by your synchronizer application to your JIRA Cloud instance since the last JIRA restart.
Remember that Encryption Password should be set at the first time you are configuring Checkins Synchronization and it should match password that is set in Synchronizer application.
Check-ins Synchronization Setup
For check-ins synchronization, the synchronizer web application will need to enable incoming connections from the internet - specifically from the IP address of the tfs4jira-ondemand.spartez.com host. If necessary, you will need to set up some firewall rules that allow such connections. It is ok to expose the synchronizer's web interface using SSL. Additionally, the communication between this host and the synchronizer is encrypted with symmetric AES cipher so that your data remains secure
In order for the check-ins synchronization to work, JIRA must know the externally visible address of your synchronizer web application. This most likely means that you have to configure your web server to proxy web connections from the internet to the synchronizer. Details of such proxy setup depend on what kind of web server you have - please refer to your web server documentation for more information.
In order to set up check-ins synchronization, you have to provide the external address of your synchronizer application and set up an encryption password, which has to match the password configured in your sycnhronizer (see Configuring TFS check-ins synchronization).
Clicking the Update button applies the new settings. Clicking Test makes the TFS4JIRA add-on attempt to contact the synchronizer. When the connection is successful, the status of the synchronizer (containing the number of configured TFS source code repositories and some other info) is displayed. In case of communication problem, an appropriate error message is displayed
