# Jira connection

After installing the Intercom app, it must be connected to Jira. This connection consists of two components:

* the **Jira site** that you would like to connect to your Intercom workspace, and
* the Jira user used by the Intercom app to read and write information to and from the Jira site - we refer to this as the **Intercom app user** or simply the **app user**.

This page describes these two elements of the Jira connection.

## Jira site

Each installation of the Intercom app is connected to a single Jira site. The Jira site is selected during the app installation process and can only be changed by [uninstalling](https://docs.toolsplus.io/intercom/jira-cloud-for-intercom/guides/intercom-administrator/uninstalling-the-app) and [re-installing the app](https://docs.toolsplus.io/intercom/guides/intercom-administrator/setting-up#installation).

## App user

Any operation in the Intercom app that involves interaction with Jira (e.g., create a work item or retrieve available Jira spaces) will be executed by the **app user**. The app user is the Jira user who was logged in to Jira [when the Intercom app was installed](https://docs.toolsplus.io/intercom/jira-cloud-for-intercom/guides/intercom-administrator/setting-up) and the connection to Jira was authorized.

While not strictly necessary, we do recommend setting up a dedicated Jira user for the Intercom app. You may call this user *Intercom app* or anything else you like. Benefits of setting up a dedicated user for the Intercom app include:

* Work items created via the Intercom app have a generic user (the app user) as the work item reporter.
* You can fine-tune and control access to Jira resources by configuring permissions of the app user (see [Restricting app access](https://docs.toolsplus.io/intercom/jira-cloud-for-intercom/guides/intercom-administrator/restricting-app-access) for more details).

You can find the currently configured app user in your app by following the guide on [inspecting app information](https://docs.toolsplus.io/intercom/jira-cloud-for-intercom/guides/intercom-administrator/inspecting-app-information). If you would like to change the Intercom app user, follow the steps on [Changing the Intercom app user](https://docs.toolsplus.io/intercom/jira-cloud-for-intercom/guides/intercom-administrator/changing-the-intercom-app-user).
