# Connect tools & automate tasks

Connect, simplify, and automate. Discover the power of apps and tools.

# Add apps to your Slack workspace

**Who can use this feature?**

- All **members**(by default)
- Available on [**all plans**](https://slack.com/pricing)

Add apps to your workspace to connect the tools and services you use every day and get more work done right from Slack.

### **What to expect**

- By default, any member of a Slack workspace can install an app. Once an app is installed, all members of the workspace can connect their accounts to use it.
- Workspace Owners can [turn on app approval](https://slack.com/help/articles/222386767-Manage-app-approval-for-your-workspace) to require admin approval for all apps. Members can install any apps approved by a Workspace Owner, and may be able to request approval for other apps. If an app has been restricted, members cannot install or request approval for it.
- Apps that are published in the Slack Marketplace have been [reviewed by our team](https://api.slack.com/start/distributing/guidelines) for user experience and security. Any app not listed in the Slack Marketplace will display a banner letting you know it hasn’t been reviewed by Slack before you install it.

**Tip:** Visit our [Guide to apps in Slack](https://slack.com/help/articles/360001537467-Guide-to-apps-in-Slack) to learn more about apps.

## **Install an app**

1. From your desktop, click **Tools** in the sidebar. If you don't see this option, click **More** to find it.
2. Click **Apps**.
3. Search for an app, then click **Add**. You’ll be taken to the Slack Marketplace.
4. Click **Add to Slack**.
5. Follow the prompts to install the app. If the app is already installed, you'll be prompted to connect your account instead.

**Note:** If you don't see the **Tools** tab in your sidebar, look for the **Automations** tab instead.

## **Request app approval**

By default, members can request to install apps when app approval is turned on.

1. From your desktop, click **Tools** in the sidebar. If you don't see this option, click **More** to find it.
2. Click **Apps**.
3. Search for the app you’d like to request, then click **Add**. You’ll be taken to the Slack Marketplace.
4. Click **Add to Slack**.
5. Add a custom message with more context about your request. This step may be optional, or required by your Workspace Owners.
6. Click **Submit** to send your request. Once it’s been reviewed, you’ll get a direct message (DM) from Slackbot.

**Tip:** If you don't see the option to request apps, [ask a Workspace Owner for help](https://slack.com/help/articles/360003534892-Browse-people-and-user-groups-in-Slack).

## **Update an app**

Apps use sets of [permission scopes](https://api.slack.com/scopes) to determine what information they can access in Slack and how they can use that information. When a developer changes how their app works, they often add or remove scopes. To access an app’s new functionality, you may need to grant permission for the new scopes by re-authorizing the app's connection to Slack. How this works depends on whether or not app approval is turned on for your workspace.

DefaultApp approval required

Any member of a workspace can review and accept an app’s new scopes using an installation link provided by the app developer:

- In most cases, members can access installation links by clicking the **Add to Slack** button on an app’s page in the Slack Marketplace.
- In other cases, an app’s developer may include an installation link in their app’s **Home** tab, or send a message letting their users know to update their app along with a link to do so.

Any member of a workspace can submit an app request using an installation link provided by the app developer:

Once a Workspace Owner or app manager reviews and approves the app’s new scopes, any member can complete the app update using the installation link.

## Reinstall an app

For added security, it’s a good idea to periodically rotate app tokens for custom or third-party apps. If you notice an app token has been revoked, or you'd like to rotate it, you can reinstall the app.

1. Head to the [Slack Marketplace](https://my.slack.com/marketplace).
2. Click **Manage** in the top right.
3. From the **Installed Apps** page, search for and select an app.
4. For a custom app, click **Remove App** at the bottom of the page. For a third-party app, click the **Configuration** tab from the app page, then click **Remove App**.
5. Complete the steps to reinstall the app.

**Note:** If [app approval is enabled](https://slack.com/help/articles/222386767-Manage-app-approval-for-your-workspace#manage-app-approval), only Workspace Owners and members with permission to manage apps can reinstall a third-party app.
