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 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 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 to learn more about apps.

Install an app

Note: If an app is already installed, you'll be prompted to connect your account instead.

Request app approval

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

Tip: If you don't see the option to request apps, ask a Workspace Owner for help.

Update an app

Apps use sets of permission 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.

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 If you notice an app token has been revoked, or you'd like to rotate it, you can reinstall the app.

Note: If app approval is enabled, only Workspace Owners and members with permission to manage apps can reinstall a third-party app.
