You must have Admin access to the Slack Workspace in order to install DataFetch. If you do not have permission, you may submit a request to the workspace admins to install the app.
Slack Workspaces which are on the Free Plan are allowed a maximum of 10 apps. If your workspace has reached its maximum number of apps, one will need to be removed in order to install the DataFetch app.
Installing The App
Via The Web
From your app, click Apps from the top left corner of your app. If you can’t find this option, click Browse Slack, then clickApps.
Type DataFetch in the search box and click Add. You will be taken to the Slack App directory on your browser.
