Slack Error: "Apologies, but you are not authorized to install Vacation Tracker"

If you see this exact error during Slack signup or login, the cause sits in your Slack workspace — not in Vacation Tracker. The Workspace Owner has restricted which apps can be installed, and Vacation Tracker hasn't been pre-approved yet.

The Error

"Apologies, but you are not authorized to install Vacation Tracker"

It appears in the Slack OAuth window after you click Sign in with Slack at app.vacationtracker.io/signin.

Why It Happens

Your Slack Workspace Owner has restricted app installation to a pre-approved list, and Vacation Tracker isn't on that list yet. This is a Slack workspace setting — Vacation Tracker can't bypass it from our side; the fix happens inside Slack's admin console.

The Fix (for the Slack Workspace Owner)

  1. Go to slack.com/apps/manage/permissions as the Workspace Owner.
  2. Find the Approved Apps setting (or "App Approval").
  3. Approve Vacation Tracker for the workspace.
  4. Once approved, return to app.vacationtracker.io/signin and click Sign in with Slack again.
Slack workspace admin console at slack.com/apps/manage/permissions with the Approved Apps section open and Vacation Tracker listed

Slack has a guide covering app management for workspaces — useful if you want the full picture or your settings page looks different from a teammate's:
