SUMMARY:   If you are seeing the following error message during our Slack integration signup or login, it is because the Slack workspace owner has limited permissions for installation and usage of Slack apps for your workspace.

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

# 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 (https://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)

- Go to slack.com/apps/manage/permissions (https://slack.com/apps/manage/permissions) as the Workspace Owner.

- Find the Approved Apps setting (or "App Approval").

- Approve Vacation Tracker for the workspace.

- Once approved, return to app.vacationtracker.io/signin (https://app.vacationtracker.io/signin) and click Sign in with Slack again.

## Reference: Slack's Own Documentation

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:

Different but related error

If the error is more generic (workspace permissions in general, no mention of "not authorized"), see Slack Troubleshooting: Slack Workspace Permissions (https://vacationtracker.io/knowledge-base/slack-troubleshooting-slack-workspace-permissions/).
