## What it is
An OAuth2 library for Google Apps Script that creates, authorizes, and refreshes OAuth2 tokens using Apps Script's StateTokenBuilder and /usercallback endpoint. It lets Apps Script projects authenticate against any OAuth2 provider, including Google and third-party APIs.

## Use cases
- authenticate a Google Apps Script against a third-party OAuth2 API
- refresh expired OAuth2 access tokens in Apps Script
- connect Apps Script to services not covered by built-in or advanced services
- handle OAuth2 redirect callbacks in a Google Workspace add-on
- store and reuse OAuth2 tokens across script executions

## When to choose
- your Apps Script needs OAuth2 access to an API without built-in Apps Script support
- you need token refresh handling in a Google Workspace automation
- you want a maintained, Google-published library for OAuth flows in Apps Script

## When to avoid
- you only call Google APIs covered by built-in or advanced Apps Script services
- you can simply declare scopes in the manifest and use ScriptApp.getOAuthToken()
- you are not working within Google Apps Script
