Quickstart

Step 1: Choose your auth method

Method	Best for
OAuth	Interactive clients (Claude.ai, Cursor, VS Code) — authorize via browser, no token setup
API Token	Scripts, automation, or clients without OAuth support — create once in Formester → API

→ Full authentication guide

Step 2: Connect your AI client
