Connect Grok Bot (xAI) to QuickBooks

Get the line for Grok Bot (xAI)Connect QuickBooks first

Three steps

  1. Create a free 0n3 account and connect QuickBooks. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into Grok Bot (xAI). xAI's always-on Grok Bot. Add 0n3 as a custom connector once, and your Bot can use every app you added, around the clock.
  3. Ask Grok Bot (xAI): whoami. Then: "Create an invoice in QuickBooks".
Add 0n3 to Grok Bot (desktop app)
  1. Open Grok Bot on your computer. In the sidebar, click Connect apps.
  2. At the bottom, click Add a custom connector.
  3. For Name, type 0n3. For Type, pick Remote HTTPS. For Server URL, type https://0n3.app/mcp.
  4. Under HTTP headers, add Authorization with the value Bearer <your 0n token>
  5. Click Add plugin.
Then try it: send your Bot this
  1. "Use 0n3: who am I, and which apps can you reach?"
  2. "Every weekday at 8, use 0n3 to list today's CRM appointments and new Stripe payments, and post a summary to me."

The line above carries a placeholder; 0n3.app/install mints a real key named for Grok Bot (xAI) and fills it in.
