Before you start
- Add a payment method (with ZIP code) in Settings → Billing. Treecat needs one before it can talk to your marketplaces. You are still only charged when a crosslisted item sells.
- Install the Treecat agent and make sure it is online. See install the Treecat agent.

If the login gets stuck
- If nothing appears, click Open app again in the Connect dialog.
- If the app is not responding, quit it completely from the menu-bar or tray icon, reopen it, and try again.
- If the marketplace shows a block or captcha, wait a few minutes and try again.
- Check Settings → Events to see where the login stopped.
More than one account per marketplace
You can connect several accounts on the same marketplace. Each one appears as its own row where you can set the default account, change its settings, pause syncing, or delete it. Move lets you move a listing from one account to another.

Frequently asked questions
Does Treecat store my marketplace passwords?

Why does Treecat ask me to reconnect?
Marketplace logins expire every few months. Treecat shows a Reconnect banner and emails you. Reconnect from Settings → Marketplaces.
