**Can I connect more than one Shopify store?** Not in this version: each tenant has a single Shopify connection at a time (the "principal" one, Connections tab). **The domain isn't valid — what message will I see?** If the domain doesn't have the right format or the store doesn't respond, both when connecting and when testing the connection you'll see *"The token isn't valid; check it and try again"* (code `INTEGRATION_CREDENTIAL_INVALID`). Check the domain in your Shopify panel and repeat section 4. **Shopify isn't responding — what message will I see?** If Shopify has a temporary incident, you'll see *"The provider isn't available right now. Try again later"* (code `INTEGRATION_PROVIDER_UNAVAILABLE`) — it's not a problem with your store, try again in a few minutes. **Can the agent complete the checkout on its own?** No. The agent prepares the cart and shares your store's payment link — the actual charge always happens on Shopify's page, with your own payment methods configured there. **Why don't I see the Shopify card?** Shopify only appears by default for businesses with a store (e-commerce); if your vertical doesn't show it, contact your provider's support (Manual 28).
