Custom website + Square Payments + Square POS/Orders API in Australia

Hi Square Community,

I’m working on a restaurant project in Australia and need clarification about a custom website integration with Square.

The restaurant has a completely custom-built website. It is NOT built using Square Online / Square Website.

Our intended flow is:

Customer orders from the custom website

→ Custom checkout

→ Square Web Payments SDK / Payments API

→ Payment is processed through Square

→ Order is created using the Square Orders API

→ The order should appear in the restaurant’s Square POS / Order Manager / KDS for staff to fulfil.

We have found Square developer documentation that appears to support custom payment and order integrations, but Square Support Australia has told us that API-created orders may not automatically appear in Square POS and that Square Online or another supported integration may be required.

Can someone from Square or anyone with actual experience confirm:

1. Can an Australian Square seller use a completely custom website (without Square Online) to accept Square payments?

2. Can that custom website create a paid pickup/takeaway order using the Square Orders API?

3. Can that API-created order automatically appear in Square POS / Order Manager / KDS for staff to fulfil?

4. If this exact workflow is NOT supported in Australia, what is the officially supported architecture for:

Custom website → Square payment → Square order → Square POS?

5. If it is supported, could you please share the exact documentation and detailed setup process/API requirements?

We are specifically looking for the supported solution for Australian Square sellers, rather than a Square Online solution.

Thanks.
