Where do I find SALES_URL and DEVICES_URL?

Dashboard → Settings → POS after Custom POS is connected. They are also returned by GET on the sales URL.

Can I register a Receet tile through this API?

No. POS terminals and kiosks use the devices API. Receet tiles are added by serial in Hardware so inventory stays tied to hardware you purchased.

No. A sale with register_id creates that station if needed. Creating devices first is better so staff can map tiles before the first live sale.

Receet updates the existing sale. Use that for refunds, voids, and amount corrections.

paid, succeeded, and completed. pending, failed, and refunded do not publish a tap-to-receive receipt.

HTTP API for any checkout system. Push sales, manage registers, and Receet builds the receipt for the mapped tile.
