Official Square API documentation ↗Account access & setup
An authorized seller access token; OAuth is the documented route for a third-party application. Request the endpoint's appointment or order scopes and map the correct location, bookable service and team member. Buyer-level appointment operations are available to all sellers, with control limited to application-created bookings. Seller-level writes need Appointments Plus or Premium and APPOINTMENTS_ALL_WRITE as well as APPOINTMENTS_WRITE. Check support_seller_level_writes first. Orders retrieval requires ORDERS_READ; payment processing and non-Square-payment order fees are separate.
