Execute a checkout for memberships, fees, or bookings. Provide either memberships/fees or a booking, but not both. This endpoint creates billable items and may trigger invoice generation, payment charging, email notifications, and legal document signing depending on the provided options and the organization's billing flow.
Memberships/Fees flow: Creates memberships and/or fees for the member. The checkout options control whether an invoice is generated immediately, whether the member is charged, and whether a credit card is required. If shouldRequestApproval is true, the order is created but payment is deferred and an approval request email is sent instead of the standard checkout confirmation.
Booking flow: Creates a booking for the specified resource and time slot. If the booking produces fees, an invoice is generated and processed automatically. This flow simulates the booking experience from the members portal or public calendar.
Required scopes: flex.billing.checkout.create
