Creates a payment with a unique reference (`pspReference`) and attempts to obtain an authorisation hold. For cards, this amount can be captured or cancelled later. Non-card payment methods typically don't support this and will automatically capture as part of the authorisation. > This endpoint is part of our classic API integration. If using a newer integration, use the `/payments` endpoint under Checkout API instead.
