StoreFront Checkout

[dotkonnek]

Hi,

i am using shopify storefront graphql API  and when i go to checkout is there any way i can complete checkout
without payment and once i received payment mark that order as paid.
or
right now i am using checkoutCompleteWithTokenizedPaymentV3 to get paymentData i need to send user card details to payment gateway but we don't want to take user card details at our end.
note: don't want to use admin side API
thanks
