Dedicated to the Hydrogen framework, headless commerce, and building custom storefronts using the Storefront API.
We are planning to develop a sales channel app.
I would like to set up a bank transfer as a payment method from customer to merchant, but according to this page (https://shopify.dev/apps/channels#build-a-sales-channel-app-with-cart-) , it only mentions that sales channel needs to be developed with Permalinks or Checkout API.Can we set up a bank transfer in using the Checkout API Or can we avoid using the Checkout API if we want to do a bank transfer?
