Integrate ArtStoreFronts with Meta

I need a developer to help set up a storefront on Instagram and Facebook to sell my paintings. I use ArtStoreFronts.com, which does not currently support an API to connect Meta/Facebook/Instagram with my shopping cart checkout at jonleafstedt.com. When customers shop from my catalog on these platforms, they cannot complete checkout on my site. I need custom code to enable this flow, similar to how Shopify handles Meta integrations. The goal is to create a seamless shopping experience so customers can browse, select, and checkout directly from Instagram and Facebook.
