We are looking to continue our integration with Meta/Facebook Commerce. Per Meta:
"Since June 5, 2023, any new shops you create use Checkout with Facebook and Instagram. If you have shops created before June 5, you have until April 24, 2024 to enable Checkout with Facebook or Instagram. Learn more.”
From what I can tell if we do this on our own it would require us to setup a whole other commerce setup to manage. They have direct integrations with Shopify, Magento, BigCommerce.
