About Flex Extensions
Flex Extensions (formerly Flex Marketing) works alongside the Flex Payments app to bring HSA/FSA to your Shopify store. It syncs your products to Flex and keeps HSA/FSA eligibility up to date across your catalog. Use the included template blocks to quickly add branding and an information modal that explains to your customers how they can unlock their HSA and FSA cards on your site. It's a no-code solution with customizable assets to fit the style and branding of your site.
