Flex Shopify Payment App - Flex Documentation

Shopify Checkout Page

Flex provides a Shopify payment app to make it easy to accept HSA/FSA payments in your Shopify store checkout flow.

When a customer goes to checkout from your Shopify store, they’ll be able to select “Flex | Pay with HSA/FSA” and then be redirected to a hosted Flex Checkout page.

Hosted Flex Checkout Page

Upon successful completion, the customer will be redirected back to the Shopify success order page. The order will appear in your Shopify admin just like a regular order.
