Truemed provides merchants with ways to let eligible customers use HSA/FSA funds for qualifying purchases. Its payment integration adds a Truemed payment option to supported checkouts; merchants can also offer a post-purchase qualification flow for customers seeking reimbursement. Truemed reviews product catalogs for eligibility and handles the customer health-intake and documentation process. Merchant setup includes product review and technical configuration. Shopify merchants can use the Truemed Payments App, while Truemed’s documentation also describes integrations for other storefronts and custom API-based checkout.
