Glossary | Truemed

Key terms used throughout the Truemed docs. Each entry links to a fuller explanation where one exists.

Glossary term	Definition
Authorization	Placing a hold on a customer’s funds without moving them yet. With manual capture, you authorize at checkout and capture later.
Capture	Settling a payment by moving previously authorized funds. Capture can happen immediately or be delayed.
Eligible with LMN	A product that qualifies for HSA/FSA spending only when the customer completes a health survey and receives an LMN. See What “Eligible with LMN” Means.
FSA (Flexible Spending Account)	An employer-sponsored, tax-advantaged account customers can use for qualified medical expenses.
Health survey	A short questionnaire the customer completes during checkout so Truemed can assess HSA/FSA eligibility and, when needed, issue an LMN.
HSA (Health Savings Account)	A tax-advantaged account paired with a high-deductible health plan, used for qualified medical expenses.
Immediate capture	The default payment flow where Truemed captures funds automatically after the customer completes checkout and the payment clears review. Contrast with manual capture.
Letter of Medical Necessity (LMN)	Documentation from a licensed provider that qualifies a purchase for HSA/FSA spending. Truemed generates it as part of the checkout flow.
Manual capture	Also called delayed capture. A payment flow where you authorize funds at checkout and capture them later, usually when you fulfill or ship. See Manual/Delayed Capture.
Partially eligible	A product whose price is only partly an eligible medical expense. Truemed identifies a comparable general-use product and uses its price as the non-eligible baseline; the remaining amount above that baseline is the portion that qualifies for HSA/FSA spending.
Pay at checkout	The flow where a customer pays directly with their HSA/FSA card during your normal checkout. Contrast with reimbursement. See Core Concepts.
Payment session	The Truemed-hosted flow a customer is redirected to in order to verify eligibility and pay. The core object behind pay-at-checkout integrations. See How Truemed Checkout Works.
Payment token	A stored, reusable reference to a customer’s HSA/FSA payment method—used to bill subscriptions and other recurring charges.
Pre-approved	A product that’s HSA/FSA-eligible with no LMN required—no health survey, faster checkout. See What “Pre-approved” Means.
Product catalog	Truemed’s record of the SKUs you sell and their eligibility status, which powers collections, the PDP widget, and checkout messaging. See Product Catalog.
Qualification session	A pre-screen that determines a customer’s HSA/FSA eligibility ahead of, or independent of, a specific purchase.
Reconciliation	The reporting that ties Truemed payouts and transactions back to your orders. See Reconciliations.
Refund	Returning captured funds to the customer’s HSA/FSA account.
Reimbursement	The post-checkout flow: a customer pays normally, then submits a Truemed-issued LMN and itemized receipt to their HSA/FSA administrator to be paid back.
SKU	A unique identifier for a product you sell. You submit SKUs to Truemed so it can determine their eligibility.
Subscription	A recurring HSA/FSA charge billed on a schedule via a stored payment token. See Subscriptions.
Substantiation	Providing proof that a purchase was a qualified medical expense, sent directly to a benefits administrator or TPA. See Direct Substantiation.
Void	Canceling an authorization before it’s captured, releasing the hold on the customer’s funds.
Webhook	An HTTP callback Truemed sends to notify your system of events—such as a payment reaching `captured`. See Webhooks.
