Headless Ecommerce Payments API

Headless Ecommerce Payments API

A headless ecommerce payments API for teams that want frontend freedom without rebuilding orders, checkout state, and post-purchase operations from scratch.

Teams searching headless ecommerce payment APIs usually want full frontend control, but they still need a backend commerce model that can own orders, totals, refunds, and checkout surfaces coherently.

Flint lets teams keep the frontend headless while still using one order-backed backend for hosted checkout, embedded payments, links, refunds, and later billing flows.

The same item and order model can power storefront rendering, embedded checkout, and post-purchase workflows instead of making each surface invent its own payment context.

Headless does not have to mean payment-state chaos if the backend API already owns the sale, totals, and lifecycle history.

Use This Platform Shape When

Platform 1

Your storefront, app shell, or CMS layer needs full frontend control, but the backend still needs one durable order and payment model.

Platform 2

You want embedded checkout on your own UI without making refunds, links, and later collection feel disconnected from the original sale.

Platform 3

The team needs a backend commerce model that survives beyond the storefront render layer and keeps post-purchase operations coherent.

Scenario 1

Custom storefront checkout

Keep the buyer on your own domain and UI while Flint owns the order, payment intent, and later refund lifecycle underneath.

Scenario 2

Catalog plus embedded pay

Use item records and order line items as the backend source of truth while the frontend stays fully custom and channel-specific.

Scenario 3

Mixed hosted fallback

Start with embedded checkout, then hand off specific recovery or operator flows into Flint-hosted surfaces without changing the underlying sale model.

Scenario 4

Post-purchase operations

Keep refunds and support tooling attached to the same order instead of reconstructing purchase meaning from frontend state and processor objects later.

Choose Something Narrower When

Use the broader ecommerce-platform page when the main decision is the entire product surface rather than headless architecture specifically.
Use embedded-payments pages when the problem is implementation of embedded checkout, not the whole headless ecommerce stack.
Use hosted checkout pages when Flint should own more of the buyer payment surface rather than your frontend.

Next Step

Wire the platform boundary first

Define auth, merchant scope, and install flow first, then let the narrower payment and checkout pages sit underneath it.
