Ecommerce Checkout API
Ecommerce Checkout API for Developers
An ecommerce checkout API for developers choosing between embedded checkout, hosted checkout sessions, and reusable payment links.
Teams searching ecommerce checkout APIs usually need to decide which buyer payment surface fits the storefront: embedded checkout on their own frontend, one-off hosted checkout, or reusable payment links for remote collection.
Flint gives embedded payments, hosted checkout sessions, and payment links on one platform, so the checkout decision can stay about workflow fit instead of vendor fragmentation.
Each buyer-facing surface can still tie back to the same order-backed model, which keeps checkout architecture from splintering the rest of the commerce state.
The same platform can support direct in-app checkout plus later recovery flows like hosted collection or invoice-based follow-up.
Use This Platform Shape When
The current decision is which buyer payment surface the ecommerce flow needs: embedded, hosted, or reusable remote collection.
You want every checkout surface to still point back to the same order-backed model so the rest of the system does not fragment.
Your team needs later recovery or operator-driven collection paths that can sit beside normal storefront checkout cleanly.
Embedded primary checkout
Keep the buyer in your storefront flow while Flint still owns the backend order and payment lifecycle.
Hosted order-specific checkout
Launch a Flint-hosted page when the order is known and the goal is one clean payment instance instead of a reusable public link.
Remote recovery and follow-up
Use reusable hosted links or invoice-led collection when the buyer leaves the main checkout but the balance still needs to be collected later.
Subscription or mixed basket flows
Keep one platform around checkout, signup, and later billing instead of splitting recurring and one-time collection into different systems.
