Payments API for Ecommerce Platforms
Payments API for Ecommerce Platforms
A payments API for ecommerce platforms that need orders, catalog, checkout, refunds, and inventory-aware commerce state in one system.
Teams searching payments APIs for ecommerce platforms usually need more than card collection. They need catalog items, order state, hosted or embedded checkout, refunds, and inventory behavior that stay tied together.
Flint exposes items, orders, hosted checkout, payment links, refunds, and subscriptions through one public platform instead of splitting ecommerce state across processor primitives and app glue.
Catalog items can resolve into order line items with inventory-aware behavior, so pricing and stock logic stay closer to the same commerce model as payment collection.
Hosted checkout, embedded payments, and reusable links can all sit on the same order-backed system instead of forcing a platform to choose one surface too early.
Use This Platform Shape When
Your ecommerce product needs orders, catalog, checkout, refunds, and recurring billing to live on one platform model instead of across several side systems.
You want item and inventory behavior to stay close to the same API family as payment collection and post-purchase workflows.
Your team supports multiple buyer payment surfaces and needs them all to point back to the same order-backed truth.
Catalog-backed checkout
Resolve real item records into line items so pricing, tax behavior, and inventory-aware rules stay attached to the same sale record.
Hosted and embedded collection
Mix hosted checkout, payment links, and embedded payments without turning each collection surface into its own system of record.
Refunds after fulfillment
Keep post-purchase adjustments attached to the same order and payment workflow that support and finance already read.
Subscription-powered products
Add recurring products and later billing flows without splitting the customer and order model away from the rest of the platform.
Choose Something Narrower When
