Key Features
Hosted atcheckout.fluid.app — Fluid runs and scales the checkout infrastructure for you. There are no servers to provision, no PCI compliance scope to manage on your side, and no checkout code to keep up to date. You embed or link to the checkout, and Fluid handles the rest.
One-page checkout with saved profiles — The entire purchase flow — contact details, shipping address, payment method — lives on a single page. Returning customers with a Fluid Pay profile can pre-fill all their details automatically, eliminating the friction that causes cart abandonment. First-time buyers are prompted to save their details for future purchases at the end of the flow.
Built-in operational features — Address validation, real-time shipping rate calculation, tax computation, inventory checks, and discount code redemption are all handled by Fluid Checkout out of the box. You configure your shipping carriers, tax rules, and inventory in your Fluid dashboard; the checkout enforces them automatically on every order.
Full FairShare attribution — Checkout reads attribution data written by the FairShare SDK and records it against every order. Commission rules are evaluated at the moment the order is placed, so there is no post-purchase reconciliation step and no attribution disputes.
300+ alternative payment methods in 100+ countries — Fluid Payments powers the checkout’s payment layer. Buyers can pay with the local methods they prefer — bank transfers, digital wallets, buy-now-pay-later — without any additional integration work on your part.
How to Customise Your Checkout
Fluid Checkout is designed to be extended without forking or modifying the underlying checkout code. Use the following mechanisms to tailor the experience to your brand and business logic.Droplets
Droplets are third-party integrations that can embed their own UI inside the checkout at specific Drop Zone locations. Install a Droplet from the Droplet Marketplace to add loyalty point displays, upsell widgets, gift message fields, or any other functionality a Droplet provides.Drop Zones
Drop Zones let you embed external UI in configured checkout and order-confirmation locations. See Embed apps with drop zones for the available integration surfaces. For a direct REST integration, use List drop zones.Webhooks
Fluid Checkout emits events you can subscribe to so your systems stay in sync with buyer activity:cart_updated— Fired whenever a buyer modifies their cart: adding or removing items, applying a discount code, or changing a quantity. Use this to update inventory holds or trigger personalisation logic.cart_abandoned— Fired when a buyer leaves the checkout without completing their purchase. Use this to trigger recovery emails, retargeting campaigns, or rep follow-up tasks.
Middleware
For advanced use cases — custom discount engines, dynamic product bundling, or complex B2B pricing rules — Fluid supports middleware hooks that intercept cart operations before the checkout applies its standard logic. Contact your Fluid account team to discuss middleware configuration for your account.Fluid Pay has over 2 million payment-ready customers with saved profiles from previous purchases across the Fluid network. When one of these customers reaches your checkout, their address and payment method are pre-filled automatically, letting them complete their order in a single click — no separate fast-checkout integration required.
