The @fluid-app FairShare SDK continues to use its own published public-v2025-06 contract. > Authenticate with the header Authorization: Bearer ; public storefront read endpoints require no auth. > Lists use cursor pagination via the page[cursor] and page[limit] query params; follow meta.pagination.next_cursor until it is null. > Never use /api/company/v1 or /api/v1 paths, page/per_page params, or offset pagination — they are legacy. > The OpenAPI specs under api-reference/ are the authoritative contracts; prefer them over prose when in doubt. api-reference/storefront-v2026-04.yaml covers the v2026-04 storefront surface (/api/v202604/... paths); api-reference/auth-v0.yaml covers the unversioned auth surface (/api/... paths — authentication, MFA, social auth, and token exchange); api-reference/checkout-v2026-04.yaml covers the v2026-04 checkout surface (/api/checkout/v2026-04/... paths — carts, cart auth, discounts, items, subscriptions, orders, enrollments, and store config); api-reference/public-v2025-06.yaml covers the Public SDK surface used by the @fluid-app FairShare SDK, including its parallel cart lifecycle, browser integrations, versioned payment callbacks, unversioned public utilities, and the cart price-override operation; api-reference/payment-v2026-04.yaml covers the v2026-04 payment gateway admin surface (/api/payment/v2026-04/... paths, bearer-authenticated — gateway CRUD, gateway purchase/authorize/$0-verify, transaction list/show and capture/void/credit, and merchant payment configuration); api-reference/payments-v2026-04.yaml covers the v2026-04 cart payment surface (/api/payments/v2026-04/carts/{cart_token}/... paths, authenticated by the cart token in the path with no bearer — payment-method selection, VGS card tokenization, 3D Secure verification, and PayPal/Braintree/Klarna/Apple Pay flows); api-reference/commerce-v2026-04.yaml covers the v2026-04 commerce order-editing surface (/api/v202604/orders/{order_id}/edits paths, bearer-authenticated — post-checkout order edits that atomically insert items and add adjustments/discounts, with an optional dry-run preview); api-reference/webhooks-v0.yaml covers the unversioned webhooks surface (/api/... paths — webhook registration, delivery payloads, callback registrations, company events, and webhook/callback schemas). > Successful responses wrap the resource payload alongside a top-level integer status and a meta object. # Fluid: The We-Commerce Platform for Direct Sales Teams > Fluid is a We-Commerce platform combining e-commerce and direct sales tools. Learn how Fluid helps merchants and reps sell together with full transparency. Fluid is a We-Commerce platform built for merchants and direct sales teams who want to sell together — not in silos. It unifies your storefront, sales rep attribution, global payments, and customer identity into a single connected system, so every party in a sale gets full credit and visibility. Whether you're launching a new product, onboarding a network of reps, or expanding into new markets, Fluid gives you the infrastructure to grow without stitching together dozens of third-party tools. Set up your account, install FairShare, and make your first API call in under 10 minutes. Explore every component of the Fluid platform and understand how they work together. Integrate FairShare attribution and Fluid's client-side tools into your existing website. Browse the full Fluid REST API — products, orders, customers, commissions, and more. ## Key Platform Components Fluid is composed of several purpose-built modules that work independently or together. Here's a quick orientation to the most commonly used components. ### FairShare Attribution FairShare is Fluid's JavaScript attribution SDK. It tracks which sales rep deserves credit for a purchase by following cookies, fingerprints, and referral routes — even across domains you don't own. Install one script tag on any site and FairShare silently attributes every conversion back to the right rep. ### Fluid Payments Fluid Payments is a global payment aggregator that supports 300+ alternative payment methods (APMs) across 100+ countries. Accept Apple Pay, Google Pay, GCash, AliPay, local bank transfers, and dozens of regional wallets without managing separate payment processor accounts. All card data is stored in Fluid's PCI-compliant vault. ### We-Commerce Checkout Fluid's one-page checkout lives at [checkout.fluid.app](https://checkout.fluid.app) and is shared across every Fluid-powered storefront. Returning customers check out instantly using saved profiles, reducing cart abandonment without any extra development work on your end. ### Website Editor The Website Editor is a drag-and-drop site builder that uses Liquid templating. Start from one of three themes — Base, Vox, or Fluid — and customize your storefront without writing a line of code. Developers can drop into the template layer at any time for full control. ### Droplet Marketplace Droplets are pre-built third-party app integrations you can add to your store with a single click. Because every Droplet is built against Fluid's native APIs, they work seamlessly with your checkout, rep attribution, and commission engine — no middleware to configure or maintain. ## Need Help?
