Why teams pick Swft

Section titled “Why teams pick Swft”

164 ms TTFB

Checkout loads in under 200 ms globally via Cloudflare’s edge network. Sessions pre-create on cart update — zero API round-trip on redirect.

WordPress optional

Drop the plugin in WooCommerce and Swft handles every checkout. Or skip WordPress entirely — Next.js, Medusa, and vanilla JS adapters ship in the box.

Modules, not monolith

Dunning, KYC, gift cards, fraud rules, bundles, donations, subscriptions. Each module is opt-in and configurable from the dashboard.

Partner-first API

Onboard your own merchants. Stripe Connect, custom domains, pre-confirmation hooks, Standard Webhooks. One bearer token, one OpenAPI spec.

Section titled “Popular guides”
Installation Get the plugin running on WooCommerce in under 10 minutes.
First Checkout Connect Stripe, place a test order, ship the live one.
Connecting Stripe Standard Connect, application fees, on_behalf_of, the lot.
Templates Five drop-in templates, all editable in the dashboard.
Custom Domains Serve your checkout from `checkout.yourstore.com`.
Webhooks Standard Webhooks signing, delivery log, manual replay.

For partners

Section titled “For partners”

The v2 Partner API lets a SaaS platform onboard its own customers as Swft merchants, drive checkout sessions on their behalf, and receive lifecycle webhooks.

Authentication Opaque bearer tokens, scopes, sandbox vs livemode, idempotency.
Merchant Onboarding Bundled merchant create + Stripe Connect in one call.
Booking Extensions Opaque metadata preserved end-to-end through every event.
Pre-confirmation Hook Capacity checks fire before Stripe is charged — no refunds.
Webhooks Standard Webhooks signing, retry, replay, inspect.
