The hard parts of booking, already solved.
The pieces that take months to build right — done, and beautiful out of the box.
Timezone-true slots
Every opening is a UTC instant rendered in the customer's zone, with a switcher and DST-safe copy. No more “wait, is that my time or yours?”
Never double-books
The database guarantees one booking per slot. Concurrent requests get a clean “just taken — here's the next opening,” never a collision.
Any location type
In-home with address capture, secure video, or in-studio — each service knows what it needs and asks for exactly that, nothing more.
Three surfaces, one API
Hosted page, embeddable widget, and admin dashboard share the same contract — ship a booking flow in an afternoon, not a quarter.
Calendar sync & ICS
Two-way Google sync and an Apple-ready ICS feed keep every practitioner's calendar honest, automatically.
Reschedule by link
Customers manage their own appointments through a secure magic link — no account, no phone tag, no front-desk burden.
Three surfaces that share a soul.
One design system, one data contract — branded to feel like yours, everywhere your customers meet you.
The money screen
Three taps to a confirmed slot, fully branded.

A dashboard your front desk loves

Open the dashboardLive in an afternoon.
Define your services
Set durations, prices, location types, and your team. Cadence generates availability from your weekly hours, buffers, and notice rules.
Embed or share
Paste one script tag for the widget, or send the hosted link. Both inherit your brand and call the API through your server.
Run your day
Bookings land in the dashboard and on your calendar. Webhooks fire on every change so the rest of your stack stays in sync.
Your keys stay on your server. Always.
Server-side secret
The org API key lives in your backend env. Browsers only ever talk to your own route handlers.
Minimal customer data
Name, contact, service, time, location. No clinical notes, ever — HIPAA-minimal by design.
Idempotent & webhook-driven
Idempotency keys make retries safe; signed webhooks keep your systems consistent.
// Server route — the key never reaches the browser export async function POST(req) { const body = await req.json(); const res = await fetch("https://cadence.abhix-ai.com/api/v1/bookings", { method: "POST", headers: { Authorization: `Bearer ${process.env.CADENCE_ORG_API_KEY}`, "Idempotency-Key": body.idem, }, body: JSON.stringify(body), }); return Response.json(await res.json(), { status: res.status }); }
