Problem

No-shows are the #1 revenue killer for groomers. Customers receive email reminders (24h and 2h before appointments) but have no way to confirm or cancel through the portal or email. The groomer has no signal until the client doesn't show up — by then the slot is wasted and can't be filled.

Priority: P1 — from product backlog (#84), agreed build order: auth (✅ done) → search (#97) → confirmation

Proposed Solution

Customers can confirm or cancel upcoming appointments via two channels:

  1. Customer portal — confirm/cancel buttons on upcoming appointment cards
  2. Email reminder links — tokenized one-click confirm/cancel links in the existing reminder emails

Staff see confirmation status on the admin calendar, giving them advance warning of cancellations and confidence that confirmed clients will show.

Database Changes

Add to the appointments table (or appointment_groups if that's the booking unit):

  • confirmationStatus — enum: pending | confirmed | cancelled (default: pending)
  • confirmedAt — timestamp, nullable
  • cancelledAt — timestamp, nullable
  • confirmationToken — text, nullable, unique — for tokenized email links (no auth required)

API Endpoints

Method Path Auth Purpose
POST /api/appointments/:id/confirm Customer (portal auth) Confirm appointment from portal
POST /api/appointments/:id/cancel Customer (portal auth) Cancel appointment from portal
GET /api/confirm/:token None (tokenized) Confirm via email link
GET /api/cancel/:token None (tokenized) Cancel via email link
  • Token-based endpoints require no authentication — the token itself is the credential
  • Tokens are single-use, scoped to a specific appointment, and expire after the appointment time
  • Portal endpoints validate that the customer owns the appointment
  • Cancellation should respect a configurable cancellation window (default: no restriction for V1, but the field should exist for future use)

Email Changes

Update existing reminder email templates to include:

  • "Confirm Appointment" button/link → /api/confirm/:token (redirects to a confirmation success page)
  • "Cancel Appointment" link → /api/cancel/:token (redirects to a cancellation confirmation page)
  • Token generated when reminder email is sent, stored on the appointment record

Frontend — Customer Portal

  • Upcoming appointment cards show a "Confirm" button (green) and "Cancel" link
  • After confirming: button changes to "Confirmed ✓" (disabled state)
  • After cancelling: card shows "Cancelled" state, appointment removed from active view
  • Cancellation should show a simple confirmation dialog ("Are you sure?")

Frontend — Staff Calendar/Admin

  • Appointment cards show confirmation status indicator:
    • Pending (default) — no indicator or subtle "awaiting confirmation" text
    • Confirmed — green checkmark or "Confirmed" badge
    • Cancelled — visual indicator, appointment visually de-emphasized or struck through
  • Staff can filter appointments by confirmation status (optional, nice-to-have for V1)

Token Generation

  • Generate a cryptographically random token (e.g., crypto.randomUUID() or crypto.randomBytes(32).toString('hex'))
  • Store on the appointment record when reminder email is sent
  • Token is valid only for that specific appointment
  • Token expires after the appointment datetime passes

Acceptance Criteria

  • Customers can confirm appointments from the customer portal
  • Customers can cancel appointments from the customer portal
  • Email reminders include tokenized confirm/cancel links
  • Tokenized links work without authentication (one-click from email)
  • Confirmation status visible on staff calendar/appointment views
  • Cancellation shows a confirmation dialog before proceeding
  • Tokens are single-use and expire after appointment time
  • Works on mobile (screen width ≤ 430px)
  • Unit tests for confirm/cancel endpoints (valid token, expired token, already confirmed, already cancelled)
  • Integration test for the email → token → confirm flow

Out of Scope for This Issue

  • Configurable cancellation window (e.g., "no cancellations within 24h") — field can exist, enforcement deferred
  • Automatic waitlist notification on cancellation (#84, P2 item) — separate feature
  • SMS confirmation — depends on SMS support (#84, P2 item)
  • Rebooking flow after cancellation
  • Staff-initiated confirmation status changes (staff can already manage appointments directly)

Dependencies

  • Existing email reminder infrastructure (PR #29) — ✅ shipped
  • Customer portal (PR #53) — ✅ shipped
  • Role-based API authorization (#88, PR #89) — ✅ merged
  • Quick-find search (#97) — not a hard dependency, but sequenced after per build order

Priority

P1 — Directly reduces no-shows, the groomer's biggest revenue problem. Builds on existing email reminder and customer portal infrastructure. Third feature in the agreed build order.

CTO Technical Review

Well-specified. Architecture aligns with our existing patterns. A few technical notes:

Database:

  • Add columns to the appointments table (not appointment_groups — groups are a booking-time convenience, confirmations are per-appointment).
  • New migration 0012_appointment_confirmation.sql. Add the enum, columns, and a unique index on confirmationToken.
  • confirmationToken should be nullable — only populated when a reminder email is sent.

Token security:

  • Use crypto.randomBytes(32).toString('hex') for tokens — UUIDs are predictable in some implementations.
  • Token-based endpoints (/api/confirm/:token, /api/cancel/:token) should be GET requests that return an HTML page (or redirect to the portal with a success message), not JSON API responses. These are clicked from emails by humans.
  • Rate-limit token endpoints to prevent brute-force token guessing (the token space is large enough that this is theoretical, but defense in depth).

API routes:

  • Portal endpoints (POST /api/appointments/:id/confirm and /cancel) go in the existing appointments router with customer auth middleware.
  • Token endpoints go in a separate routes/confirmation.ts — they're unauthenticated and have different middleware needs.

Email integration:

  • The existing reminder job generates the token and stores it when sending. No separate token generation step.
  • Include the token in the email template URL. The redirect target should be the customer portal with a toast/banner confirmation message.

Frontend:

  • Confirmation status badge on the staff calendar cards — use the same pattern as the existing appointment status indicators.

Sequencing: This comes after #97 (search). Scrubs should complete GRO-134 (search) first.

CTO Architecture Review

Reviewed the codebase and wrote the implementation plan. Key decisions:

Separate confirmationStatus from existing status: The appointments table already has a status field (scheduled/confirmed/in_progress/completed/cancelled/no_show) for the operational lifecycle. Customer confirmation is a separate concern — adding confirmation_status (pending/confirmed/cancelled), confirmed_at, cancelled_at, and confirmation_token columns.

Tokenized endpoints under /api/book/: The public booking routes already bypass auth middleware. Adding GET /api/book/confirm/:token and GET /api/book/cancel/:token here avoids new auth carve-outs.

Token strategy: crypto.randomBytes(32).toString('hex'), generated on appointment creation and when sending reminders (backfill). Single-use for cancellation, idempotent for confirmation. Expires when appointment startTime passes.

Staff calendar: Confirmation status shown as a separate visual layer on appointment cards (green checkmark for confirmed, de-emphasized for customer-cancelled), independent of the existing status color coding.

Portal endpoints: POST /api/appointments/:id/confirm and POST /api/appointments/:id/cancel behind auth for staff/impersonation use.

Implementation delegated to engineering. PR incoming.
