Combined with AvailEngine's booking API, you can build a complete multi-tenant booking SaaS product — dashboard, booking widget, and all — in under an hour.\n\n## Why This Works\n\nThe secret is **API-first infrastructure**. Claude Code is exceptional at writing UI code, handling state management, and wiring up API calls. But it's unreliable when asked to generate:\n\n- A Stripe Connect deposit flow with authorization holds\n- HMAC-signed webhooks with exponential backoff retry\n- Row-Level Security for multi-tenant data isolation\n- Rate limiting with per-key counters and billing enforcement\n\nThese are all problems AvailEngine solves before Claude writes a single line of code.\n\n## The One-Hour Build\n\nHere's exactly how to build a booking SaaS with Claude Code + AvailEngine:\n\n### Step 1: Register and Get Your API Key (5 min)\n\n```bash\ncurl -X POST https://api.availengine.com/v1/auth/developer/register \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"email\": \"you@example.com\", \"password\": \"...\", \"first_name\": \"Jane\", \"last_name\": \"Doe\"}'\n```\n\nLog into the dashboard, create a business, and copy your API key.\n\n### Step 2: Give Claude Code This Prompt (30 min work)\n\n```\nBuild a multi-tenant booking SaaS dashboard with Next.js and Tailwind CSS.\n\nBackend: AvailEngine (REST API at https://api.availengine.com)\nAPI Key: avail_test_...\n\nPages needed:\n1. Login/Register page — Supabase auth\n2. Dashboard — list of businesses with booking counts\n3. Business detail — resources, services, availability calendar\n4. Booking widget — embeddable calendar + booking form\n5. Settings — hours, deposits, webhook URLs\n\nUse these endpoints:\n- GET /v1/developer/businesses — list businesses\n- GET /v1/availability/{id}?date=X — check slots\n- POST /v1/bookings/ — create booking\n- GET /v1/manage/bookings — staff view\n- POST /v1/manage/resources — add resource\n\nSandbox business for testing: slug = \"availengine-sandbox\"\n```\n\nClaude Code will generate:\n- A Next.js app with route structure\n- API client with auth headers\n- Calendar/availability components\n- Booking form with validation\n- Admin dashboard views\n\n### Step 3: Test with the Sandbox (10 min)\n\nEvery AvailEngine developer gets a sandbox business pre-loaded with resources and services. You can test the full booking flow — check availability, create a booking, handle the Stripe deposit — without setting up anything.\n\n```bash\n# Check sandbox availability\ncurl \"https://api.availengine.com/v1/availability/availengine-sandbox?date=2026-07-22\"\n\n# Create a test booking  \ncurl -X POST https://api.availengine.com/v1/sandbox/bookings \\\n  -H \"Content-Type: application/json\"\n```\n\n### Step 4: Deploy and Go Live (15 min)\n\nDeploy to Vercel. Create real businesses in the dashboard. Upgrade from Free to Starter (€9.99/mo) when you're ready for production.\n\n## What You Get\n\nAfter one hour, you have:\n\n- ✅ Multi-tenant booking SaaS running on your domain\n- ✅ Stripe deposit handling (authorization holds + no-show capture)\n- ✅ HMAC-signed webhooks for booking lifecycle events\n- ✅ Per-business rate limiting and tenant isolation\n- ✅ Google Calendar two-way sync (Growth+ plans)\n- ✅ Developer dashboard to manage all businesses\n\n## Why Developers Choose This Approach\n\n\"I spent two weeks building a booking system from scratch. Stripe integration alone took three days. With AvailEngine + Claude Code, I rebuilt it in one afternoon and the code was cleaner.\" — AvailEngine developer\n\nThe math is simple: why spend weeks building infrastructure that already exists when you can spend an hour assembling it and focus on the product experience?\n\n## Try It Now\n\n```bash\n# Test the API without signing up\ncurl -X POST https://api.availengine.com/v1/sandbox/bookings \\\n  -H \"Content-Type: application/json\"\n```\n\n[Register for free →](/getting-started) — your sandbox business is waiting.</pre>"}
