Acuity Scheduling Smart Lock Integration: The Complete Guide for Studio Owners

Does Acuity Scheduling Have a Native Smart Lock Integration?

Not yet. As of 2025, Acuity Scheduling (now part of Squarespace) does not have a built-in integration with any smart lock brand. This is a feature that studio owners have been requesting in the Acuity community forums for years.

However, Acuity does support webhooks — outbound HTTP requests that fire whenever appointments are created, cancelled, or rescheduled. Using webhooks, it's possible to build a real-time integration with smart lock APIs that's just as seamless as if it were built-in.

What You Need for the Integration

To automate door codes with Acuity Scheduling, you need three things:

• An Acuity Scheduling account with webhooks enabled (available on all paid plans)
• A TTLock-based smart lock (sold under brands like Sifely, Gigastone, SMONET, Ardwolf, and others)
• A middleware service to connect them — like Book & Unlock

How the Integration Works

The integration flow is straightforward:

1. 1A client books an appointment on your Acuity booking page.
2. 2Acuity sends a webhook event to Book & Unlock.
3. 3Book & Unlock fetches the full appointment details from the Acuity API.
4. 4A time-limited door code is generated via the TTLock API, valid only during the appointment window.
5. 5The code is emailed and texted to the client automatically.
6. 6When the appointment ends (or if it's cancelled), the code expires or is deleted.

Supported Smart Lock Brands

The TTLock platform is the most widely used API-accessible smart lock ecosystem for residential and commercial use. Dozens of brands manufacture TTLock-compatible hardware:

• Sifely — popular with studio owners, reliable battery life, clean design
• TTLock — the reference brand, widely available
• Gigastone — budget-friendly option
• SMONET — commercial-grade models available
• Ardwolf — known for durable construction
• Veise — good fingerprint + keypad combos
• Turbolock, Kaadas, Lockin, Sciener — and many more

If your lock uses the TTLock app or a white-label variant of it (like the Sifely app), it will work with this integration.

DIY vs. Using Book & Unlock

Technically, you could build this integration yourself. You'd need to set up a server to receive webhooks, authenticate with both the Acuity and TTLock APIs, handle retries, manage token refresh cycles, and build the email/SMS delivery pipeline. For a developer, this is a weekend project.

For a studio owner, it's not worth the time — or the ongoing maintenance. Book & Unlock handles all of this for $15–$35 per month, depending on your usage. That's less than the value of a single hour of your time.

Studio owners in the Acuity community forums have been asking for this exact integration for years. Book & Unlock is the answer.

Step-by-Step Setup

1. 1Sign up for Book & Unlock and start your 7-day free trial.
2. 2Connect your Acuity account via OAuth — one click, no API keys.
3. 3Enter your TTLock credentials (the email and password you use in the TTLock or Sifely app).
4. 4Fetch your locks from your TTLock account and give each one a name.
5. 5Map your Acuity appointment types to the appropriate lock.
6. 6Copy your unique webhook URL from the Book & Unlock dashboard and paste it into Acuity's webhook settings.
7. 7Test with a real or test booking — your client will receive a code automatically.

What About Squarespace Scheduling?

Acuity Scheduling was acquired by Squarespace and is now also sold as Squarespace Scheduling. The product is the same — the webhooks work identically. If you have a Squarespace Scheduling account on a paid tier, this integration works exactly the same way.
