A Guide to Boulevard Integrations: Apps, Software, APIs

Explore Boulevard integrations for QuickBooks, Shopify, Zapier, Google Calendar, marketing, APIs, AI booking, and more for salons, spas, and med spas.

Boulevard is more than an appointment calendar. For salons, spas, med spas, barbershops, and other self care businesses, it can act as the central system behind scheduling, client information, payments, marketing, and daily operations.

But most businesses do not operate with one platform alone.

You may use QuickBooks for accounting, Shopify for e-commerce, Google Calendar for personal scheduling, Klaviyo for marketing, Google for customer acquisition, and other tools for reviews or automation.

That is where Boulevard integrations become important.

Boulevard offers native integrations with several popular business applications. It also supports workflow automation through Zapier. Enterprise businesses can go further through Boulevard's APIs and custom applications.

This guide explains what integrates with Boulevard, how different integration methods work, which connections are useful for salons and med spas, and when you may need Zapier, an API, or an AI booking integration.

What Is a Boulevard Integration?

A Boulevard integration connects Boulevard with another application so information or actions can move between the two systems.

A simple integration might synchronize appointments between Boulevard and Google Calendar.

A more advanced integration could send completed Boulevard sales into accounting software, update an ecommerce inventory system, trigger a review request, add a client to a marketing campaign, or allow another application to interact with Boulevard booking data.

The goal is simple: reduce manual work while keeping Boulevard at the center of the client journey.

For an appointment based business, that can mean fewer duplicated records, faster follow up, cleaner reporting, and less time switching between systems.

What Does Boulevard Integrate With?

Boulevard's current integration ecosystem covers several major business functions.

Its official catalog includes connections involving:

Google Calendar
Apple Calendar
QuickBooks Online
Shopify
Reserve with Google
Facebook Book Now
Instagram Book Now
Klaviyo
Zapier
OPERA PMS
Okta SSO
REACH.ai
Vish
Widewail
Green Circle Salons

Availability can depend on your Boulevard subscription and the integration you want to use. Some apps are available across Boulevard plans, while other integrations require Premier, Prestige, or Enterprise access.

The important distinction is that not every Boulevard connection works in the same way.

The 3 Main Ways to Integrate Boulevard

There are three practical integration routes.

1. Native and Partner Integrations

The easiest option is usually an integration already supported by Boulevard.

These integrations are designed for specific workflows such as accounting, calendars, ecommerce, social booking, or review generation.

Because the connection is already defined, businesses generally have less data mapping and technical work to manage.

2. Boulevard and Zapier

Zapier acts as an automation layer between Boulevard and other applications.

A Boulevard event can act as a trigger. Another application can then perform an action.

For example, a new Boulevard client could be added to a marketing platform. A completed order could create a row in Google Sheets. A new appointment could create an external calendar event.

Boulevard states that its Zapier integration can also be used for workflows involving platforms such as HubSpot, Klaviyo, SurveyMonkey, Birdeye, Slack, and Google Drive.

3. Boulevard API and Custom Integrations

Businesses with more complex requirements can use Boulevard's developer platform.

Boulevard provides APIs for building custom applications and booking experiences. Its developer documentation includes an Admin API, Client API, webhook capabilities, and tools for custom booking workflows.

Direct API access and custom applications are primarily an Enterprise capability. Boulevard also allows qualifying customers to install supported public applications through the Apps & Integrations area.

This makes the API route better suited to businesses that need functionality beyond standard no code automations.

Most Useful Boulevard Integrations

Boulevard Shopify Integration

The Boulevard Shopify integration is especially useful for salons, spas, and med spas that sell retail products both in person and online.

Boulevard's official Shopify app can synchronize products and inventory between Shopify and Boulevard. It also supports gift card synchronization in qualifying configurations. Boulevard notes that Shopify Plus is required for its gift card sync.

Inventory quantity updates can move between the two platforms.

For example, if a skincare product is sold at your front desk, the available quantity can update in Shopify. If the same product sells through your ecommerce store, Boulevard can reflect the inventory change.

This prevents a common problem for beauty businesses: maintaining one stock count for the physical location and another for ecommerce.

Boulevard Google Calendar Integration

Boulevard offers a two way personal calendar connection with Google Calendar.

Boulevard appointments can appear on the connected calendar. Personal events created in the external calendar can also block corresponding time inside Boulevard so clients cannot book unavailable periods.

This is useful for providers who manage both professional appointments and personal obligations.

It can be particularly valuable for:

Independent providers
Injectors
Salon owners
Medical directors
Providers working across locations
Professionals with outside meetings or training

The main benefit is not simply seeing two calendars.It is preventing availability conflicts.

Boulevard Apple Calendar Integration

Apple Calendar works in a similar way. Professionals can view Boulevard appointments alongside personal calendar events. Personal commitments can block availability inside Boulevard when the calendars are properly synchronized.

For providers who work mainly within the Apple ecosystem, this can make schedule management easier without requiring them to constantly open Boulevard.

Boulevard Instagram and Facebook Book Now

Social media is another major discovery channel for beauty and aesthetics businesses.

Boulevard supports Book Now functionality for Facebook and Instagram business profiles. The button can open Boulevard's self-booking experience and allow a potential client to schedule from the social discovery journey.

For businesses generating demand through before and after content, treatment education, hairstyle content, or promotional campaigns, this reduces friction.

Instead of:

Instagram → website → service page → booking page

the journey can become:

Instagram → booking

Every extra step removed from a high intent journey can make booking easier.

Boulevard Klaviyo Integration

Marketing becomes much stronger when it understands what a client actually does.

Boulevard's Klaviyo integration can make customer, service, booking, and transaction information available for more personalized marketing workflows.

Boulevard describes use cases including segmentation based on service history, preferences, and booking behavior. It can also help connect campaign performance with actual bookings. The current Boulevard catalog lists this direct Klaviyo integration for Enterprise accounts.

This creates useful campaigns such as:

Treatment follow-ups
Rebooking reminders
Skincare replenishment reminders
Lapsed client campaigns
Service specific promotions
Post appointment messages
Client segment promotions

For a med spa, someone who previously booked Botox should not receive exactly the same sequence as someone who only booked laser hair removal. Integration makes that level of segmentation easier.

Clara and Boulevard Integration

Boulevard manages appointments, client records, payments, and day to day med spa operations. Clara, a voice AI Receptionist for MedSpas, adds a voice AI layer to that workflow by handling incoming phone calls and booking appointments directly into Boulevard.

When a client calls, Clara can check real time Boulevard availability for the requested treatment and provider. It can offer available appointment times and place the confirmed booking directly on the Boulevard calendar while the caller is still on the phone. This removes the need for front desk staff to manually transfer information from voicemail or another system.

Clara can also be configured around the med spa's:

Treatment menu
Pricing ranges
Providers
Booking rules
Practice policies
Call routing preferences

This means someone calling about Botox pricing, laser hair removal, fillers, or another treatment can receive information based on the med spa's actual services rather than a generic call script.

The integration is particularly useful for calls that arrive after hours, during treatments, or while the front desk is already helping another client. Clara answers calls 24/7, checks Boulevard availability, and can turn the conversation into a confirmed appointment rather than leaving the caller with voicemail.

For med spas handling protected health information, Clara is HIPAA compliant and signs a Business Associate Agreement with the med spas it works with. According to Clara, most Boulevard integrations can be configured and live within 24 to 48 hours.

When to use Clara with Boulevard

A Clara and Boulevard integration makes sense when Boulevard already handles your scheduling, but phone calls are still creating a gap in the booking journey.

Instead of:

Phone call → voicemail → staff callback → availability check → appointment

the workflow can become:

Phone call → Clara → live Boulevard availability → confirmed appointment

Boulevard remains the scheduling and client management platform. Clara handles the phone conversation and connects callers with the same Boulevard calendar your team already uses.

Does Boulevard Integrate With HubSpot?

Boulevard's official integration documentation specifically references HubSpot as one of the applications that can be used within Zapier based workflows.

That is different from saying Boulevard has a full native HubSpot integration. The distinction matters. If you want Boulevard data in HubSpot, first define what data needs to move and in which direction.

For example:

New client created
Appointment booked
Appointment completed
Order completed
Contact updated
Marketing status changed

Then confirm whether Boulevard and HubSpot expose the required Zapier trigger and action.

Does Boulevard Integrate With Mailchimp?

Mailchimp workflows are available through Boulevard's Zapier ecosystem.

One example is adding or updating Mailchimp subscribers when clients are created in Boulevard.

This can help businesses keep email audiences synchronized without manually exporting client lists.

However, always account for marketing consent before subscribing clients to promotional communications.

Boulevard API: What Can You Build?

Not every workflow fits inside a ready made integration.

That is where the Boulevard API becomes useful.

Boulevard's developer platform exposes APIs that allow qualified businesses and developers to build custom applications and experiences.

Its Client API can support custom booking experiences. Boulevard documentation describes functionality for displaying services, finding availability, and completing bookings.

The Admin API provides access to operational business data and also supports webhooks.

Webhooks allow another application to react when an event occurs instead of repeatedly checking Boulevard for changes.

This creates possibilities such as:

Custom booking interfaces
Internal dashboards
Business intelligence systems
Advanced marketing workflows
Client synchronization
Custom appointment automation
Multi location workflows
AI powered booking applications
Custom reporting
Specialized industry applications

Is the Boulevard API Available on Every Plan?

No. Boulevard's developer documentation states that its public APIs and custom apps are available to Enterprise tier customers. Boulevard separately allows supported public applications to be installed by qualifying accounts through its Apps & Integrations system.

This distinction is important when evaluating an integration provider. An integration that works through an approved public app may have different access requirements from a custom application your business builds itself.

Always confirm plan requirements before designing a workflow around API access.

Can Boulevard Integrate With an AI Receptionist?

Yes. AI receptionists are becoming another integration category for appointment based businesses.

A Boulevard connected AI receptionist can be used to handle incoming calls while using Boulevard as the scheduling system.

Instead of simply taking a message, the system can potentially check appropriate appointment availability and move qualified callers toward a real booking, depending on the permissions and integration implementation.

For med spas using Boulevard, Clara AI provides a 24/7 voice AI receptionist designed to answer treatment inquiries and book appointments into Boulevard. It is useful when the operational problem is not online booking, but unanswered or after hours phone demand.

That allows Boulevard to remain the booking platform while an AI layer handles another part of the patient journey.
