Learn how to integrate with Boulevard, a tool that assists salon and spa brands with booking, scheduling, marketing, payments, reporting, and more.

Before you begin

Before you begin, confirm that you have access to the Boulevard API. This integration relies on Boulevard Webhooks and APIs, which require a subscription to the Boulevard API package. If you are unsure if you have this package, contact your Boulevard CSM to confirm.

Integrate Boulevard with Klaviyo

To integrate Boulevard with Klaviyo:

In the Boulevard console, navigate to Manage Business > App & Integration.

In Klaviyo, select the Integrations tab.
Click Explore apps, then search for Boulevard and select the card.
On the next page, click Install.
Enter your Boulevard Business ID and click Connect.

Review the permissions and click Allow.
On the next page, if you want to sync email subscribers, check the box to Sync your Boulevard email subscribers to Klaviyo.
Select a Klaviyo list from the dropdown for these subscribers.
If you want to sync SMS subscribers, check the box to Sync your Boulevard SMS subscribers to Klaviyo.
Select a Klaviyo list from the dropdown for these subscribers. We recommend keeping separate lists for email and SMS.
When you’re done, click Save.

You’ve now integrated Boulevard with Klaviyo.

Understand your Boulevard data

Klaviyo syncs client data and events related to appointments, memberships, and orders from Boulevard. When you integrate, Klaviyo imports historical records for these types of data, then syncs ongoing data in real time. Historical appointment and membership events do not recreate every past status change.

To view your Boulevard data in Klaviyo:

Click the Analytics dropdown in the left-hand navigation sidebar.
Select Metrics. Here, you can view all of the metrics in your account. The metrics with a Boulevard icon represent all of the metrics synced from your Boulevard integration.
Filter this view to see only Boulevard metrics by using the filter selector next to the search bar.

Learn more about your Boulevard data.

Segment customers using Boulevard data

You can use Boulevard’s metrics to segment customers and target them with a campaign. For example, you can create a segment of everyone who has completed an appointment in the last 30 days and send a campaign to that segment.

To create the example segment shown above:

Click the Audience dropdown in the left-hand navigation sidebar.
Click Lists & segments.
Click Create in the top right.
Select Segment.
Name your segment and select tags if desired. If these fields appear in a dialog, click Create segment to open the segment builder.
Under Definition, select What someone has done (or not done) > Completed Appointments > at least once > in the last > 30 > days. If you have multiple integrations, make sure to choose the Completed Appointments metric with the Boulevard logo.
Click Create segment.

To limit this segment to people who completed an appointment for the first time in the last 30 days, open the segment and click Edit definition. Then:

Click AND to add another condition.
Add the condition What someone has done (or not done) > Completed Appointments > equals > 1 > over all time. This will exclude anyone who has completed an appointment more than once.

Click Update segment.

Use Boulevard data in flows

You can use Boulevard metrics to trigger flows. For example, use the Completed Appointments metric to trigger a flow to send messages to someone immediately when they complete an appointment.

If you are using Boulevard to send email and SMS notifications, make sure to turn off messages that you would rather send through Klaviyo flows so that your customers aren’t receiving repetitive messages. See Boulevard’s support documentation for more information on how to disable email and SMS notifications.

To create a flow using Boulevard metrics:

Navigate to the Flows tab from the left-hand navigation sidebar.
Click Create flow in the top right.
Click Build your own in the top right.
Name your flow and select tags if desired.
Select Create manually. If you see a Create flow button instead, click it.
In the flow builder, select Your metrics, then Boulevard.
Select a Boulevard metric, such as Completed Appointments, indicated by the Boulevard icon.

Click Save, then Confirm and save.
Add a message relevant to the triggering action, such as a thank you message.

Once your content is ready, click Review and turn on in the top right of the flow builder.
Set Flow status to Live and click Save.
