What Are Integrations in HighLevel?

Integrations in HighLevel are the connections between HighLevel and external platforms and services. They are what enables HighLevel to pull in data from Google, publish to Facebook, process payments through Stripe, sync with QuickBooks, and connect to thousands of other tools through Zapier and the API.

Without integrations, HighLevel operates as a standalone system – capable within its own walls but disconnected from the broader technology ecosystem the business uses. With integrations, HighLevel becomes the hub that connects to and coordinates data across the business’s complete technology stack.

Most integrations are managed at Settings, then Integrations in the sub-account.

Where to Find and Manage Integrations

The primary integrations interface is at Settings, then Integrations in the sub-account. This page lists the available native integrations with connection status – which are connected, which are disconnected, and which have not been set up.

Click any integration to begin the connection process or manage an existing connection.

Some integrations are also configured in specific feature settings rather than the central Integrations page – payment integrations are sometimes in the Payment Settings, social media connections may appear in the Social Planner settings, and calendar sync settings are in the Calendar configuration. The central Integrations page covers most connections, but some feature-specific integrations have their own configuration location.

Google Integrations

HighLevel’s Google integrations are among the most commonly used and cover several distinct capabilities. Each requires a Google account connection but enables different features.

Google Business Profile: Connecting a GBP enables reputation management (viewing and responding to reviews from HighLevel), GBP social posts through the Social Planner, Google My Business messaging, and the local SEO audit features. The GBP connection is one of the most impactful integrations for local service businesses.

Google Ads: Connecting Google Ads enables conversion tracking, audience sync, and the Google Ads integration features including automated ad management and attribution reporting. This connection is needed for any paid search advertising managed through HighLevel.

Gmail / Google Workspace: Connecting a Gmail or Google Workspace account enables using that email address for sending and receiving individual emails through the Conversations Inbox. This is the connected email account for individual correspondence – distinct from LC Email which handles bulk sends.

Google Calendar: Connecting Google Calendar syncs HighLevel appointments to a personal or team Google Calendar, and optionally allows Google Calendar availability to influence HighLevel booking page availability. Team members can see their HighLevel appointments alongside personal calendar events.

Facebook Integrations

Facebook integrations in HighLevel connect through the Facebook Business Manager OAuth flow and cover several distinct capabilities under one connection.

Facebook Page: Connecting a Facebook Page enables Facebook Messenger conversations in the Conversations Inbox, social media posting to the Facebook Page via the Social Planner, and Facebook reviews appearing in the Reputation dashboard. One Facebook Page connection enables multiple features simultaneously.

Facebook Lead Ads: Enabling the Facebook Lead Ads integration allows leads captured through Facebook Lead Ad forms to flow directly into HighLevel as contacts, triggering any configured lead intake workflows. The Lead Ads integration is configured within the Facebook connection – select the Lead Ad forms to sync.

Instagram: Instagram Business accounts are connected through the Facebook Page OAuth – Instagram must be linked to a Facebook Page in Meta’s Business settings before it can be connected to HighLevel. Once connected, Instagram posts can be scheduled through the Social Planner and Instagram conversations may appear in certain configurations.

Payment Integrations

HighLevel’s payment integrations connect the invoicing, subscriptions, and product catalog features to actual payment processing infrastructure. The primary payment integrations are Stripe, PayPal, and Venmo.

Stripe is the most commonly used payment integration. Connecting a Stripe account enables accepting credit and debit card payments through HighLevel funnels, payment forms, and invoices.

Stripe is also required for HighLevel’s subscription billing features. Most agencies and businesses using HighLevel for payments use Stripe as the primary processor.

PayPal and Venmo are also available as payment options when configured. These provide an alternative payment method that some customers prefer over credit cards.

The payment integration settings allow enabling multiple payment methods so customers can choose their preferred option at checkout.

Accounting Integrations

HighLevel’s QuickBooks integration allows syncing invoice and payment data from HighLevel’s invoicing system to QuickBooks Online. When an invoice is created or paid in HighLevel, the data can be automatically pushed to QuickBooks – reducing the manual data entry required to maintain accurate accounting records.

For businesses that use HighLevel for invoicing and QuickBooks for accounting, the integration eliminates a common data entry bottleneck. Invoice creation in HighLevel and reconciliation in QuickBooks are connected – the data flows between them without requiring someone to manually enter invoice information in both systems.

Zapier Integration

Zapier is the integration bridge that connects HighLevel to thousands of apps that do not have a direct native integration. When a business uses a tool that HighLevel does not natively connect to – a specific project management app, a specialized industry software, a custom CRM, a data warehouse – Zapier is how HighLevel connects to it.

In Zapier, HighLevel is available as both a trigger app (a HighLevel event starts a Zap) and an action app (a Zap performs an action in HighLevel). HighLevel trigger events in Zapier include: contact created, form submitted, appointment scheduled, opportunity stage changed, tag added, and others.

HighLevel action capabilities include creating or updating contacts, adding tags, and triggering workflows.

The Zapier integration requires a HighLevel API key (available in Settings, then API and Keys) to authenticate the connection. Once connected in Zapier, building individual Zaps requires no coding – just selecting triggers and actions from Zapier’s visual interface.

API and Webhooks

Beyond native integrations and Zapier, HighLevel provides a full REST API and Webhook system for custom integrations. The API allows developers to build direct connections between HighLevel and any external system – creating contacts, reading contact data, triggering workflows, and managing sub-accounts programmatically.

Webhooks allow HighLevel to push data to external endpoints in real time when events occur. A webhook configured for “contact created” fires a POST request to the specified URL every time a new contact is added – enabling real-time data sync with custom systems, third-party analytics tools, or any platform that accepts webhook data.

The API and Webhooks are covered in detail in the dedicated API and Webhooks post. For the majority of integration needs, native integrations or Zapier are sufficient without requiring custom API development.

Keeping Integrations Healthy

OAuth-based integrations – most Google and Facebook connections – expire when the connected account’s password changes, when the granted permissions are revoked, or when the platform’s token expires for security reasons. Expired connections silently stop working – features that depend on them fail without a clear error message.

The most common symptoms of an expired integration: Google reviews stop appearing in the Reputation dashboard, Facebook Lead Ads stop flowing into HighLevel as contacts, social media posts fail to publish, or GBP review responses fail to post. When these features stop working unexpectedly, checking the Integrations section for expired connections is the first diagnostic step.

A monthly integrations health check – opening Settings, then Integrations and scanning the connection status of all active integrations – takes 2 minutes and prevents the frustration of discovering a broken integration when a feature fails at a critical moment. For agencies managing multiple client sub-accounts, including an integrations health check in the monthly client maintenance routine is good practice.

What Can You Do With It?

• Connect Google Business Profile to enable reputation management, GBP posts, and local SEO features: A single GBP connection unlocks multiple features – review display and response, social posting to GBP, GBP messaging, and local SEO audit tools. One connection, multiple HighLevel capabilities.
• Sync Facebook Lead Ads directly to HighLevel contacts and workflows: Facebook Lead Ads leads flow into HighLevel automatically when the Facebook integration is configured – no manual export/import, no data entry lag. Leads captured on Facebook are in HighLevel within seconds.
• Process payments through Stripe on funnels, forms, and invoices: Connecting Stripe enables end-to-end payment collection through HighLevel – from lead capture to invoice payment – without a separate payment platform or manual payment reconciliation.
• Connect HighLevel to any app not natively supported via Zapier: The Zapier integration extends HighLevel’s connectivity to 5,000+ additional apps – enabling data flows and automations between HighLevel and any tool in the business’s technology stack.
• Sync HighLevel appointment and invoicing data with Google Calendar and QuickBooks: Team calendar visibility and accounting accuracy both improve when HighLevel data flows to the platforms where that data is managed – without manual re-entry.

Key Definitions

Use Cases by Industry

Home Services – Full Integration Stack

A plumbing company’s HighLevel sub-account has the following integrations active: Google Business Profile (for reputation management and GBP posts), Google Ads (for conversion tracking from their paid search campaigns), Gmail (for individual customer email replies through the Conversations Inbox), Stripe (for invoice payments), and Facebook (for Messenger and social posting).

Together these integrations make HighLevel the central hub of the business’s technology – customer reviews flow in from Google, ads convert and track through Google Ads, payments process through Stripe, and social communication flows through Facebook. The business manages all of this from one platform without logging into each service separately for day-to-day operations.

Result: HighLevel becomes the operational center of the business’s digital presence. Five separate platform logins reduced to one daily platform check – everything flows to HighLevel through integrated connections.

Marketing Agency – Client Integration Onboarding

An agency’s client onboarding checklist includes an integration setup step for every new client. After importing the snapshot, the account manager connects the client’s Google Business Profile, Facebook Page, and Stripe account using the client’s credentials.

This single setup session activates reputation management, social posting, lead ads, and payment processing simultaneously.

The agency’s onboarding documentation includes screenshots of the expected integration status after setup – making it easy to verify all connections are active before completing onboarding. A monthly integrations health check is included in the agency’s client maintenance process.

Result: Client sub-accounts have all necessary integrations active from day one. The structured onboarding process prevents the common situation where a client goes weeks without reviews appearing because the GBP connection was never set up.

E-Commerce Store – Zapier to Fulfillment

An online retailer uses HighLevel for sales funnels and order capture. Their fulfillment software does not have a native HighLevel integration.

They use Zapier: when a HighLevel opportunity moves to “Order Confirmed” stage, a Zap fires and creates a fulfillment order in their warehouse management system with the order details from the HighLevel contact record.

The integration runs silently in the background – every confirmed order in HighLevel automatically creates a fulfillment record in the warehouse system within seconds. No manual data entry, no missed orders, no fulfillment delays from data lag.

Result: Sales operations in HighLevel and fulfillment operations in a specialized tool are connected through Zapier without any custom coding. HighLevel remains the sales and CRM system; the fulfillment system handles what it does best. Zapier handles the handoff automatically.

Who Is This For?

How to Connect an Integration

Step 1: Navigate to Integrations

Settings, then Integrations in the sub-account. The integrations list loads with connection status for each.

Step 2: Select the integration

Find and click the integration to connect – Google, Facebook, Stripe, QuickBooks, or another available option.

Step 3: Complete the OAuth flow

Click Connect. An authorization window opens from the third-party platform.

Log in with the correct account credentials and grant the requested permissions.

Step 4: Select the specific account or profile

For multi-account integrations (multiple Facebook Pages, multiple Google accounts), select the specific one relevant to this sub-account. Connect the client’s account, not the agency’s personal account.

Step 5: Verify the connection

Confirm the integration shows as connected in the Integrations settings. Check that the correct account name is displayed.

Step 6: Test the integration

Test with a small action – check if reviews appear in Reputation, if a test lead ad form submission flows into contacts, or if a test payment processes through Stripe.

Step 7: Set up Zapier for non-native integrations

For platforms without a direct native integration, go to Settings, then API and Keys, generate a HighLevel API key, and use it to connect HighLevel as an app in Zapier. Build the desired Zap using Zapier’s visual interface.

Step 8: Set a monthly integration health check reminder

Add a recurring monthly task to check the Integrations page for any expired or disconnected connections. Reconnect anything that has lapsed.

Step 9: Include integration setup in sub-account onboarding checklists

For agencies, add integration setup as a standard step in the client onboarding checklist. List which integrations are required for which features and verify all are connected before marking onboarding complete.

How Does It Connect to HighLevel?

• Google Business Profile Integration: The GBP integration powers Google Business Profile features – reputation management, GBP posts, GBP messaging, and local SEO tools. Without the GBP connection, none of these features work.
• Facebook Lead Ads Integration: The Facebook integration enables Facebook Lead Ads to flow directly into HighLevel contacts and workflows. The integration also powers Facebook Messenger in Conversations and Facebook social posting.
• Payment Integrations: Payment Integrations (Stripe, PayPal, Venmo) are configured through the integrations system. Without a payment integration connected, HighLevel’s invoicing, subscription billing, and checkout features cannot process actual payments.
• API and Webhooks: The API and Webhooks system is the developer-level integration layer – extending connectivity beyond what native integrations and Zapier cover for custom or complex integration requirements.
• Social Planner: The Social Planner depends on the Facebook, Instagram, Google Business Profile, and LinkedIn integrations to function. Social publishing requires active, non-expired connections to each target platform.

Common Questions

Where do I manage Integrations in HighLevel?

Settings, then Integrations in the sub-account. Some feature-specific integrations also appear in their respective settings areas.

What platforms can HighLevel integrate with?

Google (GBP, Ads, Gmail, Calendar), Facebook (Pages, Lead Ads, Instagram, Messenger), Stripe, PayPal, Venmo, QuickBooks, Zapier, and more. API and Webhooks enable custom connections to any platform.

How does the Zapier integration work with HighLevel?

HighLevel connects to Zapier via API key. In Zapier, HighLevel appears as both a trigger app (HighLevel events start Zaps) and an action app (Zap actions update HighLevel).

Enables connections to 5,000+ apps without native HighLevel integrations.

Does HighLevel integrate with Google Calendar?

Yes. Google Calendar sync allows HighLevel appointments to appear in a connected Google Calendar. Configured through the calendar settings in the sub-account.

Can HighLevel integrate with accounting software like QuickBooks?

Yes. The QuickBooks integration syncs invoice and payment data from HighLevel’s invoicing system to QuickBooks Online – reducing manual data entry.

What is the difference between native integrations and API/Webhooks in HighLevel?

Native integrations are pre-built connections configured with OAuth or API key clicks. API and Webhooks are the developer-level layer for custom integrations with any platform – more flexible but requiring technical implementation.

To Wrap It Up

Integrations are what transforms HighLevel from a capable standalone platform into a connected hub at the center of a business’s digital operations. Without them, HighLevel handles what it handles.

With them, HighLevel connects to and coordinates with everything else the business uses.

The integrations most businesses need from day one are the ones that enable core features: Google Business Profile for reputation management, Facebook for Lead Ads and Messenger, and Stripe for payments. These three connections unlock the most commonly used HighLevel capabilities that depend on external connections.

Getting them set up correctly during initial sub-account configuration prevents the most common “why isn’t this feature working?” questions.

The integration health habit is simple and high-value: a two-minute monthly check of the Integrations page to confirm all connections are active. The cost of the check is two minutes.

The cost of discovering an integration expired three weeks ago, after the feature silently failed for those three weeks, is far higher – in lost leads, missed reviews, or payment failures.

1. Navigate to Settings, then Integrations in the sub-account
2. Connect the Google Business Profile via OAuth
3. Connect the Facebook Page via OAuth – this also enables Instagram, Messenger, and Lead Ads
4. Connect Stripe for payment processing
5. Connect Gmail or Google Workspace for the Conversations Inbox email account
6. Connect Google Calendar for appointment sync if the team uses Google Calendar
7. Connect QuickBooks if the business uses HighLevel invoicing alongside QuickBooks accounting
8. Set up Zapier connections for any tools not covered by native integrations
9. Set a monthly reminder to check and renew any expired connections

Include integration setup in the agency’s client onboarding checklist as a required step – not an optional one. Every feature that depends on an integration fails silently when the integration is missing.

A checklist that verifies all required integrations are connected before marking onboarding complete prevents the support calls that arise when a client asks why their Facebook leads are not coming into HighLevel three weeks after go-live.
