Your receptionist just typed a new lead’s name, phone, and address from HighLevel into ServiceTitan. She transposed two digits. Your tech drives past the house twice, the customer calls back angry, and a $900 repair nearly walks out the door.

The Short Answer: Yes, But You Need a Translator

Here’s the thing: HighLevel captures leads, ServiceTitan dispatches techs, and neither tool was built to talk to the other.

The consensus online is correct: no widely supported, one-click connection between HighLevel and ServiceTitan is advertised by either platform at the time of writing. Check both platforms’ integration marketplaces to confirm before you build — this space moves fast. Most forum threads point you toward a premium Zapier account and webhooks. That works, but it’s expensive at volume.

The counter-perspective is also worth hearing. Contractors who have tried building a perfect two-way sync between the two platforms report getting stuck in infinite loops. A change in GHL fires a webhook to ServiceTitan, which triggers an update back to GHL, which fires again. The practical answer lands between these positions: you need a one-way bridge for each direction, not a two-way sync.

HighLevel is a CRM (customer relationship management tool) and marketing platform. It captures leads from ads, missed calls, web forms, and text campaigns. ServiceTitan is dispatch and field service management software. It schedules jobs, routes techs, and tracks invoicing.

Make.com acts as the translator. Its HTTP module sends requests directly to ServiceTitan’s documented API, and its HighLevel module listens for new contacts or status changes. For a full walkthrough of how Make connects to ServiceTitan’s API, see our guide on how to integrate ServiceTitan with Make.com in 4 steps.

Make’s free tier gives you 1,000 credits per month. For most contractors handling 20-50 new leads weekly, the Core plan at around $9-10/month (billed annually) covers the volume.

Prerequisites

Before you start, confirm you have:

• A HighLevel account (Starter plan at $97/month or higher; note that usage-based charges for SMS and calls add to this)
• A ServiceTitan account with API access enabled (you need to request API credentials from your ServiceTitan account manager; approval typically takes 3-7 business days)
• A Make.com account (free tier works for testing; paid plans start around $9-10/month billed annually)
• Your ServiceTitan Tenant ID and API key (found in your ServiceTitan developer portal after approval)

Workflow 1: Getting HighLevel Leads Into ServiceTitan

The upshot: new leads land in ServiceTitan’s booking board without anyone retyping a phone number.

This workflow fires every time a new contact enters HighLevel. Make.com picks it up and creates a matching customer record in ServiceTitan. When using the webhook trigger, data moves in seconds rather than waiting for a scheduled poll.

Step 1: Create a New Scenario in Make.com

Log into Make.com and create a new scenario. Add the HighLevel module as your trigger. Select “Watch New Contact” as the trigger event. Authenticate with your GHL API key.

Expected outcome: Make.com shows a green checkmark and pulls in a sample contact from your GHL account. Time: ~5 minutes.

Add an HTTP “Make a Request” module after the GHL trigger. Set the method to POST. Your target URL is ServiceTitan’s Customer Create endpoint from their API documentation.

ServiceTitan uses OAuth 2.0 for authentication — not a simple API key in a header. Here is what that means in practice:

1. In your ServiceTitan developer portal, create an app and obtain a Client ID and Client Secret.
2. Make a POST request to https://auth.servicetitan.io/connect/token with your Client ID, Client Secret, and grant type client_credentials. ServiceTitan returns a short-lived access token.
3. In your HTTP module headers, set Authorization: Bearer {access_token} and add ST-App-Key: {your_app_key} as a second required header.

Make.com handles token refresh automatically if you use its built-in OAuth 2.0 connection type. Set that up in Make’s Connections panel rather than hardcoding tokens, or your scenario will start failing when the token expires (typically every hour).

Expected outcome: The module appears connected with POST method, OAuth headers, and your app key configured. Time: ~15 minutes.

Step 3: Map Your Fields (This Is Where Most People Break Things)

Map GHL fields to ServiceTitan fields. Name and phone number map cleanly. The address field does not.

This is the step that quietly destroys technician routing. GHL stores addresses as a single text string: “4281 Oak Ridge Dr, Tampa, FL 33610.” ServiceTitan expects separate fields: street, city, state, zip. If you dump the full GHL address string into ServiceTitan’s street field, the GPS routing your technician relies on will fail silently. The job looks booked. The address looks right at a glance. But the tech ends up circling the neighborhood because ServiceTitan’s mapping engine cannot parse a combined string.

The fix: Use Make.com’s built-in text parser. Add a “Split Text” function between the GHL module and the HTTP module. Split the GHL address on commas. Then map: position 1 to street, position 2 to city, position 3 (split again on space) to state and zip separately.

Expected outcome: Your ServiceTitan test customer has a clean, properly separated address. Time: ~20 minutes for mapping, including address parsing.

Add an error handler to the HTTP module. Set it to email or Slack you if a request fails. Common failures: duplicate phone numbers (ServiceTitan rejects them), expired OAuth tokens, or malformed addresses.

Turn on the scenario and set it to run immediately on trigger, since this workflow fires on each new GHL contact event.

Expected outcome: The next lead that enters GHL automatically appears in ServiceTitan’s customer list within seconds. Time: ~10 minutes.

Workflow 2: Syncing Completed Jobs Back to HighLevel

The first workflow handles marketing-to-dispatch. This one closes the loop by pushing completed job data from ServiceTitan back into HighLevel so you can trigger review requests, upsell campaigns, and revenue reporting without lifting a finger.

Step 1: Set Up a ServiceTitan Webhook (or Scheduled Poll)

ServiceTitan’s API supports webhooks for certain events, but availability depends on your plan and API tier. If webhooks are available:

1. In Make.com, create a new scenario
2. Add a Webhooks > Custom Webhook module as your trigger
3. Copy the webhook URL and register it inside ServiceTitan under Settings > API > Webhooks
4. Select the Job Completed event

If webhooks are not available on your ServiceTitan plan (common on lower tiers), use a scheduled HTTP module instead:

1. Add an HTTP > Make a Request module
2. Point it to GET https://api.servicetitan.io/jpm/v2/tenant/{tenant_id}/jobs
3. Add a filter parameter: completedAfter set to the timestamp of your last poll
4. Schedule the scenario to run every 15–30 minutes

Step 2: Update the Contact in HighLevel

Once the job data comes in, match it to the right HighLevel contact and update their record. HighLevel’s API uses LeadConnector endpoints — you can find the full reference at HighLevel’s developer documentation:

1. Add an HTTP > Make a Request module
2. Search for the contact: GET https://services.leadconnectorhq.com/contacts/search?query={phone_number}
3. Add the required headers: Authorization: Bearer {your_GHL_private_api_key} and Version: 2021-07-28
4. Match on phone number — the most reliable shared identifier between the two systems
5. Once matched, update the record: PUT https://services.leadconnectorhq.com/contacts/{contactId} with the same Authorization and Version headers

These are example endpoints based on the current LeadConnector API. Verify paths against the official docs before building, since GHL updates endpoints periodically.

Key fields to push back:

• Job completion date → custom field in GHL
• Job total revenue → custom field in GHL
• Job type (repair, install, maintenance) → custom field or tag
• Technician name → custom field (useful for review request personalization)
• Business unit → tag in GHL

Step 3: Trigger a Post-Job Automation in HighLevel

This is where the integration pays for itself. Once the contact record is updated:

1. Add one more HTTP module to apply a tag in HighLevel
2. Use POST https://services.leadconnectorhq.com/contacts/{contactId}/tags with Authorization: Bearer {your_GHL_private_api_key} and Version: 2021-07-28 headers to apply a tag like job-completed
3. In HighLevel, build a workflow that triggers on that tag

That workflow can:

• Send a review request via SMS 2 hours after job completion
• Trigger a membership plan upsell email sequence 3 days later
• Add the contact to a seasonal maintenance reminder campaign
• Notify the sales team if the completed job was over a certain dollar threshold

The same double-entry frustration applies when you explore connecting Make.com with Jobber for field service automation.

For a deeper automation layer, exploring whether Make.com integrates with ServiceTitan can unlock even more powerful multi-step workflows for your business.

Many service businesses also wonder about GoHighLevel integrate with Housecall Pro before deciding which field service stack works best for them.

• You get fewer than 10 leads per week. Manual entry takes under 30 minutes. Your time is better spent elsewhere.
• You are not using HighLevel for follow-up automation. If GHL is just a landing page builder, pushing data to ServiceTitan manually takes two minutes and an integration adds unnecessary moving parts.
• Your ServiceTitan API access is restricted. Some legacy plans or franchise accounts have limited API permissions. Confirm access before investing setup time.
• You need sub-second sync. Make.com introduces a small delay (seconds to minutes depending on trigger type). If your dispatch workflow demands instant data, you need a direct custom integration, not a middleware tool.

For contractors scaling without adding admin staff, HighLevel for marketing automation and ServiceTitan for field operations work well together, this integration is the connective tissue.

Electricians especially benefit from pairing these integrations with AI phone answering for electricians to capture leads around the clock.

A similar Make.com integration with Housecall Pro follows the same logic if you serve residential clients instead.

You can also explore the AI front desk ServiceTitan integration to automatically capture after-hours job requests without missing a call.

Here is your action list to build it today:

1. Confirm your ServiceTitan API access. Log into ServiceTitan, go to Settings > Integrations > API, and verify you have an app key and Client ID/Secret. If not, contact ServiceTitan support, activation typically takes 24-48 hours.
2. Create a free Make.com account. Visit Make’s site (check Make’s pricing page for current rates) and sign up. The free tier gives you enough operations to test.
3. Build Workflow 1 (HighLevel to ServiceTitan) using the steps above. Test it with a single real lead.
4. Build Workflow 2 (ServiceTitan to HighLevel) once Workflow 1 is running clean. Start with the job completion tag and a simple review request.
5. Monitor for 7 days. Check Make.com’s execution logs daily. Fix any field mapping issues that surface with real data.

The contractors who win aren’t the ones with the biggest ad budgets. They are the ones whose systems talk to each other without anyone copying and pasting in between.
