Most contractors assume connecting ServiceTitan to outside tools requires a developer. For straightforward lead-push tasks, that’s not true. A non-technical business owner can bridge Make.com and ServiceTitan using Make’s HTTP module and ServiceTitan’s documented API — no code written. Setup takes one afternoon once ServiceTitan approves your API access.
The math: Time to implement: ~45 min active work | Tasks automated: lead entry from calls/forms | Weekly time reclaimed: ~2-4 hours
- Make.com has no native ServiceTitan module but HTTP works.
- AI Front Desk captures after-hours calls that trigger the bridge.
- Active setup takes under 60 minutes once API access is granted.
The Short Answer: No Native Module (But You Can Build a Bridge)
There is no drag-and-drop ServiceTitan module in Make.com’s app library. There is, however, a working alternative.
ServiceTitan is a field service management platform built for home service companies: dispatch, scheduling, invoicing, customer records. Make.com is a visual automation platform where you build “scenarios” (automated workflows) without writing code.
ServiceTitan keeps tighter API controls than platforms like Housecall Pro or Jobber. Their reasoning: enterprise clients need data security controls that a pre-built connector might not satisfy. This means API access is permissioned — not every account has it enabled by default, and approval requirements vary by plan. Before assuming you can start building this weekend, contact your ServiceTitan account rep or check under Integrations settings to confirm your account tier includes API access.
Make’s HTTP module is a universal connector. Think of it as a translator: you give it the address (ServiceTitan’s API endpoint), the credentials (your Tenant ID and API key), and the payload (the lead’s name and phone). Make handles the rest.
Some Make users report successfully building these bridges using the HTTP module. The pattern is documented in Make’s HTTP module reference. You just need the right steps — and confirmed API access.
Fixing the ‘After-Hours Voicemail’ Leak With This Setup
The upshot: every missed after-hours call that goes to voicemail is a lead your competitor gets instead.
The scenario that makes this bridge worth building: A homeowner’s water heater bursts at 11 PM. They call three plumbers. Two go to voicemail. One has an AI answering service that picks up, captures their name, phone number, and problem description, then pushes that lead directly into ServiceTitan’s booking queue before the homeowner finishes drying the floor.
That third plumber gets the job. Not because of better skills. Because they answered.
AI Front Desk is an AI voice agent that answers calls 24/7. It qualifies leads using your custom screening questions, then fires a webhook (an automatic data delivery to a URL you specify) containing the caller’s details. The Make.com bridge catches that webhook and formats the data into a ServiceTitan API call.
For owners who prefer live humans on sensitive calls, Ruby Receptionists is worth considering. If your receptionist service can send webhooks — either directly or through a connector like Zapier or Make — the same bridge works. Ruby uses tiered pricing based on receptionist minutes; contact them for current rates. The choice comes down to call complexity: routine lead capture favors AI Front Desk on cost; high-stakes calls where tone closes the deal favor Ruby.
AI Front Desk starts at $79/month on the annual plan, which includes 200 minutes. The Pro plan runs $149/month (billed annually) for higher call volumes.

Take the Quiz →Prerequisites
Before you start, confirm you have:
- A ServiceTitan account with API access enabled — this is permissioned and not available on all plans. Contact your account rep or check under Integrations settings to confirm and request access before starting.
- Your ServiceTitan Tenant ID (a number identifying your company inside their system)
- A ServiceTitan API Application Key and Client Secret (generated in their developer portal)
- A Make.com account (free tier with 1,000 credits/month works for testing)
- A webhook source: AI Front Desk, Ruby, a web form, or any tool that can send data to a URL
Step 1: Get Your ServiceTitan API Credentials (10 minutes active, 1-3 days wait)
Log into ServiceTitan and navigate to the integrations or developer settings area (exact path varies by account type and permissions). Create a new API application. ServiceTitan will generate a Client ID and Client Secret.
Write down three things: your Tenant ID (visible in your account URL or settings), the Client ID, and the Client Secret. Store these somewhere secure. You will paste them into Make.com in Step 3.
Why this matters: These credentials are your handshake. Without them, ServiceTitan’s API rejects every request. This is the security gate that protects your customer data.
Once all three values are written down and your API application shows “Active” status in ServiceTitan’s developer portal, you are ready for Step 2.
Step 2: Create a Make.com Scenario With a Webhook Trigger (5 minutes)
Inside Make.com, create a new scenario. For your first module (the trigger), choose “Webhooks” and then “Custom webhook.” Make will generate a unique URL (see the Make.com documentation). Copy this URL.
This URL is the address your answering service sends lead data to. Paste it into AI Front Desk’s webhook settings, Ruby’s integration panel, or whatever tool captures your inbound calls.
Test the connection by triggering a sample call or manually sending test data. Make.com should show the incoming data structure (name, phone, description fields).
Check that Make.com displays sample data from your test in the webhook module’s output panel, that confirms the connection is live.
Add two more modules to your scenario so the final structure is:
Webhook trigger → HTTP: Get OAuth token → HTTP: Create record in ServiceTitan
Module 2. Get OAuth token: Add an HTTP “Make a request” module. Point it at ServiceTitan’s authentication endpoint. Pass your Client ID and Client Secret in the request body. ServiceTitan returns a temporary access token. Wire that token into Module 3’s Authorization header.
Module 3. Create record: Add a second HTTP “Make a request” module. Configure it with these settings:
Pairing this automation with AI for HVAC scheduling can further reduce manual dispatch work across your service operations.
Your electricians in the field will also appreciate having an AI answering service for electricians handling calls while their hands are occupied.
- URL: The specific ServiceTitan API endpoint for the record type you want to create (customer, job, or appointment, check the ServiceTitan API reference for your account’s available endpoints and exact URL format)
- Method: POST (this means “create new data”)
- Headers: Authorization token from Module 2
- Body type: JSON
- Body content: Map the fields from Step 2’s webhook output (caller name, phone number, description) to ServiceTitan’s required fields for that endpoint
Request a fresh token at the start of every scenario run. This is the simplest reliable pattern for non-developers and avoids expired-token errors.
When both HTTP modules show a green checkmark after a test run, Step 3 is complete.
Step 4: Test With Real Data and Activate (10 minutes)
Run the scenario once manually. Call your own business number (or have a friend call) so your answering service captures a real lead and fires the webhook.
Watch Make.com process the data through both modules. Then open ServiceTitan and check your leads or customer list. The test caller’s name and phone should appear.
If it does not appear: check that your Tenant ID matches, your token has not expired, and the field names in your JSON body match ServiceTitan’s API documentation exactly (capitalization matters).
Many service businesses also explore connecting Make.com with Jobber integration before deciding which field service platform fits their workflow best.
Many contractors using this same API setup also leverage AI to book jobs automatically, removing manual scheduling from their workflow entirely.
Your automation setup pairs well with exploring how AI lead generation for HVAC businesses can keep your pipeline consistently full.
Once confirmed, set the scenario to “On” and choose immediate processing for leads. Make’s free tier includes 1,000 operations per month. Each module execution counts as one operation, so a 3-module scenario like this uses roughly 3 operations per lead processed. That covers around 300 new leads per month on the free tier before you need a paid plan.
Common Pitfalls (and How to Avoid Them)
| Problem | Cause | Fix |
|---|---|---|
| 401 Unauthorized error | Missing or expired access token | Add an HTTP module at the start of your scenario that requests a fresh OAuth2 token on every run. Pass that token as the Authorization header in your lead-creation module. |
| Duplicate contacts in ServiceTitan | Webhook fires multiple times for the same caller | Add a filter module that checks whether the phone number already exists before creating a new record. |
| Fields appear blank in ServiceTitan | JSON key capitalization mismatch | Match ServiceTitan’s exact field casing (e.g., phoneNumber not phonenumber). |
| Scenario stops running | Scenario toggled off, operations limit reached, or auth failure | Check that the scenario is set to On, review your Make.com operations usage, check the scenario error log, and confirm your token request step is succeeding. |
Pro tip: Add a third module—a Slack or email notification—so your team gets pinged the instant a new lead hits ServiceTitan. This closes the loop between “captured” and “someone actually calls them back.”
Before committing to this integration setup, understanding the ServiceTitan vs Housecall Pro AI capabilities can help confirm you’re building on the right platform.
When to DIY vs. When to Call for Backup
This four-step setup is manageable if you are comfortable copying and pasting API keys, reading basic documentation, and troubleshooting error codes. Budget roughly 60–90 minutes for your first working scenario.
Hire help if you need bi-directional sync (ServiceTitan pushing data back to Make.com requires additional server configuration), complex conditional routing (e.g., residential leads to one team, commercial to another), or if your lead source does not support outbound webhooks at all and you need to bridge that gap first.
One Tool, One Hour: Your Next 30 Minutes
You have the blueprint. Here is how to start right now:
- Minute 0–5: Log into ServiceTitan’s developer portal and request API access (the approval clock starts ticking immediately, so do this first).
- Minute 5–15: Create your free Make.com account and explore the HTTP module interface so it looks familiar when your credentials arrive.
- Minute 15–30: Confirm your answering service (or lead source) can fire outbound webhooks. If not, contact their support team today—this is often the longest dependency.
By the time your ServiceTitan API credentials are approved in 1–3 business days, you will be ready to wire everything together in under 30 minutes. No more Monday-morning voicemail triage. Every after-hours lead lands directly in ServiceTitan, tagged, timestamped, and ready for dispatch.

Can I set up a Make.com and ServiceTitan bridge without knowing how to code?
Yes. Make’s visual workflow builder lets you construct the integration by copying credentials and mapping fields, no code written. The main step you cannot skip: requesting API access through your ServiceTitan account rep, which typically takes 1-3 business days for approval. Once your credentials arrive, the active build time is 30-60 minutes.
How much does AI Front Desk cost for a small HVAC business?
AI Front Desk starts at $79 per month (as of May 2026) on the annual plan, which covers 200 minutes of AI receptionist time. That is the Starter tier. Higher call volumes require the Pro plan ($149/month billed annually) or the Enterprise tier, which is contact-vendor pricing. For most small HVAC operations handling after-hours lead capture, the $79/month annual plan is the starting point.
What happens if the AI makes a mistake on a customer call?
AI Front Desk can flag conversations for human review or route callers to a live agent when it cannot confidently capture key details. The system is configured to prioritize name and phone number accuracy above all else. Any gaps get filled by your team when they open the lead in ServiceTitan, the record is already there, timestamped, so nothing falls through completely.
How long before I see results from automating my lead intake?
You can expect to see a reduction in manual data entry within the first week of your automation being active. The primary result is reclaiming 2-4 hours per week previously spent on double-entry, starting from the moment your first automated lead flows from a source like a website form into ServiceTitan.
