// SERVICETITAN + GOHIGHLEVEL

ServiceTitan integrations: what is allowed, and GoHighLevel

ServiceTitan integrations are the approved ways other software connects to ServiceTitan: certified Marketplace apps, apps a customer builds for itself, and ServiceTitan's Zapier app. We are not a ServiceTitan partner. We set up GoHighLevel lead handling and connect it through your own ServiceTitan Zapier connection. Web Blend runs GoHighLevel in-house.

// HOW SERVICETITAN API ACCESS WORKS

The ServiceTitan integration paths, and the one that is banned

ServiceTitan controls API access more tightly than most job systems. This summary comes from its developer portal, help center and API terms, checked 15 September 2026.

PathWho builds and owns itWhen it fits
Certified App (Marketplace)A ServiceTitan partner that has completed certification and a partnership agreementBuying an off-the-shelf product that already connects, such as the apps in the Leads and Bookings or Marketing categories.
Customer-Built AppYour own business: you request access, build, host and maintain it with your own App KeyBusinesses with an in-house developer. Needs the Works or Enterprise Plus package.
ServiceTitan Zapier appYour admin registers and connects it; zaps run in a Zapier account you ownLighter connections, including GoHighLevel through LeadConnector. ServiceTitan says it is not officially supported.
Tunneling (not allowed)A third party asks you to create an app and share the App Key, or you give them app-creation rightsNothing. ServiceTitan prohibits it and may ask you to disconnect it. We will not ask you to do this.

Customer-built apps use an App Key, a Client ID and Client Secret per environment, and your Tenant ID, with requests capped at 60 calls per second per app per tenant. Your admin approves each app under Settings, Integrations, API Application Access.

// THE SERVICETITAN MARKETPLACE

Native ServiceTitan integrations by category

Check marketplace.servicetitan.com first. ServiceTitan relaunched it in September 2025 around certified apps, and says apps that do not certify are removed and treated as custom integrations. Categories include:

A search for HighLevel, LeadConnector and Zapier on the Marketplace returned no results when checked.

// WHAT MOVES WHICH WAY

What a ServiceTitan GoHighLevel connection syncs

The shape of a build through ServiceTitan's Zapier connection. Exactly trigger and action names are from ServiceTitan's Zapier app listing, and you sign off the field map before anything is wired.

GoHighLevel → ServiceTitan

The inquiry becomes a booking

  • A GoHighLevel inquiry uses the ServiceTitan ZapierCreate Booking action, so it lands on the Calls screen for your CSRs to accept or dismiss, rather than a job nobody reviewed.
  • The booking carries the name plus phone, email or address ServiceTitan requires, with the form answers and lead source included.
  • Your CSRs keep control of booking, so dispatch, capacity and arrival windows stay inside ServiceTitan.
ServiceTitan → GoHighLevel

Job reality reaches follow-up

  • The ServiceTitan ZapierNew Job trigger updates the matching GoHighLevel opportunity, so follow-up stops chasing a customer who is already booked.
  • Updated Job and Updated Estimate triggers move the pipeline and start or stop estimate follow-up in GoHighLevel.
  • Inquiries that never become jobs stay in GoHighLevel nurture instead of disappearing.

When you do not need us

This is worth doing when your ads and web leads live in GoHighLevel and your CSRs retype them into ServiceTitan. It is not worth doing in these cases.

Skip it if
  • A certified app in the ServiceTitan Marketplace already does what you need. Buy that; it is the supported route.
  • Your team runs follow-up inside ServiceTitan's own marketing tools and you have no plans to run GoHighLevel.
  • Your ServiceTitan package does not include API or Zapier access. None of the routes on this page work until that changes.
  • You want a direct API integration built on your App Key by an outside agency. ServiceTitan calls that Tunneling and does not allow it.

// HOW IT RUNS

Four steps, with your credentials staying yours

01

Confirm your package and route

We check which ServiceTitan package you are on and whether a certified app, your own app, or the Zapier connection fits. If a Marketplace app covers it, we say so.

02

Your admin connects ServiceTitan

Your admin completes ServiceTitan's Zapier registration and approves it under API Application Access. You own the credentials. We never ask for your App Key.

03

We build the GoHighLevel side

Pipelines, lead capture, missed-call text-back and follow-up workflows in GoHighLevel, connected to ServiceTitan bookings and job updates.

04

Test, hand over, support

Tested on non-customer records, documented in plain English, with a written agreement on who fixes what when either platform changes.

// PRICING

From $1,284, one fixed number before we start

Connecting ServiceTitan to GoHighLevel starts from $1,284 setup as part of our automation service. That covers the GoHighLevel build and the Zapier connection to your account. ServiceTitan, GoHighLevel and Zapier subscriptions are separate. No hourly billing and no lock-in contract.

Running Jobber or Housecall Pro instead? See Jobber integrations or Housecall Pro integrations. If missed calls are the bigger leak, start with missed-call text-back.

// QUESTIONS

ServiceTitan integration questions

Get in touch
Does ServiceTitan integrate with GoHighLevel?

Not through a listed Marketplace app. A search of the ServiceTitan Marketplace for HighLevel and LeadConnector returned no results in September 2026. Zapier lists a ServiceTitan and LeadConnector pairing, and HighLevel's help center documents connecting the two through Zapier. That route needs a ServiceTitan package with Zapier access.

Can an agency build a ServiceTitan API integration for me?

Not on your credentials. ServiceTitan approves two paths: Certified Apps from partners, and apps a customer builds, hosts and maintains itself. It prohibits Tunneling, which is when a third party asks you to create an app and share its App Key, or is given permission to create apps. Web Blend is not a ServiceTitan partner, so we do not offer a direct API build.

Which ServiceTitan package includes API access?

ServiceTitan's developer portal says customer-built apps need the Works or Enterprise Plus package. Its help article on Zapier says that connection is for The Works or legacy customers. Check your package with ServiceTitan before planning an integration.

What is a ServiceTitan booking?

A booking is an inquiry sent into ServiceTitan that appears on the Calls screen, where your team accepts or dismisses it. It needs a name plus an address, phone number or email. It suits web and ad leads, because a person still decides whether it becomes a job.

Is the ServiceTitan Zapier connection reliable?

It works, with caveats you should know. ServiceTitan's help center describes its Zapier app as not officially supported and provided as is, and ServiceTitan's API terms say API usage may carry fees in the future. We build failure alerts into the zaps and tell you plainly what depends on it.

How much does it cost to connect ServiceTitan to GoHighLevel?

Setup starts from $1,284 inside our automation service, for the GoHighLevel build and the Zapier connection to your ServiceTitan account. Zapier and ServiceTitan subscriptions are separate. You get one fixed price before work starts, no hourly billing and no lock-in contract.
