n-What the ServiceTitan API Actually Lets You Build
ServiceTitan has a documented, OAuth2-based REST API covering jobs, customers, invoices, technicians, and Pricebook data, plus a Marketplace of pre-built connector apps for common needs like accounting and marketing. The API is what makes custom integration possible once a business needs something the Marketplace's fixed feature set doesn't cover. Some workflows still aren't exposed through the API at all; those need a different approach entirely.
What's actually in the ServiceTitan API
The API covers the core objects you'd expect: customers and locations, jobs and job statuses, invoices and payments, technicians, and Pricebook items. Webhooks exist for several of these, so a job getting marked complete or an invoice getting paid can trigger an outside system in near real time instead of waiting for a scheduled export to run.
The Marketplace sits alongside the raw API as ServiceTitan's own directory of pre-built integrations, mostly covering common needs like accounting sync, marketing attribution, and payment processing. It's a solid starting point for standard needs, but it's a fixed set of features someone else built; it doesn't flex to a business's specific rules the way a custom integration against the API does.
Where the API alone doesn't close the gap
Getting API access requires going through ServiceTitan's developer approval process, which adds real lead time before a build can even start; it's not an instant self-serve key the way some platforms offer.
Some bulk, UI-only operations, like repricing thousands of Pricebook line items at once, simply aren't exposed through the API in bulk form. When that happens, the honest answer isn't that it can't be done; it's that it has to be done through headless-browser automation that drives the actual ServiceTitan interface at scale instead of a person clicking through each item by hand.
What we build on top of the ServiceTitan API
Webhook-driven job events instead of nightly exports
A job marked complete fires a webhook that updates your marketing platform, payroll feed, or reporting dashboard within seconds, rather than everything waiting for a batch export that runs once overnight.
Bulk operations the API doesn't expose, done through the UI anyway
When a task like a bulk Pricebook update isn't available through ServiceTitan's API, we build headless-browser automation that performs it directly through the ServiceTitan interface at scale, so the limitation in the API doesn't become a limitation on what actually gets fixed.
What's not connected to ServiceTitan that should be?
Tell us what system needs ServiceTitan's data, or needs to send data into it, and we'll check what the API supports and what would take a different approach.
Hit a wall trying to connect something to ServiceTitan?
Tell us what you're trying to connect and what you've already tried. We'll check whether the API covers it, whether a Marketplace app already does, or whether it needs a custom build through the interface itself. And if ServiceTitan isn't where your real integration gap is, that's fine too, we build connections across whatever tools your business actually runs.
