API infrastructure

Before you start using our API dev portal, understand how it works, including how it validates key pairs, returns access tokens, and how to make a successful call.

Our V2 APIs offer a range of endpoints for features like Jobs, Projects, Invoices, Payroll, Pricebook, and more. We follow OAuth2.0 protocol and machine-to-machine grant flow.

A successful V2 API call looks like this:

  1. Call OAuth 2.0 API, Pass Client ID and Secret Key. ServiceTitan validates the key pair and returns an access token.

  2. Call individual API & Pass Access Token and App Key. ServiceTitan validates credentials and processes the API call.

For more information, see Make your first API call.
