Jentic publishes the only available OpenAPI specification for Gusto App Integrations API, keeping it validated and agent-ready. The Gusto App Integrations API is the partner-facing surface used by HR, time-tracking, expense, and benefits apps to read and write company, employee, payroll, and benefits data inside Gusto. Its 100 endpoints span companies, locations, departments, employees, jobs and compensations, employee employments, addresses, time-off policies, custom fields, contractors, company benefits, employee benefits, pay schedules, and webhooks. Authentication uses OAuth 2.0 access tokens issued at the company or system scope.
100 endpointsJentic publishes the only available OpenAPI specification for Gusto Embedded Payroll API, keeping it validated and agent-ready. Gusto Embedded Payroll is the white-label payroll platform partners use to run US payroll inside their own product. Its 213 endpoints cover partner-managed company creation and migration, federal and state tax details, employees and contractors, jobs and compensations, payroll runs, off-cycle and historical payrolls, garnishments, time-off policies, holiday pay, employee benefits, signatories, and onboarding flows. Authentication uses partner-scoped tokens via Authorization bearer or API key header.
213 endpointsStep 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fgusto-demo.com" | shStep 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fgusto-demo.com" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
