How do I automate Gusto Embedded Payroll company onboarding via API?

Gusto Embedded Payroll onboarding is automated by creating companies, completing onboarding steps, and configuring tax and bank details via API. It manages the full company lifecycle without manual workflow steps.

How do I handle Gusto API OAuth 2.0 refresh-token rotation for payroll integrations?

Gusto API OAuth 2.0 refresh-token rotation is managed using the authorization-code flow with rotating refresh tokens. Correct rotation ensures continuous access for automated payroll runs and payroll-history reads.

What is the best way to verify Gusto webhook payloads for contractor payments?

Gusto webhook payloads are verified using HMAC verification for payload integrity. This ensures that incoming webhook events for contractor payments and payroll execution are authentic and unaltered.

Do I need a human-approval step to submit payrolls via the Gusto Embedded Payroll API?

A human-approval step is required to submit payrolls via the Gusto Embedded Payroll API. The system uses guarded write flows to separate automated read operations from human-gated payroll submissions.

Can I manage employee compensation and terminations using the Gusto Partner API?

The Gusto Partner API supports managing employee and contractor onboarding, handling jobs and compensation, and processing terminations. It also facilitates drafting contractor payments within sandbox and production workflows.

Why are pinned X-Gusto-API-Version headers required for Gusto Embedded Payroll syncs?

Pinned X-Gusto-API-Version headers are required for Gusto Embedded Payroll syncs to ensure versioned requests behave predictably. This prevents breaking changes when running pay schedules or fetching payroll history for dashboards.
