Added new param contractor_uuid to GET contractor payments endpoint

Added contractor_uuid as an optional param for the GET contractor_payments endpoint.
When specified, queries for all contractor payments for that specific contractor.

Added External Payroll Flow to Company Flows Endpoint

We added external_payroll as a flow param for the post-v1-company-flows endpoint. This will allow users to create and access the new External Payrolls flow. This flow is used for creating external payroll records when a company transfers from another payroll provider after the start of the year.

External payroll item tax calculation API

We introduced a payroll item tax calculation API. Earnings and/or benefits data must be saved prior to the calculation in order to retrieve accurate tax calculation.

External payrolls

We have launched external payroll APIs to support customers who transfer from one payroll provider to Gusto payroll provider. These APIs collect their employees’ payrolls and tax information so that we can properly file them at the end of the year.

New Flag Added to Identify a Company Status

The boolean is_partner_managed was added to the Companies API to identify if a company is fully managed by a partner via the API or a Gusto customer that has get to migrate over.

$ UI Helper Added to Amount Fields in Flows

A $ sign helper was added to the left of any amount fields in pre-built Flows for onboarding and run payroll.

Run Payroll Flow

Gusto shipped a Run Payroll Flow to offer a faster way to build embedded payroll. This Run Payroll Flow is embeddable pre-built UI that can be used to accelerate your time to market and save your team weeks of engineering resources!

Off-cycle reason now included in payroll response

The off_cycle_reason string is now returned as part of the payrolls response (correction or bonus).
