Support add_contractors in company flows

Gusto Embedded now support add_contractors as a flow param for the POST /v1/companies/{company_uuid}/flows endpoint. This will allow users to create new contractors for a company.

Add has_ein field in GET contractor

Added a new field has_ein in GET all contractors and GET a single contractor APIs to determine if the contractor has an employer identification number or not.

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.
