Please use the `/provider` endpoint to view available types for each provider. **Availability: Assisted providers only** ## OpenAPI ````yaml post /employer/benefits/register openapi: 3.1.0 info: title: API Reference version: '2020-09-17' contact: {} description: >- The Finch HRIS API provides a unified way to connect to a multitide of HRIS systems. The API requires an access token issued by Finch. By default, Organization and Payroll requests use Finch's [Data Syncs](/developer-resources/Data-Syncs). If a request is made before the initial sync has completed, Finch will request data live from the provider. The latency on live requests may range from seconds to minutes depending on the provider and batch size. For automated integrations, Deductions requests (both read and write) are always made live to the provider. Latencies may range from seconds to minutes depending on the provider and batch size. Employer products are specified by the product parameter, a space-separated list of products that your application requests from an employer authenticating through Finch Connect. Valid product names are— - `company`: Read basic company data - `directory`: Read company directory and organization structure - `individual`: Read individual data, excluding income and employment data - `employment`: Read individual employment and income data - `payment`: Read payroll and contractor related payments by the company - `pay_statement`: Read detailed pay statements for each individual - `benefits`: Create and manage deductions and contributions and enrollment for an employer [![Open in Postman](https://run.pstmn.io/button.svg)](https://god.gw.postman.com/run-collection/21027137-08db0929-883d-4094-a9ce-dbf5a9bee4a4?action=collection%2Ffork&collection-url=entityId%3D21027137-08db0929-883d-4094-a9ce-dbf5a9bee4a4%26entityType%3Dcollection%26workspaceId%3D1edf19bc-e0a8-41e9-ac55-481a4b50790b) servers: - url: https://api.tryfinch.com description: '' security: [] tags: - name: Organization - name: Payroll - name: Deductions - name: Management - name: Sandbox paths: /employer/benefits/register: post: tags: - Deductions summary: Register Deduction description: >- Register existing benefits from the customer on the provider, on Finch's end.
