This API Quickstart guide will help you send your first request to Finch, the unified API for HR and payroll.

Quickstart

The Finch API powers integrations to employment systems through a single, standardized data model.

What is Finch?

Finch Connect is an embedded onboarding flow that enables employers to connect their HR or payroll system to your app.

Connect an Employer

Use this glossary to familiarize yourself with employment terminology used in Finch's documentation and API reference.

 In a full implementation, Finch requires both a frontend and a backend application to exist. The frontend application coordinates connecting the employer's system, and the backend server securely manages the requests and responses to and from Finch APIs.  <br /> <br /> Use this Implementation Guide and Go Live Checklist to set up your frontend and backend applications. You will sign up for a Finch Account, set up Finch Connect, integrate the Finch API, and go into production.

Go Live Checklist

Create your Finch Developer Account, recieve your application credentials, and pilot how Finch works in our sandbox environment.

Create a Finch Developer Account

Before being able to pull data from an employment provider through Finch, your customer needs to consent to the data being transferred. Without consent, Finch is not authorized to pull the data on behalf of the customer. Finch Connect is our user-facing product to help you obtain customer consent, and it is a prerequisite step before calling Finch APIs. 

Integrate Finch Connect Into Your Application

In this guide, you’ll exchange the authorization code for an access token. Access tokens are required for making API requests to Finch endpoints.

Retrieve Access Token

In this guide, you'll build a robust testing, validation, and maintenance plan for your Finch API integration to improve reliability, accuracy, and performance.

Develop Your Test Plan

Use Provider Sandboxes to test up to 5 connections with live providers for free. Test with Gusto, Deel, Hibob, BambooHR, TriNet HR Platform (fka Zenefits), and more.

Provider Sandboxes

Use the Finch Sandbox to generate mock connections with Finch providers, see which fields are supported, and configure the data for unique testing scenarios.

Finch Sandbox

Finch takes security seriously, so we require a backend server to manage all requests and responses to and from Finch APIs. Once the connection has been created via Finch Connect, you can obtain an `access_token` which will be used to call the Finch APIs. We offer several [backend SDKs](/developer-resources/SDKs#backend-sdks) to make the backend integration smoother.

Backend Security

***Finch requires developers to store tokens on the backend server for improved security controls***. To reduce the likelihood of unitentional exposure of employer access tokens or other private information, you'll need to ensure all access tokens are stored securely.

Store Tokens

Learn how Finch defines connections, and how to safely disconnect all access tokens associated with a connection if needed.

Disconnect Tokens

In this guide, you'll learn how to identify and mitigate common errors such as server errors, reauthentication errors, and rate limit errors.

Mitigate Errors

In this guide, you'll find best practices for monitoring your application's usage of Finch to identify patterns and potential issues.

Monitor Usage

Learn how to control data access within multi-tenancy applications through role-based access control (RBAC) or other authorization methods.

Control Access (Optional)

In this guide, you'll learn how to define and manage multi-account, multi-provider, and multi-entity connections based on your customers' needs.

Manage Connections

In this guide, you'll learn how to read data from Finch's company, directory, individual, employment, payment, and pay statement API endpoints.

The Forward API allows you to make direct requests to an employment system. If Finch’s unified API
doesn’t have a data model that cleanly fits your needs, then Forward allows you to push or pull
data models directly against an integration’s API.

Get all automated jobs. Automated jobs are completed by a machine. By default, jobs are sorted in descending order by submission time. For scheduled jobs such as data syncs, only the next scheduled job is shown.

List All Automated Jobs

Enqueue an automated job. Currently, only the `data_sync_all` job type is supported, which will enqueue a job to re-sync all data for a connection. `data_sync_all` has a concurrency limit of 1 job at a time per connection. This means that if this endpoint is called while a job is already in progress for this connection, Finch will return the `job_id` of the job that is currently in progress. Finch allows a fixed window rate limit of 1 forced refresh per hour per connection.

This endpoint is available for *Scale* tier customers as an add-on. To request access to this endpoint, please contact your Finch account manager.
