Factorial (API Key) - How do I link my account?

Overview

To authenticate with Factorial using an API key, you need:

1. API Key - A single token that grants full admin access to your company’s Factorial account and never expires.
2. Environment - Whether to connect to Factorial’s Production or Demo (Sandbox) environment.

This guide will walk you through generating an API key from the Factorial platform.

API keys are not scoped to a user — they grant total access to the entire company account on the platform’s behalf. Only a company administrator should generate one, and it’s their responsibility to store it securely.

Prerequisites

• Admin access to your company’s Factorial account

Instructions

Step 1: Generating your API key

1. Log in to Factorial as an administrator and go to Settings → API Keys.
2. Click New API Key.

3. Enter a name for the key, then click Get My API key.
4. Copy the key that’s shown — it is displayed only once. If you lose it, you’ll need to generate a new one.

Step 2: Choosing your environment

In the Environment dropdown, select api.factorialhr.com for your live Factorial account, or api.eu2.demo.factorial.dev if you’re testing against Factorial’s demo/sandbox environment.

Step 3: Enter credentials in the Connect UI

Once you have your API Key:

1. Open the form where you need to authenticate with Factorial.
2. Enter the API Key in the field provided.
3. Select the Environment you chose in step 2.
4. Submit the form, and you should be successfully authenticated.

You are now connected to Factorial.
