# Pleo - How do I link my account?

# Overview

To authenticate with Pleo, you need:

1. **OAuth Subdomain** - The subdomain used for Pleo's OAuth authorization flow.
2. **API Subdomain** - The subdomain used for Pleo API requests.

This guide will walk you through entering the correct values for your Pleo environment.

### Prerequisites:

* You must have a Pleo account with API access.

### Instructions:

#### Step 1: Identify your environment

Use the following values depending on your Pleo environment:

| Environment | OAuth Subdomain | API Subdomain      |
| ----------- | --------------- | ------------------ |
| Production  | `auth`          | `external`         |
| Staging     | `auth.staging`  | `external.staging` |

#### Step 2: Enter credentials in the Connect UI

1. Open the form where you need to authenticate with Pleo.
2. Enter both **OAuth Subdomain** and **API Subdomain** in their respective fields.
3. Submit the form, and you should be successfully authenticated.
