# Agile CRM - How do I link my account?

## Overview

To authenticate with Agile CRM, you need:

1. **Agile CRM Domain** — the domain of your Agile CRM account.
2. **Email** — the email address you sign in to Agile CRM with.
3. **REST API Key** — the API key Agile CRM uses for REST API calls.

This guide will show you where to find each of them.

### Prerequisites

* An Agile CRM account. [Sign up](https://www.agilecrm.com/signup) for free, no credit card required. The free plan allows 500 API calls per day.

### Step 1: Find your Agile CRM domain

Your domain is the name you chose at signup. It is the part of your Agile CRM URL before `.agilecrm.com`: for `https://acme.agilecrm.com`, enter `acme`.

### Step 2: Copy your REST API key

1. Sign in to your Agile CRM account with the email address you will enter in the **Email** field.
2. Open **Admin Settings**, then go to **API & Analytics**.
3. Copy the first key, **API Key** (for REST client). Agile CRM uses this key for all REST API calls.

### Step 3: Enter your credentials in the Connect UI

1. Open the form where you need to authenticate with Agile CRM.
2. In **Agile CRM Domain**, enter your domain from Step 1 (for example, `acme`).
3. In **Email**, enter the email address you sign in to Agile CRM with.
4. In **REST API Key**, paste the API key from Step 2.
5. Submit the form. Nango checks the credentials with Agile CRM before saving the connection.
