# AgentLine - How do I link my account?

# Overview

To authenticate with AgentLine, you need an **API key** — a Bearer token that grants access to your AgentLine account (phone numbers, calls, and SMS).

This guide will walk you through finding your API key within AgentLine and connecting it to Nango.

### Prerequisites:

* You must have an **AgentLine account**. Sign up at [agentline.cloud](https://agentline.cloud).

#### Step 1: Finding your API key

1. Sign up or log in at [agentline.cloud](https://agentline.cloud).
2. Go to your dashboard and copy your API key (starts with `al_live_`).

<Tip>Keep your API key secret — it grants full access to your AgentLine account.</Tip>

#### Step 2: Enter your API key in Nango

Once you have your **API key**:

1. Open the form where you need to authenticate with AgentLine.
2. Enter the **API key** in the designated field.
3. Submit the form, and you should be successfully authenticated.
