# Circleback - How do I link my account?

## Overview

To authenticate with Circleback, you need:

1. **API Key** — a personal API key (`cb_<secret>`) created in Circleback settings. Requests made with it read the meetings of the Circleback user who created it.

This guide will walk you through obtaining your API key from Circleback.

### Prerequisites

* A Circleback account with access to the meetings you want to sync. Each person connects their own key; there is no workspace-wide key that reads other users' meetings.

### Step 1: Obtaining your API key

1. Log in to [Circleback](https://circleback.ai) and open **Settings** from the account menu.

2. Select **API keys** in the settings sidebar.

3. Click **Create API key**. Circleback shows the full secret (`cb_...`) once at creation time; the key list only shows masked previews afterwards, and a deleted key cannot be retrieved.

4. Copy the secret somewhere secure until you have pasted it into Nango.

> [!NOTE]
>
> Treat this API key as a password: never put it in source code, URLs, logs, or client-side applications. Nango stores it encrypted and only uses it server-side to call the Circleback API on your behalf.

### Step 2: Enter your API key in the Connect UI

Once you have your API key:

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

You are now connected to Circleback.
