# N8N

**n8n** is a source-available workflow automation platform that lets you connect Clearout with hundreds of apps and services through a visual, node-based editor — no coding required. You can self-host it or use n8n Cloud to automate tasks such as email verification and email discovery whenever data flows between your forms, CRMs, spreadsheets, and other tools.

## What Clearout Can Do in n8n

Clearout works with n8n to provide you powerful email-related actions that you can use in your workflows. The two main actions you can do are

### **Verify Email Address**

Validate an email address in real-time to determine its deliverability and quality. Clearout checks syntax, domain validity, mailbox existence, and risk factors to help you filter out invalid or unsafe emails before sending.

### **Find Email Address**

Discover a professional email address in real-time using a person’s name and company domain. Clearout identifies the most likely email pattern and returns pre-verified, deliverable results for outreach.

These actions help you keep your data accurate and make outreach easier.

## Prerequisites

* **Clearout API Token** - Log in to your Clearout account and go to [**Developer → API**](https://app.clearout.io/developer/api/list) to create or copy your API token.
* **n8n Instance** - Ensure you have access to your n8n workspace (Cloud or self-hosted).

## Setup Clearout on n8n

{% step %}

### Add the HTTP Request Node <a href="#add-http-node" id="add-http-node"></a>

In your n8n workflow, click the **+** icon and add an **HTTP Request** node at the point where you want the email verification or email finding to occur.

<div data-with-frame="true"><figure><img src="/files/24cexutuYMT1GErZSe0W" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}

### Configure Authentication <a href="#configure-auth" id="configure-auth"></a>

To authenticate your requests, set a header on the HTTP Request node:

* **Header Name:** `Authorization`
* **Header Value:** `Bearer <YOUR_API_KEY>`

Follow these steps inside the node:

1. Set **Authentication** to **Generic Credential Type**.

<div data-with-frame="true"><figure><img src="/files/ZPsvUfozS7BibIYa4ET1" alt=""><figcaption></figcaption></figure></div>

2. Set **Generic Auth Type** to **Header Auth**.

<div data-with-frame="true"><figure><img src="/files/zRyKo1ycpZkczZqBZQ1a" alt=""><figcaption></figcaption></figure></div>

3. Click **Create New Credential** to set up credentials.

<div data-with-frame="true"><figure><img src="/files/TpZMn24utzcBUlwgabaT" alt=""><figcaption></figcaption></figure></div>

4. In the credential popup:

* Fill the **Name** field as `Authorization`.
* Fill the **Value** field as `Bearer <YOUR_API_KEY>` (replace `<YOUR_API_KEY>` with the token from the prerequisites).

<div data-with-frame="true"><figure><img src="/files/TCQgzARKY5sfO87xGvJ7" alt=""><figcaption></figcaption></figure></div>

5. Click **Save**.
   {% endstep %}

{% step %}

### Set Request Parameters <a href="#set-parameters" id="set-parameters"></a>

Configure the node with the following settings:

| Parameter                                                                                                      | Value                                               |
| -------------------------------------------------------------------------------------------------------------- | --------------------------------------------------- |
| **Method**                                                                                                     | POST                                                |
| **URL** ([Email Verification](https://docs.clearout.io/developers/api/email-verify#post-email_verify-instant)) | <https://api.clearout.io/v2/email\\_verify/instant> |
| **URL** ([Email Finder](https://docs.clearout.io/developers/api/email-finder#post-email_finder-instant))       | <https://api.clearout.io/v2/email\\_finder/instant> |
| **Send Body**                                                                                                  | True                                                |
| **Body Content Type**                                                                                          | `JSON`                                              |

<div data-with-frame="true"><figure><img src="/files/tomWe7lPWAILDlrhi6Rb" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}

### Define the Payload <a href="#define-payload" id="define-payload"></a>

Pass the **name** and **domain** (or company name) in the body of the request — not as query parameters. Use n8n expressions to dynamically map values from previous nodes.

{% code title="Email Verification Payload " %}

```json
{
  "email": "valid@example.com",
  "timeout": 10000
}
```

{% endcode %}

{% code title="Email finder Payload" %}

```json
{
  "name": "Steven Morris",
  "domain": "apple.com",
  "timeout": 30000,
  "queue": false
}
```

{% endcode %}

<div data-with-frame="true"><figure><img src="/files/dP0xISOzLGGRumPGa0OA" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}

### Handle the Response <a href="#handle-response" id="handle-response"></a>

Once the node is executed, the results will appear in the **Output** section. For email finding, the response typically includes the discovered email address along with a confidence score. For email verification, it includes the verification status (`Valid`, `Invalid`, `Catch-all`, etc.) and a confidence score.

<div data-with-frame="true"><figure><img src="/files/G72LZNZdloQZ4ROrW9rO" alt=""><figcaption><p>Clearout Email Finder Response</p></figcaption></figure></div>

From here, you can add more nodes (filters, CRM updates, Google Sheets writes, notifications) to route the data based on your workflow logic and fully **automate your process with Clearout and n8n.**
{% endstep %}
{% endstepper %}

Clearout provides webhook support to efficiently handle long-running processes without requiring continuous polling. Instead of waiting for a synchronous response, you can configure a [webhook](https://app.clearout.io/developer/webhook) URL where Clearout will send the results once processing is complete.
