[n8n](https://n8n.io) is a fair-code, extendable workflow automation tool. You can connect Reloop to your n8n workflows using either:

1. **SMTP Connection** (using n8n's built-in **Send Email** node)
2. **REST API Connection** (using n8n's built-in **HTTP Request** node)

---

## Method 1: SMTP via n8n's Send Email Node

You can route emails directly using n8n's native **Send Email** node configured with Reloop's SMTP credentials.

### Step 1: Add the Send Email Node
1. Inside your n8n workflow editor, click the **+** icon to add a node.
2. Search for and select the **Send Email** node.

### Step 2: Configure Credentials
1. Under **Credential for Send Email**, select **Create New Credential**.
2. Set the connection settings as follows:

| Parameter | Value |
| :--- | :--- |
| **Host** | `smtp.reloop.sh` |
| **Port** | `587` |
| **SSL/TLS** | `STARTTLS` (enabled via toggle / selection) |
| **User** | *Your Reloop API Key* (starts with `rl_`) |
| **Password** | *Your Reloop API Key* (starts with `rl_`) |

3. Save the credential.

### Step 3: Set Email Parameters
Configure the email body and headers:
- **From Email**: Enter a verified email address from your Reloop sending domain (e.g., `app@yourdomain.com`).
- **To Email**: Map the recipient's email address dynamically from prior nodes.
- **Subject**: Enter a subject line.
- **HTML / Text**: Choose your email body format and insert your content.

## Method 2: REST API via HTTP Request Node

Use n8n's **HTTP Request** node to access advanced API features such as templating, tag tracking, attachments, or scheduling.

### Step 1: Add the HTTP Request Node
1. Click the **+** icon to add a new node.
2. Search for and select **HTTP Request**.

### Step 2: Configure Node Parameters
Configure the node parameters for the Reloop Send Mail API:

- **Method**: `POST`
- **URL**: `https://reloop.sh/api/mail/v1/send`
- **Authentication**: `Header Auth` (or choose None and add it manually in Headers)
- **Headers**:
  - Name: `x-api-key`
  - Value: *Your Reloop API Key*
  - Name: `Content-Type`
  - Value: `application/json`
- **Specify Body**: `Using JSON`
- **Body Parameters**: Toggle to **JSON** format and enter the payload:
```json
{
  "from": "Marketing <marketing@yourdomain.com>",
  "to": "={{ $json.email }}",
  "subject": "Thank you for subscribing!",
  "html": "<h1>Welcome {{ $json.name }}!</h1><p>We are glad to have you aboard.</p>",
  "tags": [
    {
      "name": "campaign",
      "value": "onboarding_n8n"
    }
  ]
}
```
*Note: Use n8n's expression syntax `={{ ... }}` to pull data from your webhook or database triggers.*

---

## Step 3: Test and Verify
1. Click **Test step** or **Execute Node** in n8n.
2. Inspect the JSON response to ensure it returns a success confirmation:
```json
{
  "success": true,
  "messageId": "msg_8d8b9c2a1e...",
  "status": "sent"
}
```
3. Check your recipient inbox and check the **Reloop Dashboard Logs** to confirm the email was delivered successfully.
