# Create Tag

> Create a new email account tag with a name and optional color

<Note>
  Create tags to organize your email accounts into groups for easy filtering and management. Each tag can have a custom color for visual identification.
</Note>

## Overview

Creates a new tag that can be assigned to email accounts. Unlike the [Update Tag](/api-reference/email-account-tags/create) endpoint, this does not require an existing tag ID — the system generates one automatically.

## Query Parameters

<ParamField query="api_key" type="string" required>
  Your SmartLead API key
</ParamField>

## Request Body

<ParamField body="name" type="string" required>
  Display name for the tag
</ParamField>

<ParamField body="color" type="string">
  Hex color code for the tag (e.g., `#FF5733`). Must be a valid 6-character hex color with `#` prefix. If not provided, a default color will be assigned.
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl -X POST "https://server.smartlead.ai/api/v1/tags?api_key=YOUR_KEY" \
    -H "Content-Type: application/json" \
    -d '{"name": "Primary Senders", "color": "#4CAF50"}'
  ```

  ```python Python theme={null}
  import requests

  API_KEY = "YOUR_API_KEY"

  response = requests.post(
      "https://server.smartlead.ai/api/v1/tags",
      params={"api_key": API_KEY},
      json={
          "name": "Primary Senders",
          "color": "#4CAF50"
      }
  )

  result = response.json()
  print(result)
  ```

  ```javascript JavaScript theme={null}
  const API_KEY = 'YOUR_API_KEY';

  const response = await fetch(
    `https://server.smartlead.ai/api/v1/tags?api_key=${API_KEY}`,
    {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({
        name: 'Primary Senders',
        color: '#4CAF50'
      })
    }
  );

  const result = await response.json();
  console.log(result);
  ```
</RequestExample>
