# Update Email Account Tag

> Update an existing email account tag's name and color

<Note>
  Update an existing tag's name or color. To **create a new tag**, use the [Create Tag](/api-reference/email-account-tags/create-new) endpoint instead — it does not require an ID.
</Note>

  Your SmartLead API key
</ParamField>

## Request Body

<ParamField body="id" type="number" required>

</ParamField>

<ParamField body="name" type="string" required>
  Tag display name
</ParamField>

<ParamField body="color" type="string" required>
  Hex color code for the tag (e.g., `#FF5733`). Must be a valid 6-character hex color with `#` prefix.
</ParamField>
