# Tag a customer

```http
PUT https://secure.yoprint.com/v1/api/store/{team_slug}/customer/{hash_id}/tag/attach
```

- API version: v1
- Operation ID: `v1_public_customer_tag_attach`
- Section: Customers › [Customers](https://developer.yoprint.com/reference/customers.md)
- Web page: https://developer.yoprint.com/reference/customers/v1-customer-tag-attach/
- Authentication: `Authorization: Bearer YOUR_API_KEY`

Puts one of your team's tags on the customer and returns the customer's tags. Tagging a customer twice with the same tag changes nothing. Create tags with Create a tag.

## Permission

Any member of the team.

## Path parameters

- `team_slug` (string, required): Your team slug, shown as Team ID next to your API key in Profile. Example `your-team`.
- `hash_id` (string, required): The customer's id (`id` from List customers or Create a customer). A hash id from an earlier answer; unique keys and document numbers (such as `PO0042`) don't work here. Example `EDhVUaC6jbLbed`.

## Request body

Content type `application/json`, required.

Fields:

- `id` (string, required): The tag id.

### Example request

```bash
curl -X PUT 'https://secure.yoprint.com/v1/api/store/your-team/customer/EDhVUaC6jbLbed/tag/attach' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Accept: application/json' \
  -H 'X-Yoprint-Decimal-Format: exact-v1' \
  -H 'Content-Type: application/json' \
  -d '{
    "id": "zzVW0sylTIm6oo"
  }'
```

## Response

`200` Successful response.

Fields:

- `data` (array of objects, required): Every tag on the customer after the change.
  - Each item:
    - `color_hex` (string | null, required): Such as `#2563EB`. Null for a tag saved without a color.
    - `id` (string, required)
    - `name` (string, required)
- `status` (integer, required)
- `success` (boolean, required)

Example response:

```json
{
  "data": [
    {
      "color_hex": "#2563EB",
      "id": "zzVW0sylTIm6oo",
      "name": "Wholesale"
    }
  ],
  "status": 200,
  "success": true
}
```

## Errors

- `401` The API key is missing or wrong (`unauthenticated`).
- `403` You are not allowed to do this. `api_access_not_in_plan`: your team's plan doesn't include API access (Pro and above, with an active subscription or trial), so every request answers this until the team upgrades. When your role lacks the permission the operation needs, the body is only `{"message": "Insufficient Permission"}`. Other refusals use the error envelope, with `unauthorized` or `user_is_not_authorized`.
- `404` Not found. `page_not_found`: the team slug is unknown, you are not a member of the team, or an id in the path is not one of this team's. `code: null`, with a message that starts "No query results for": there is no record with that id.
  - When: No tag, or no live customer, with this id in the team, or `id` is missing. `error.code` is null and `error.message` names the record type. Fix: List tags to find the id.
