## Request parameters

### Path parameters

| Parameter | Type | Required | Description |
| :-- | :-- | :-- | :-- |
| `TRACKER_ID` | string | ✓ | Your unique tracker identifier. |
| `CUSTOMIZATION_ID` | UUID | ✓ | The unique ID of the customization to retrieve. |

### Request headers

| Header | Value | Description |
| :-- | :-- | :-- |
| `Content-Type` | `application/json; charset=utf-8` | Required. |
| `Date` | HTTP date | Required for HMAC. |
| `Authorization` | `ApiAuth {TRACKER_ID}:{SIGNATURE}` | Required for HMAC. |

    <h4 class="code-section-title">Example Request</h4>

```shell
tracker_id="1234-5678"
customization_id="199620b4-df1a-46e8-ab59-9e9ed9af7106"
private_key="your_private_api_key"
host="https://live.luigisbox.com"
path="/v1/recommender/pin/${tracker_id}/scope/${customization_id}"
method="GET"
content_type="application/json; charset=utf-8"
date=$(date -u "+%a, %d %b %Y %H:%M:%S GMT")

string_to_sign="$(printf "${method}\n${content_type}\n${date}\n${path}")"
signature=$(echo -n "${string_to_sign}" | openssl dgst -sha256 -hmac "${private_key}" -binary | base64)

curl -X ${method} "${host}${path}" \
  -H "Content-Type: ${content_type}" \
  -H "Date: ${date}" \
  -H "Authorization: ApiAuth ${tracker_id}:${signature}"
```
  </div>
</ApiSection>

<ApiSection>
## How to Make a Request

1. Build the string to sign from the method, content type, date, and the full resource path including the customization ID.
2. Generate the HMAC SHA-256 digest using your private key.
3. Send the `Date`, `Content-Type`, and `Authorization` headers with the request.
