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

```shell
tracker_id="1234-5678"
private_key="your_private_api_key"
host="https://live.luigisbox.com"
path="/v1/recommender/pin/${tracker_id}/summary"
method="GET"
content_type="application/json; charset=utf-8"
date=$(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}" \

## How to Make a Request

1. Build the HMAC string from the method, content type, date, and request path.
2. Generate the signature with your private key.
3. Send the request with `Date`, `Content-Type`, and `Authorization`.
