A native Windows application can call the HTTPS endpoint with libcurl or another HTTP client.

C++ / libcurl

CURL* curl = curl_easy_init();
if (curl) {
    const char* json = R"({
      "app":"YOUR_APP_NAME",
      "owner_id":"YOUR_OWNER_ID",
      "version":"1.0",
      "license":"YOUR_LICENSE_KEY",
      "hwid":"YOUR_DEVICE_HWID"
    })";
    curl_easy_setopt(curl, CURLOPT_URL,
        "https://YOUR-DOMAIN/api/v1/license");
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, json);
    // Add Content-Type: application/json and capture the response.
    curl_easy_perform(curl);
    curl_easy_cleanup(curl);
}
