Trace

Use case

Package tracking API for WooCommerce

WooCommerce stores ship through dozens of carriers, and there's no built-in multi-carrier tracking API. Each order's tracking number comes from whichever shipping plugin generated the label.

Trace gives WooCommerce merchants a single endpoint: send the tracking number, get normalized status and events, and display them on the order page or in a custom status page.

How it works

  1. 1Generate an API key in the Trace dashboard.
  2. 2Read the tracking number from the WooCommerce order or shipping plugin.
  3. 3POST it to /v1/track and display the normalized status and events.

$ch = curl_init("https://api.traceapi.dev/v1/track");
curl_setopt_array($ch, [
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => [
        "Authorization: Bearer " . getenv("TRACE_API_KEY"),
        "Content-Type: application/json",
    ],
    CURLOPT_POSTFIELDS => json_encode(["tracking_number" => "1Z999AA10123456784"]),
]);
$tracking = json_decode(curl_exec($ch), true);
curl_close($ch);
