Return delivery fee from check response

Handling priceCents

The priceCents property is an integer in cents (e.g. 590 = €5.90). Divide by 100 for display or use directly with payment processors.

// PHP — server-side, keep API key out of frontend
$response = wp_remote_post('https://api.deliveryzone.fi/api/v1/delivery/check', [
  'headers' => [
    'X-Api-Key'      => get_option('dz_api_key'),
    'Content-Type' => 'application/json',
  ],
  'body' => wp_json_encode([
    'destinationPostcode' => $postcode,
    'basketValueCents'    => $basket_cents,
  ]),
]);
$data = json_decode(wp_remote_retrieve_body($response), true);
