USPS "retiring" unsecure (http://) API URL

[lat9]

Per the USPS release notes (https://www.usps.com/business/web-to...ease-notes.pdf), the unsecure (http://production.shippingapis.com/shippingapi.dll) will be 'retired' later this month. Instead the API URL should change to https://secure.shippingapis.com/ShippingAPI.dll.

In the USPS-2018-03-28 K10 version of the USPS shipping-module, you'll need to edit /includes/modules/shipping/usps.php, starting at line 1298 (similar changes will be needed for prior versions, but you should update in that case anyway):

    switch (MODULE_SHIPPING_USPS_SERVER) {
      case 'production':
      $usps_server = 'http://production.shippingapis.com';
      $api_dll = 'shippingapi.dll';
      break;
      case 'test':
      default:
// 09-7-2014
//Secure APIs: https://stg-secure.shippingapis.com/ShippingApi.dll
//Non-secure APIs: http://stg-production.shippingapis.com/ShippingApi.dll
      $usps_server = 'http://stg-production.shippingapis.com';
      $api_dll = 'ShippingApi.dll';
      break;
    }

to read

    switch (MODULE_SHIPPING_USPS_SERVER) {
      case 'production':
      $usps_server = 'https://secure.shippingapis.com';
      $api_dll = 'ShippingApi.dll';
      break;
      case 'test':
      default:
// 09-7-2014
//Secure APIs: https://stg-secure.shippingapis.com/ShippingApi.dll
//Non-secure APIs: http://stg-production.shippingapis.com/ShippingApi.dll
      $usps_server = 'https://stg-secure.shippingapis.com';
      $api_dll = 'ShippingApi.dll';
      break;
    }

FYI: Downloads of the USPS-2018-03-28 K10 version after October 2, 2020 from https://www.zen-cart.com/downloads.php?do=file&id=1292 will include this correction.

(So you could download K10 again and use the /includes/modules/shipping/usps.php file to replace your current one, instead of doing the edits manually.)
