Sypost Express WooCommerce Plugin

Description: The Sypost Express plugin is a custom WooCommerce extension designed to enhance the order management process by integrating with the Sypost API. It provides a seamless way to modify order meta, manage shipping details, and generate shipping labels directly from the WooCommerce admin dashboard.

Key Features:

  1. Order Meta Modification: Easily modify and view shipping method codes and shipping number codes for each order.
  2. Dynamic Shipping Price Retrieval: The plugin fetches available shipping methods based on the destination country and displays them for selection.
  3. Shipping Label Generation: Once an order’s shipping method is selected and confirmed, the plugin communicates with the Sypost API to generate a shipping label, which can be downloaded in PDF format.
  4. Custom Settings Page: Manage API tokens and other essential settings from a dedicated settings page in the WordPress admin area.
  5. Error Handling: The plugin provides feedback on any errors encountered during the shipping label generation process, ensuring smooth operations.
  6. Security: The plugin ensures that it can’t be accessed directly, enhancing the security of your WooCommerce setup.


  1. Upload the plugin files to the /wp-content/plugins/sypost-express directory, or install the plugin through the WordPress plugins screen directly.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress.
  3. Use the WooCommerce->Settings->Shunyou Settings screen to configure the plugin (API tokens, etc.).


Once installed and activated, navigate to any order in the WooCommerce admin. You’ll see an additional section titled “Shipping Order” where you can select the shipping method, view/edit shipping method codes, and download the shipping label once generated.
