InPost Shipping for OpenCart 3

What you can do with the module

How it works in your store

1. The customer chooses delivery

   At checkout, the customer selects an InPost method and, where required, a parcel locker or pickup point.

2. The choice stays with the order

   The selected delivery information is saved with the order so your team can use it when preparing the shipment.

3. You review and create the shipment

   Check the address, parcel dimensions, service and any extra options before sending the shipment request to ShipX.

4. You print the label and hand over the parcel

   Print the available label, prepare the parcel and follow the selected InPost sending procedure.

Before you install

Platform

This installer is for OpenCart 3.x. It is not an installer for OpenCart 2.3 or 4.x. Check your exact OpenCart build before installing.

PHP and connectivity

OCS supports this installation on PHP 8.2 or newer. PHP cURL and OpenSSL, trusted TLS certificates and outbound HTTPS access are needed. Confirm your exact platform and PHP combination first.

Your InPost account

Prepare your own InPost ShipX API token and organisation ID, plus a suitable GeoWidget API key. Production and sandbox credentials are separate.

Checkout and theme

The package includes integration for the standard OpenCart checkout and Universal Checkout. Journal and other custom checkouts may need extra integration and should be checked first.

Product and parcel data

Check sender details, product weights and dimensions, parcel templates, service restrictions and your shipping prices. The module does not decide these business rules for you.

Get the module and activate your license

1. Complete the free order

   Add the module to your cart and complete checkout with your OCS customer account. The module price is zero; you still need to finish the order.

2. Download your installer and find your key

   Open Downloads for the available OCMOD package. Open Module licenses for the key assigned to this module purchase.

3. Install on a backed-up test store

   Use OpenCart Extensions > Installer, refresh Extensions > Modifications, then install InPost under Extensions > Shipping. Check for conflicts before changing a working checkout.

4. Activate, then configure InPost

   Enter the matching OCS key on the module’s activation screen. Add your own ShipX and GeoWidget credentials, sender details, delivery methods and service settings.

5. Test the full delivery flow

   Use the available sandbox settings to check point selection and shipment preparation. Before enabling production, check fees and services, labels, returns and scheduled tasks for your configuration.

A free module with a personal license key

Each purchased unit receives a key for one exact store hostname and this module only. example.com and www.example.com are different hostnames. Initial activation contacts OCS; the module then renews its signed activation automatically. An existing valid activation can work through a temporary connection problem only until its certificate expires, at most seven days.

Moving domains? Release the old domain in Module licenses, then use the newly generated key on the new store. A previous cached activation can remain valid for up to seven days after release or revocation. Ask OCS about staging or test domains.
