InPost Shipping & Labels: InPost Parcel Lockers at checkout, ShipX labels and tracking from the order page1 of 7
What it does
For stores that ship within Poland. InPost is the Polish parcel locker network and courier carrier. The add-on offers two shipping methods, Parcel Locker and Courier, with the prices you set per parcel size, and connects them to your own InPost ShipX account (organization id and API token) in sandbox and production. You need an InPost business account.
How it works
Connect with your own sandbox credentials, test the connection, then enter the production values. The customer picks a locker on the InPost map or types its code. In the order, Create label sends the shipment to InPost, which confirms it within seconds; the add-on then downloads the label and follows the status through webhooks and cron. Failed jobs are retried automatically and listed in the log.

Initial release: InPost ShipX integration for Poland.
Shipping services Parcel Locker (inpost_locker_standard) and Courier (inpost_courier_standard) with customer prices from the add-on settings (sizes A, B, C and courier).
Parcel Locker picker at the checkout with the InPost Geowidget v5 or by locker code; the locker is stored with the order and shown on documents; reuses the locker of EU Pickup Points & Parcel Lockers.
ShipX shipments from the order page or at an order status: receiver, parcel template or dimensions, target_point, cash on delivery and insurance in PLN; asynchronous confirmation completed by the queue.
Labels in PDF or ZPL (normal or A6), tracking number and link on the order and in a CS-Cart shipment, cancel while the shipment is in the created state.
Status follow-up by InPost webhooks (secret key in the URL) and cron; Multi-Vendor owner mode or one organization per vendor.
Connection page with encrypted credentials, test and live mode and a connection test.
Job queue with retries and back-off, cron (command line and secret address), log viewer with CSV export.
Tested on Multi-Vendor 4.17.2. First release.
Does it work outside Poland?
No. This add-on uses the InPost ShipX API of Poland: Polish addresses, PLN, parcel lockers (Paczkomat) and courier within Poland.
Do I get the real InPost price at checkout?
No. ShipX returns the price of your own contract only for shipments you create, not as a price list for your customers (and not at all for debit accounts). You enter the price you charge per parcel size and for the courier.
Does it work with EU Pickup Points & Parcel Lockers?
Yes. If an order was placed with the InPost method of that add-on, its stored locker is used for the label. Without it, this add-on shows its own locker picker.
Does it work with CS-Cart and Multi-Vendor?
Yes. The add-on supports CS-Cart and Multi-Vendor. In Multi-Vendor the marketplace owner can use one InPost account for everyone or let each vendor connect their own.
Which CS-Cart versions are supported?
4.17.2 to 4.21.x.
Where are my credentials stored?
In your own database, encrypted. The key is derived from your store's secret in config.php, so a database dump alone does not reveal them. They are never shown again after saving.
Does it send data to Kavio Labs?
No. The add-on talks to InPost only. The license check sends your domain name to the Kavio Labs license server once a day (Kavio Labs downloads).
What happens when InPost is down?
Jobs fail, wait and are retried automatically (5 minutes up to 12 hours). Nothing is lost and nothing is sent twice.
What happens when the license expires?
New work stops (no new documents, rates, syncs or payments). Work already under way is still finished.
How do I get updates?
Install the new package over the old one. See Installation.
Add a released add-on to this order and save 15% on it. It uses the same edition and store domain.
