FAQ
Does it work with CS-Cart and Multi-Vendor?
Section titled “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 FedEx account for everyone or let each vendor connect their own.
CS-Cart already has a FedEx (REST) module. Why this add-on?
Section titled “CS-Cart already has a FedEx (REST) module. Why this add-on?”The core module (CS-Cart 4.18 and later) only fetches checkout rates, one service per shipping method. This add-on adds what a shipping desk needs: labels in PDF, PNG or ZPL, multi-package shipments, customs lines and the commercial invoice, return labels, cancel, pickups, tracking with scan events, address validation, safe retries, per-vendor accounts and a log. It also works on CS-Cart 4.17.2, where the core only has the retired SOAP module. It does not touch the core module and can run next to it.
Do I need a FedEx account?
Section titled “Do I need a FedEx account?”Yes: a FedEx account number and a project in the FedEx Developer Portal. The sandbox works without shipping anything. FedEx has to approve your production key.
Can a label be bought twice by mistake?
Section titled “Can a label be bought twice by mistake?”The add-on is built to avoid it: a lock per order, a stored attempt for every purchase, and a hold (“Unresolved”) when FedEx might have created the shipment but the answer was lost. See Usage.
Which CS-Cart versions are supported?
Section titled “Which CS-Cart versions are supported?”4.17.2 to 4.21.x.
Where are my credentials stored?
Section titled “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?
Section titled “Does it send data to Kavio Labs?”No. The add-on talks to FedEx only. The license check sends your domain name to the Kavio Labs license server once a day (Kavio Labs downloads).
What happens when FedEx is down?
Section titled “What happens when FedEx is down?”Rates: the method is hidden, or your fallback rate is offered. Labels: jobs wait and are retried automatically (5 minutes up to 12 hours) when FedEx did not process the request; when the outcome is unknown the attempt is held for you to check, so no label is bought twice.
What happens when the license expires?
Section titled “What happens when the license expires?”New work stops (no new rates, labels or pickups). Tracking of shipments that already exist and the queue keep running.
How do I get updates?
Section titled “How do I get updates?”Install the new package over the old one. See Installation.

My license shows “Pending verification”
Section titled “My license shows “Pending verification””This status appears in older add-on versions when you use a CS-Cart Marketplace license number that our license server has not matched with the Marketplace yet. The add-on is fully working in this state: no feature is switched off and you do not need to do anything. Newer versions show it as Active (Marketplace license). We confirm Marketplace numbers on our side; click Check now on the add-on’s License tab (Add-ons → Manage add-ons → the add-on) a little later and it shows Active. If it has not changed after 24 hours, contact support with your Marketplace order number.
Still stuck?
Section titled “Still stuck?”Work through the troubleshooting guide, then contact support with your CS-Cart version, edition, PHP version and the add-on version (1.0.0).
