Cardmarket syncing uses the TCG STATS browser extension. The extension works while you are signed in to Cardmarket in a supported browser.
Install and connect
- Install the TCG STATS extension from the link shown in TCG STATS.
- Open Settings → Connections.
- Find Cardmarket.
- Enter your Cardmarket username when requested.
- Select Connect.
- Choose the TCG STATS location that owns the Cardmarket stock.
- Open Cardmarket and confirm that the TCG STATS panel appears.
What the panel does
The panel can show:
- new items waiting to be listed;
- quantity changes;
- price changes;
- Cardmarket stock ready to import.
The exact action depends on the Cardmarket page you have open.
Publish new listings
- Create the listings in TCG STATS.
- Open Cardmarket and sign in.
- Go to the Cardmarket bulk listing page.
- Open the TCG STATS panel.
- Process the waiting items.
- Continue through all batches until the panel is clear.
Update quantities
Open your Cardmarket stock or offers page before processing quantity changes. The extension needs that page to find and update your offers.
Import existing Cardmarket stock
Use the import option in the panel while viewing your Cardmarket stock. Review every imported match in TCG STATS before treating it as trusted inventory.
Common problems
The panel is missing
- Confirm the extension is installed and enabled.
