Cardmarket has had no public API since 2023. The stock import is the only bulk route in, and it is a CSV you upload yourself. Listrune builds that file from a batch.
You need a Pro or Powerseller account. The stock import is not available on a normal seller account.
Uploading
- Export the batch — the file downloads as
cardmarket-stock-….csv. - On Cardmarket go to Account → Stock → Import.
- Upload the file and read the result.
Test with two or three rows before trusting a full batch. Listrune's column set follows Cardmarket's published template, but it has not been validated against every account type.
The columns
| Column | What Listrune puts there |
|---|---|
idProduct | Cardmarket's own product id for that exact printing. Without it the row is rejected. |
count | Quantity. |
price | Your list price, always in euros — see below. |
condition | MT, NM, EX, GD, LP, PL or PO. |
language | Cardmarket's numeric language id, not a code. |
isFoil | Y or N — and it does not mean the same thing in every game. |
comment | Left empty. |
Prices are always in euros
Cardmarket sells in euros for everyone. If your Listrune account is set to another currency, the file is still written in euros, converted at the rate on the export.
Language ids
| Id | Language | Id | Language |
|---|---|---|---|
| 1 | English | 7 | Japanese |
| 2 | French | 8 | Portuguese |
| 3 | German | 9 | Russian |
| 4 | Spanish | 10 | Korean |
| 5 | Italian | 11 | Traditional Chinese |
| 6 | Simplified Chinese |
What isFoil means — read this one
This is the field most likely to cost you money, because Cardmarket uses one flag for three different ideas:
- Pokémon
- The flag marks a Reverse Holo. A Holo Rare is its own separate product and must not be flagged, or it lists as the reverse — usually the cheaper card. Listrune flags only reverse holos.
- Magic
- The flag is the foil treatment, and covers etched foils too.
- Yu-Gi-Oh!
- Rarity is part of the product itself, so nothing is ever flagged.
Rows Listrune holds back
Any card without a Cardmarket product id is left out, with the reason on the row. The stock
import rejects rows without idProduct, so sending them would just produce a longer
error report.
Magic cards get their id from Scryfall automatically. For Pokémon and Yu-Gi-Oh! it is not always in the source data — you can type the id onto the card in the batch editor, and the row becomes exportable.
