Outlet and clearance products are not allowed.
Products from the previous collection must be unpublished within one month after the last day of the current season's sales.

Multi-country settings

The countries where you wish to publish your products must be activated in your Mirakl back-office.

  • If you're publishing your products in one country only (and you have one active channel in your Mirakl back-office), use the following attributes:

"price", "discount-price", "discount-start-date" and "discount-end-date" for your promotions.

  • If you're publishing in several countries (and you have several active channels in your Mirakl back-office), you have to fill in the offer attributes specific to each country, containing "channel=XX".

For example for the French market, fill in "FR" offer attributes:

  • "price[channel=VBFR]"
  • "discount-price[channel=VBFR]"
  • "discount-start-date[channel=VBFR]" (mandatory if a discounted price is sent)
  • "discount-end-date[channel=VBFR]" (mandatory if a discounted price is sent)

For example for the German market, fill in "DE" offer attributes:

  • "price[channel=VBDE]"
  • "discount-price[channel=VBDE]"
  • "discount-start-date[channel=VBDE]" (mandatory if a discounted price is sent)
  • "discount-end-date[channel=VBDE]" (mandatory if a discounted price is sent)

When publishing across several countries on the marketplace, the offer quantity is shared and cannot be customised separately for each country.
