How to create a Kelkoo feed


You will need to fill out the information in this contact form to begin the process of setting up your store and feed with Kelkoo


If you decide to submit your feed using an XML format, then the following recommendations will be helpful.

  • The name of your file must be in the following format “'<sitename>_kelkoo_<countryprefix>.xml”
  • Respect the name of the XML tags as shown in the Fields details table
  • To validate your XML file, it is preferable to insert the contents of the text fields in a CDATA section
  • The description often includes non-escaped specific characters such as &, >, or <. The CDATA section is not analyzed. Thus, we recommend using it if you do not take care to validate your XML Product data feed before sending it to us.


If you choose a text file, here are some recommendations:

  • Name your file ‘<sitename>_kelkoo_<countryprefix>.txt’ and save it in UNIX format / DOS
  • Use field separators to separate offers, the new line allows our system to distinguish between offers.
  • You can use any type of field separator.
  • Of course, the field separator should not be present within a same field (for example in the description). The tab will be the only field separator accepted for a the Kelkpack offer.
  • All offers must contain the same number of fields. If a field is blank, the field separator must be present.
