Klarna Docs - Product file.

Product file.

The file should be placed at an HTTPS or FTP address from which we can retrieve it. If you have blockages at IP address level, ensure that our IPs (,, and have access. Refrain from using timestamps or other information that will change the URL of the feed as this will cause your products to disappear.

For us to optimize update routines and display your product catalog’s recent version with prices and item availability, we highly encourage the last-modified HTTP response header to be provided and serviced. The header indicates the date and time the product feed was last changed. By servicing this regularly, we can check for updates more frequently.

Use one of the following encodings for the price file:

  • UTF-8, UTF-16
  • ISO-8859-1
  • Windows-1252

We can handle the majority of formats. The most common are: TEXT/CSV, XML and JSON. Note that the price file can’t be in Excel or any other non-text format. To make our processing and your updates run faster, compress your feed using gzip/zip.


When it comes to a CSV feed, the data have to be structured in rows and columns. Each row must represent a single product and each column should consist of fields with product information.

  • Divide each field or column by a particular separator. Recommended separators include a tab, pipe, semicolon or comma.
  • Use "field qualifiers" at the start and end of each field. Note that this character might not occur within a field. Recommended “field qualifiers” single ( ‘ ‘ ) or double ( “ ” ) quotation marks.
