Data Limitations

Rakuten does not impose limitations on the amount of data that you can pull, but for products with a lot of reviews, you may want to limit it yourself using the Comment Limit option or by narrowing the date range.

If you have issues with no data, try widening your date range on the second page of the wizard.

Input fields

When setting up the connector, provide the URL of the product or products for which you want to analyze customer reviews. 

  • Rakuten Product URL (*required): On the Japanese Rakuten web site, navigate to the product and from the address bar, copy the URL, then paste it into this field.
  • Add new search: To analyze multiple product varieties or multiple products, click this as many times as needed to add more URLs.
  • Upload: Click to upload a file containing a list of product URLs. Takes a TXT file with one URL per line.
    (CSV is also acceptable, but it must have one URL per line.)
  • Comment Limit: It is a good practice to set a limit on the number of comments returned.

You can change your date range on the second page of the wizard, or optionally Schedule data crawls to update your data stream periodically.
