[RESOLVED] Product Ranking Endpoint Returning No Data

After the rollout of the change to the product ranking endpoint, a bug was introduced affecting the Accept-Language parameter in the header, causing only "nl" and "fr" to be returning data. This issue has now been resolved, and as of this afternoon you should be able to use all headers as described in the API specification.

Note: It is still possible that no data will be returned for some of your products. As mentioned in the announcement post, due to the definitional change and the improved method of measuring impressions, significant differences in the data are expected.
