We already have announced in the article “Breaking changes when using the Facelift Data Studio API - 25th of April, 2018” that Facebook is going to change the naming and definition of the following data sources in the Facebook Insights API:

In this article we will dive more into the changes of the FacebookInsightsPageLikesAndUnlikesBySource as the big impact here is on the returned values of the fields.

FacebookInsightsPageLikesAndUnlikesBySource holds the number of won and lost Page Likes of Facebook Pages including their development over time. It contains also the sources of each Page Like.

Before the change, the Facebook Insight API was returning over 40 sources. But after that, it will just return less than 10 sources. Hence some sources will be aggregated.

One of the affected metrics is our default metric “Fans Change by Like/Unlike Source” which uses the data source “FacebookInsightsPageLikesAndUnlikesBySource”. Here you can see the different sources you will retrieve before and after the changes:

Before the change results of the Facebook page “Facelift Data Studio” for the first quarter of 2018:

After the change results of the Facebook page “Facelift Data Studio” for the first quarter of 2018:

Through our reverse engineering by comparing the result of the API before and after the change, we were able to compose the mapping.

Mapping by reversed engineering:

likes / likesUnique

*The mapping needs to be handled with caution as we already detected some inconsistency in the mapping of "Page Suggestion" and "Others".
