As of September 4, 2019, Facebook is discontinuing access to the Page Public Content API. This API is what enables third-party apps such as Netlytic to collect publicly available posts and comments for research.
We realized how important this API is to some of our academic users. To ensure continuing access to this API, we are in the process of submitting Netlytic to Facebook for an App Review.
Unfortunately, the outcome of the App Review process is unpredictable and we’re not able to guarantee access to Facebook Public Pages beyond September 4, 2019.
We’ll post another update as soon as we have more information.
