I learned that Facebook imports have changed. Can I still import data from Facebook?
Yes, there is still a way to pull data from Facebook pages, but Facebook shut off the full text search API. You will need to use a valid Facebook account to log in in order to import Facebook data.
Be sure to click on the Connect with Facebook button. For step-by-step instructions please see the Import Facebook data article.
We currently do not have access to the Facebook Firehose for Gnip. However, you can pull in Facebook data via the public API inside of DiscoverText, and we have found that it does a reasonable job of obtaining most, if not all, posts and comments for a particular page and/or query. With this, it will only allow you to go back at most 6 to 12 months depending on the amount of data).
