NodeXL Pro allows for 3rd party developers to create data importers that can integrate into the NodeXL Pro > Data > Data Import menu. In that menu you will also find a list of links to 3rd party importers currently available.
Flickr limits access to their API on a per key basis. Your should stay under 3600 queries per hour or flickr may block or terminate your access.
The only major limit of the public free Facebook is time. You can get as much historical data from fan pages and groups as you like, yet the network data download may take quite a while as the download stops and resumes.
Please note that the download of network data from large fan pages can easily max out your system memory if you do not limit the number of reactions, likes and shares when setting up the data importer.
The use of NodeXL Pro Twitter data importers requires a twitter account. Before your first data import you need to authorize NodeXL by entering a token number which is automatically sent to you during the authorization process.
Moreover Twitter’s public free API has many limits. NodeXL Basic and Pro are both effected by these limits. Data is available only for 8-9 days. Queries cannot return more than 18,000 tweets.
The follower network is further restricted: the rate at which queries about who follows who can be asked is low.
NodeXL Pro does not enable the collection of data beyond these limits. That said, NodeXL can process data from commercial data providers (like Crimson Hexagon or Radian6). While these are expensive options, they may be the only way to get historical data from Twitter.
Commercial services like Radian6 and Crimson Hexagon might provide archival data – but not cheaply!
You may be able to get a little bit more data from the public Twitter API by using the SINCE: and UNTIL: operators – example:
QUERYTERM since:2016-01-21 until:2016-01-27
Since: and Until: operators scope the time frame of the query.
Twitter controls its API and throttles it based on unknowable parameters. We notice that the more the volume of tweets == less tweets delivered.
One alternative is to do day long slices and append them in order to maximize the data available from Twitter.
