Is there a way to get a tweet's favorite count?

Question

I couldn't find how to do this through the API documentation.

Answer 1

There is an undocumented way to get this information if you're authenticated.

https://api.twitter.com/i/statuses/[tweet.id]/activity/summary.json

An even larger list of API endpoints that are undocumented can be found in the Ruby Twitter library https://github.com/sferik/twitter/blob/master/lib/twitter/client.rb

Answer 2

The New API V1.1 Now supports the tweet favorite's count. Here try it out
