I'm trying to create a discord bot with notification about new tweets.
I am using T.stream('statuses/filter', { follow : ['798934987978510337'] });
for this, but it show mentions too.
Can I get only tweets from user with twit?
No, the statuses/filter
streaming API does contain retweets as well. You will need to filter out retweets in your own code if you do not want to pass them over to Discord.
