Hello guys

I've recently taken participation in a music project (feel free to check us out at @lettherebmusic) where we tweet music info about a certain topic every day. I actually use tweetdeck to schedule tweets for the whole day, so that content is available all day long. The thing is, it's exhausting to input every tweet individually, so I've thought of a way of inputting the whole content, and have a webpage process it to separate every tweet individually... All that I'm missing is the API call to schedule the tweet. Anyone know how?

Tl;dr I need to know what's the API call in software like tweetdeck or hootsuite that lets you schedule tweets.

P.S. I have thought of the possibility that this is a standalone software that loads tweets from a database and feeds them to the API to post them at the time they are programmed. Could there not be a schedule API call, and instead be this the way these softwares work?
