What exactly does 'since_id' and 'max_id' mean in the Twitter API
I've been poring over the Twitter docs for some time now, and I've hit a wall how to get stats for growth of followers over a period of time / count of tweets over a period of time...
I want to understand from the community what does since_id and max_id and count mean in the Twitter API.
I've been following this page https://developer.twitter.com/en/docs/tweets/timelines/api-reference/get-statuses-user_timeline
I'm trying to get stats for a user --
- counts of tweets in a particular time period
- count of followers over a particular time period
- count of retweets
I'd like some help forming querystrings for the above..
Thanks..

since_id and max_id are both very simple parameters you can use to limit what you get back from the API. From the docs:
since_id- Returns results with an ID greater than (that is, more recent than) the specified ID. There are limits to the number of Tweets which can be accessed through the API. If the limit of Tweets has occured since the since_id, the since_id will be forced to the oldest ID available.max_id- Returns results with an ID less than (that is, older than) or equal to the specified ID.
So, if you have a given tweet ID, you can search for older or newer tweets by using these two parameters.
count is even simpler -- it specifies a maximum number of tweets you want to get back, up to 200.
Unfortunately the API will not give you back exactly what you want -- you cannot specify a date/time when querying user_timeline -- although you can specify one when using the search API. Anyway, if you need to use user_timeline, then you will need to poll the API, gathering up tweets, figuring out if they match the parameters you desire, and then calculating your stats accordingly.
