I want to get the whole twitter thread content. with the conversation id. But the problem is it only pulls the recent one. Is there another way to get the thread contents all together.
#thread #api

How exactly are you calling the API now? Using what code and what queries?

If you don’t have academic access, you are limited to the last 7 days of tweets from the search endpoint.

So I did /search/recent but it doesn’t get older tweets ,
and /2/tweets?ids=:conversation id , does’nt have filtering option ,
and the stream api is working only for words and stuff , not for from: username and conversation_id : id

Yes that is right. Recent search only goes back 7 days, looking up tweets you need to already know their IDs, and streaming API is for brand new tweets only.

Although from: should work as a rule in the stream and so should conversation_id: Filtered stream - How to build a rule | Docs | Twitter Developer Platform

Give twarc a try, you can define rules and open a stream in the command line:
