Currently we can access 1on1 DM via Twitter API but not group conversations. If we forcibly set the group's conversation_id, Twitter API returns forbidden. Allow this.

Tweet threads have become increasingly popular over the past few years. This API would enable developers to tap into the potential of threads by programmatically creating threads, as well as retrieving all Tweets in a thread.

Create endpoint for get "quote tweets" by other to Tweets authored by the user. Like endpoint statuses/retweetsofme.

It would be really helpful to have an analytics endpoint in which the entity was a media ID (in my case a video ID) and you could request engagement & video metrics aggregated at the video level, even if that video appeared across many different tweets. Right now this is possible through the Engagement API for video views only, but it would be great if it were available through the Ads API & included seconds/minutes viewed, percentile completions, call to action clicks, etc.

I would like to recommend building a conversations API that enables developers to track updates to full conversation threads. This API would retrieve the entire conversation that a Tweet is in, and return all Tweets and replies within a given thread. This API would enable developers to go from a Tweet of interest to all replies in the thread, without having to recursively search for Tweets with the correct "inreplytostatusid".

We need a way to manage muted keywords, similar to the existing endpoints for muted users:

GET mutes/keywords/list
POST mutes/keywords/create
POST mutes/keywords/destroy

Surface is the first tweet in the hashtag, to know the founder of the hashtag, it is his right; and also there are those who use the hashtag for no purpose intended for topic of the hashtag (no objection to it), but you are tired to reach the news for which the hashtag was founded due to the large number of tweets outside the same topic.

Having access to an API for Twitter native polls would enable developers to create and schedule polls, as well as get back engagement data such as impressions, responses, Retweets of the poll, and their resulting responses, reach, and total engagement.

I was trying to summarize a conference in a moment with over 64 tweets. Trying to organize those manually moving them up and down 1-by-1 on the site was a pain (as many people tweet things not quite in chronological order of the conference or if you sorted once and want to add more later, it's hard).

It'd be great to expose the API for creating/editing moments so that other tools could help push the experience of capturing events or help to correlate topics and insert into proper places.

It would be useful to be able to retrieve more than 100 results calling GET statuses/retweeters/ids
The current limitation doesn't make sense.

Twitter could build a more affordable version of the enterprise Engagement API, which would provide developers with Tweet metrics for owned Tweets.

Engagement data returned by the API includes number of Likes, Retweets, replies, impressions, and engagements (for example, number of link clicks). This API would enable developers to better understand their reach and impact on Twitter.

It will be really useful to be able to accept/deny follower requests with Twitter API when tweets are protected.
This feature exists but currently this is not public.

When I try to call this endpoint :

POST https://api.twitter.com/1.1/friendships/accept.json?user_id=<follower id>

I've received : {"errors":[{"code":37,"message":"Not authorized to use this endpoint."}]} - HTTP Code : 403

I would like the Twitter API to use OAuth 2.0 instead of OAuth 1.0. OAuth1.0a is fairly specific to the Twitter APIs at this point in time. It's complicated to implement, and there is a dwindling number of developer tools that support it. OAuth 2.0 is less complicated and easier to build into an app than OAuth 1.0.

At www.contexto.io and www.graphext.com we provide our customers the possibility of mapping and expanding Twitter communities leveraging the social graph. This allows us to get really contextual, relevant and different insights that most social media analytics tools offer (they mostly count keywords that matches a boolean query).

We currently use the free API following/followers endpoints for this right now but with the new policy starting this month we cannot make more than 100K requests/day which prevent us from scaling our product. We would be very happy to pay for a premium endpoint like this!

Add more trending stations/places, like for north Indians its only Delhi.
