Unable to Fetch twitter tweets - twitter

Question

I am getting twiiter feeds now a days. I am using tweetinvi Api, my code fetch only latest 200 feeds,and i want all.
my code is
Public Function getTweets()
''Set the credentials
Dim lObjConsumerKey As String = "[REDACTED]"
Dim lObjConsumerSecret As String = "[REDACTED]"
Dim lObjUserAccessToken As String = "[REDACTED]"
Dim lObjUserAccessSecret As String = "[REDACTED]"
Auth.SetUserCredentials(lObjConsumerKey, lObjConsumerSecret, lObjUserAccessToken, lObjUserAccessSecret)
Dim lObjDataTable As New DataTable
lObjDataTable.Columns.Add("Tweets")
lObjDataTable.Columns.Add("CreatedAt")
Dim GetTimelineTweets = Timeline.GetUserTimeline(txtUserName.Text)
For Each lobjGetgetTweets In GetTimelineTweets
Dim drNew = lObjDataTable.NewRow
drNew("Tweets") = lobjGetgetTweets
drNew("CreatedAt") = lobjGetgetTweets.CreatedAt
lObjDataTable.Rows.Add(drNew)
Next
Return lObjDataTable
End Function

Answer 1

This behavior is by design, as per the Twitter REST API documentaion for GetUserTimeline(). In the definition of the count parameter...
Specifies the number of Tweets to try and retrieve, up to a maximum of
200 per distinct request.
To get all tweets, check out Working With Timelines on the Twitter Developer site.

I have created a sample for you in the documentation : https://github.com/linvi/tweetinvi/wiki/Get-All-User-Tweets
RateLimit.RateLimitTrackerMode = RateLimitTrackerMode.TrackAndAwait;
RateLimit.QueryAwaitingForRateLimit += (sender, args) =>
{
Console.WriteLine($"Query : {args.Query} is awaiting for rate limits!");
};
long userId = <YOUR_USER_ID>;
var lastTweets = Timeline.GetUserTimeline(userId, 200).ToArray();
var allTweets = new List<ITweet>(lastTweets);
var beforeLast = allTweets;
while (lastTweets.Length > 0 && allTweets.Count <= 3200)
{
var idOfOldestTweet = lastTweets.Select(x => x.Id).Min();
Console.WriteLine($"Oldest Tweet Id = {idOfOldestTweet}");
var numberOfTweetsToRetrieve = allTweets.Count > 3000 ? 3200 - allTweets.Count: 200;
var timelineRequestParameters = new UserTimelineParameters
{
// MaxId ensures that we only get tweets that have been posted
// BEFORE the oldest tweet we received
MaxId = idOfOldestTweet - 1,
MaximumNumberOfTweetsToRetrieve = numberOfTweetsToRetrieve
};
lastTweets = Timeline.GetUserTimeline(userId, timelineRequestParameters).ToArray();
allTweets.AddRange(lastTweets);
}
// `allTweets` now contains all the tweets that Twitter can return
