Prefix(@username) and Suffix(DM Deep links) are supporting excluding 140 characters?

That URL is NOT valid for use in that parameter.

In order for a URL to not be counted in the body of the Tweet, a new attachment_url parameter will be available on statuses/update to allow a client to attach it to the Tweet without explicitly adding it to the Tweet text. This URL must be a Tweet permalink, or DM deep link. Arbitrary, non-Twitter URLs should remain in the Tweet text and will count against the 140 character limit. URLs passed to the attachment_url parameter not matching either a Tweet permalink or DM deep link will fail at Tweet creation and cause an exception.

attachment_url parameter is not displaying any post in the tweet whatever the URL might be.
help me in suggesting that to post URL against 140 characters.

can you povide me the sample URL which is supported by twitter.
I have passed the permalink link too like below:

var params = { status: '@sivasai filter streams to find your target ', attachment_url: 'http://www.cscinco.com/event?e=58589bfc4f2fe526d999f8a1&u=5858bc8c4f2fe526d999f91c '} 

and DM deep link like below in the attachment_url parameter still unable to get any post in the tweet.

 var params = { status: '@LEADoid filter streams to find your target audience and then engage them within their own social post', attachment_url: 'https://leadoid.com/#!/home', media_ids: [mediaIdStr] }

T.post('statuses/update',{status: 'filter streams to find your target-http://www.cscinco.com/event?e=58589bfc4f2fe526d999f8a1&u=5858bc8c4f2fe526d999f91c'}, function(error, data, response){
  if(error){
    console.log(error);
  }
  console.log(data);  
  console.log(response);  
});

var params = { status: '@sivasai filter streams to find your target ', attachment_url: "http://www.cscinco.com/event?e=58589bfc4f2fe526d999f8a1&u=5858bc8c4f2fe526d999f91c" }
T.post('statuses/update', params, function(error, data, response){
  if(error){
    console.log(error);
  }
  console.log(data);  
  console.log(response);  
});

when I am executing the code-1 I am able to get the output post in the tweet. the URL is working with in 140
When I am executing the code-2 I am unable to see the post in the tweet not working against 140?

Yes, because that URL is NOT valid to as a value in the attachment_url parameter, as I’ve told you at least 4 times already in this thread. Please stop repeatedly asking for help on this. This behaviour is exactly as expected and as designed and will not change.

Non-Twitter URLs will not work in that parameter.
