title: tweeting using "@" and "#" through tweeter api
body: <p>I am new to tweeter api(beginner level experience), have been exploring tweeter rest api. so far I managed to read user timeline, followers count and also able to tweet.</p>
  
  <p>However in a tweet, I wish to mention users by using "@" symbol.
  example something like this.</p>
  
  <p><a href="https://i.stack.imgur.com/HLL8T.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HLL8T.png" alt="This is how I am Entering mentions"></a> </p>
  
  <p>This is not working,  also the same case with hashtags "#"
  getting error as 
  <a href="https://i.stack.imgur.com/pGmTQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pGmTQ.png" alt="Error when @ is used"></a></p>
  
  <p>If I remove "@", then it works and posts a message.</p>
  
  <p>Also referred the reference api <a href="https://developer.twitter.com/en/docs/tweets/post-and-engage/api-reference/post-statuses-update" rel="nofollow noreferrer">https://developer.twitter.com/en/docs/tweets/post-and-engage/api-reference/post-statuses-update</a> </p>
  
  <p>However neither could i figure out any relevant parameter that I can use nor able to find any example while surfing.</p>
  
  <p>For this POC, Twitter standard api is used(Just thinking if this feature is allowed in standard api) </p>
  
  <p>Thanks and appreciate any advice/guidance </p>
