Answer 1

Refer this and Create your developer account on twitter,by your own key, ouath will work.refer this create secret key for oauth

Answer 2

use this method, it would work correctly
<cfset consumerKey = "xxxxxxxxxxxxxx">
<cfset consumerSecret = "xxxxxxxxxxxxxxxxxxx">
<cfset bearerToken = ToBase64(consumerKey & ":" & consumerSecret)>
<cfset authorization = "Basic " & bearerToken>
<cfhttp url="https://api.twitter.com/oauth2/token" method="post" charset="utf-8" >
<cfhttpparam type="header" name="Authorization" value="#authorization#">
<cfhttpparam type="header" name="Content-Type" value="application/x-www-form-urlencoded;charset=UTF-8">
<cfhttpparam type="body" value="grant_type=client_credentials">
</cfhttp>
