Hi Manish,
As far as I know, the Twitter API does not provide any method to get the user's email, and as far as first and last name you will have to rely on the "name" field of the "user" entity. This may or (more likely) may not contain the information you are looking for. You can see a list of the fields contained in a user entity at : http://dev.twitter.com/doc/get/users/lookup Basically, if you need to those data, you are going to have the user for them yourself in your application. hax0rsteve On 21 Mar 2011, at 09:34, Manish Sadhwani wrote: > Hi > > I am having a web application in .net (3.5) and SQL Server.
