Hello Priyanka,

First of all, I could not understand your query, still, I would like to answer by making some assumptions:-

Do you need IIIT M.Tech  application link form? If yes then it is here  https://admissions.iiitd.ac.in/mtech/register.php 

If you want someone else to fill your form then you have to provide him all required documents.

By the way All the best.
