Question regarding permission to contact

Hey I have a question regarding the process of getting a permission to contact letter to play a sport at another school. I currently compete at a D2 school and am trying to get a permission to contact letter to a D1 school. I spoke with my current head coach and he said he would approve any request. I updated the coach at the other school. My question is for me to get this permission to contact do i have to do anything more or will the process be taken care of by the two institutions?
