Access Template Create/Update/Delete for an User

Hi Gurtam Support,

I am using update_custom_property remote API to create access templates for an user but every time when I hit the API I am getting back error code 4 which is Invalid Input.

I wrapped all the parameter values with double quotes properly ( sample req show below ) , can you please let me know how to achieve this ?
