How to use sudo programmatically via a pipe?

I am trying to write a program to perform remote administration of a system. To this end, I issue SSH commands and provide input programmatically via a pipe. I also capture their output.

Some of the commands require elevation, so I need to issue commands such as

ssh user@host "sudo apt-get install blah"
.

The problem is,
sudo
refuses point-blank to accept a password via the terminal unless it finds a real terminal on its stdin. Is there some way I can fool
sudo
into allowing this?

Answer

echo 'password' | sudo -S command

-S accepts password from stdin
