Product triggering special actions

[dsaunier]

I could not find if and how I could do the following: I have a special product that will require a specific contract to sign, and will trigger a custom hook on being ordered.

Is it possible to have a PDF and custom message emailed to a client ordering that product, on top of triggering our custom hook not on payment for that order, but just on ordering it no matter if it's paid ?

 

Thanks.
