I can't find any doc about this subject that could bring me a solution, then here I'm:
I already created many projects using API calls, via Snaplogic and even updated them in the same way, but what doesn't work is the action attachTemplate as below:

this was supposed to add a new Template to a existing project, but when I use PUT passing the update parameters it returns error code 422.
