Infusionsoft + Trustpilot

looking for a way to integrate Trustpilot with Infusionsoft
one way is to add the unique email adress as BBC
but when i try to sent a test… something is going wrong…I don’t receive an email from Trustpilot upon a payment
the second way is to add a javascript but i didn’t find a solution for it
may be someone knows which is a way?
