[Solved] Unity IAP Validate Purchase

Hello there, after I purchase an item I want to validate the purchase in playfab with a request call. The problem is this request call reqruies receipt and signature. I could only find the receipt parameter in unitys Product class, where is the googles signature key? Or is the name of the paramater different?

Nevermind, Payload josn has the signature key.
