stripe return to merchant/ecommerce

Hello, I have another question: I do a payment with sources with stripe system, at end I come at "return to ecommerce". I either can not click on that button and so payment is not executed. Return url problem or something, can someone check? I think it has to do with this: let sourceParams = [login to view URL](withAmount: UInt(mount), name: "Kurt Warson", returnURL: "roosenleuven://stripe-redirect", statementDescriptor: "ORDER AT11")
