Hi guys.
i am trying to create subscription on a future date and for that i am using subscription schedule api
below is an image of a call from api connector
which is giving me an error below
i have a test card attached to a test customer i have a customer in my stripe portal with an attached payment method.
so my question is does subscription schedule works with a test card as it always ask me to pass a customer value which i am passing as a customer id.
please guide me if i am making any mistake or i am missing something.
regards
