Confirm acceptance of Terms and Conditions for Tap and Pay

i am implementing the Tap and Pay for stripe terminal during this i want to check whether the merchant accepted the terms and conditions or not using the isAccountLinked(using:) but this method requires the parameter - "The token from your payment service provider. This token contains the merchant identifier." i cannot find any other reference for the merchant identifier how to retrieve or how to get it as per stripe support they said you need to contact the apple support.
