Both follow-up CIT and MIT payments are available with the same token. For recurring payments, customers can easily cancel the mandate at any time within their app — in such cases, Solidgate cancels the subscription and notifies the merchant. The notification about a cancelled mandate is only available to payment providers that can notify when the payment method is no longer linked.
Only one active mandate is allowed per customer per merchant. Since a mandate is generated only during the initial payment, any upsells or additional subscriptions must use the existing recurring token.
