According to the documentation I can get one recurring PayIn registration with this call to the api of mangopay GET .../v2.01/ClientId/recurringpayinregistrations/RecurringPayinRegistrationId
https://docs.mangopay.com/endpoints/v2.01/payins#e1052_the-recurring-payin-object
Do I have to save RecurringPayinRegistrationId in my database to retreive them all myself or does Mangopay store them in their database?
