An authorization for a card payment is by default valid for 7 days. In order to actually receive the payment, the capture has to occur during these 7 days, while the authorization is still valid.
For specific needs
In order to meet the expectations of merchants and to address some use cases, SlimPay solution comes with a card authorization extension for merchants who would like to capture payments beyond 7 days.
Merchants can indeed need to extend the card authorization for example in case the payment is captured at the delivery date that can take place after 7 days.
