# Pay Later OpenAPI specification
Pay Later allows shoppers to postpone the due date of an open invoice transaction between 14 and 150 days. Shoppers may use Pay Later to prevent getting dunned. It gives them the ability to plan their payments more individually. Charges apply when using this feature.
The Pay Later API enables sellers to integrate this functionality into their frontends. The Pay Later API offers endpoints to check the Pay Later status of a purchase order and to book a Pay Later option. By using the Pay Later API shops can offer their customers greater payment flexibility when paying by open invoice while keeping them inside their own frontends.
Booked Pay Later options can be withdraw within 14 days. Therefore the shopper can use one of the channels referenced in [Ratepay Pay Later Terms of Use](https://www.ratepay.com/legal-paylater/).
