Our API explained in brief

The Dual Delivery API from Post Business Solutions seamlessly combines digital and physical delivery within an automated workflow.

Submit your item data via an interface and the system automatically checks whether recipients are registered for the e-letter service. Your item is then delivered either electronically or physically. This allows you to intelligently combine e-letter delivery and transactional printing within your own systems, ensuring that each item takes the most cost-effective, efficient and reliable delivery route.
