# Procurement Service Bus
The Procurement Service Bus (PSB) provides a cloud managed connection to eDelivery networks like the Peppol network. Specially designed for large volumes and low latency with automatic scaling. Build with redundancy and high availability in mind. The shared cloud approach is centrally monitored for optimal utilization and predictable costs. Additional services are available, like target-transformation, automatic retry, party discovery, intelligent document recognition, Peppol and OASIS certified SMP, Peppol certified SML, Peppol AS4 certified Access point, multi channel discovery and so on.
The Procurement Service Bus is more than just an AccessPoint As A Service (APAAS). We connect the Peppol network with the enterprise systems.
The interface is based on REST with OAUTh 2.0 layer. The API’s are self explanatory and made visible with the OpenApi UI. The swagger.json file can be downloaded on top of the OpenAPI UI main page and can be used to generate code for several languages. If you choose to generate code, we recommend using OpenAPI Generator (opens new window).
