An application programming interface (API) is a defined way for two systems to talk to each other. API integration links procurement platforms, ERP, finance, supplier catalogues and marketplaces so information such as orders, invoices, prices and stock flows between them without manual re-keying. Because the exchange is structured and often real time, it keeps data consistent and processes fast.

For procurement, APIs enable capabilities like live catalogue and price updates, automatic order and invoice transfer, and punchout connections to marketplaces. They complement standards such as cXML, OCI and EDI, and reduce the errors and delays of moving files by hand. Well-integrated systems are the backbone of scalable, automated purchasing.
