What an API is and why it matters
API = Application Programming Interface
Short definition
An API is an interface that lets two systems communicate and exchange data automatically. In an ERP/CRM context, an API enables integrations - e.g. pulling orders from a shop or sending invoices to accounting.
An API (Application Programming Interface) is a set of rules that lets one program use another's functions or data. Instead of a human re-typing data between systems, the systems do it themselves - faster and without errors. The most common type is a REST API communicating over HTTP.
When choosing an ERP/CRM, an open, well-documented API is critical. It decides whether the system can integrate with marketplaces, accounting or your own tools. A closed or limited API is a common cause of vendor lock-in - because you cannot get your data out or connect what you need.
Open Mercato exposes an open REST API, which means full integration freedom and no vendor lock-in. It is also the foundation on which we build integrations with accounting systems and sales channels.
