What does Integration mean?

Integration refers to connecting two or more systems, applications or services so that they can automatically exchange data or use each other's functions. In e-commerce, this can mean connecting an e-shop with a payment gateway, carrier, accounting system, CRM, warehouse, marketplace or analytics tool. Integration helps reduce manual work, speed up processes and keep data up to date across different systems. Technically, it can be done through APIs, connectors, plugins or data feeds. A good integration should be stable, secure, properly documented and ready for changes in the connected systems.
