API

Definition

An API (Application Programming Interface) is a programming interface that enables different software systems to communicate with each other. In marketing, APIs facilitate automated data transfer between tools — such as CRM systems, email marketing platforms, and analytics solutions. Through API integrations, workflows can be automated, data silos eliminated, and real-time personalization implemented. For enterprises in the DACH region, GDPR-compliant use of APIs for data transfer is particularly important.
