An API (Application Programming Interface) is a set of rules that lets two software systems share information and work together. Think of it as a conversation between two apps. They might be built differently, but the API helps them exchange data clearly, consistently, and securely.
An API acts like a bridge between two systems, telling them how to ask for and send information. For instance, a weather app doesn’t track the weather itself: it uses an API to pull forecasts from a weather provider. The app doesn’t need to see the provider’s internal workings; it just asks for the right data and gets it in the correct format.
In marketing tech, this kind of connection is crucial. APIs help different tools like CRMs, email marketing platforms, and analytics tools work together by syncing data behind the scenes. This means marketers can fully understand customer behaviour without jumping between systems. For example, actions like email engagement or website visits can be automatically pulled into a single platform.
While developers or data teams often use APIs, marketers benefit, especially when setting up integrations or automating manual tasks.
