API is short for "Application Programming Interface". It is an interface that allows different applications to communicate with each other and exchange data. APIs simplify the design, administration and use of applications. New application components can be easily integrated into existing architectures thanks to APIs, which makes developers' work much easier. This flexibility can be critical for many companies in a wide range of industries to remain competitive in a fast-paced environment. APIs also offer the ability to share data with customers or external users without compromising security. This provides an important foundation for monetizing data. In building operations, APIs can be used to enable automation systems, energy management systems, security systems and other technical equipment to communicate with each other and exchange data. With the aedifion software solution and artificial intelligence, building technology systems are efficiently optimized from the cloud. All data in the building is made available plug-and-play, external data is securely integrated via the API. This ensures a secure and sustainable optimization of your buildings for you.
