An Application Programming Interface (API) is a set of routines, protocols, and tools for building software applications. A good API makes it easier to develop programs by providing all the building blocks, the programmer then puts the blocks together. Advantech SUSI (Secure & Unified Smart Interface) provides a set of user-friendly API, which speeds development, enhances security, and offers add-on value for Advantech platforms. SUSI plays the role of a catalyst between the developer and solution, which makes Advantech embedded platforms easier and simpler to integrate with the customer’s own applications.
