How does API contribute to application integration?
APIs are a critical part of the application integration process. These are the glue that connects disparate programs so they can exchange data and interoperate. As an application integration engineer, you should have an in-depth knowledge of APIs, how they work, and how you use them in your job. You will always be asked about this by the interviewer, so you should prepare your answer and advance.
"APIs enable interaction between data, applications, and devices. They deliver data and facilitate connectivity between devices and programs. I use APIs extensively in my job as an application integration engineer. The specific APIs I employ are defined by the application the organization uses, their dependencies, how the applications are implemented, and the online programming interface of the organization. If implemented appropriately, APIs will allow the organization's applications to communicate with backend systems, each other, and the IT hardware the company has deployed."
