What are APIs?

This allows for services and products to communicate their data and function in a well-documented way. As of recent API has had a surge in use as of recent, mainly because most developers can focus on conversing with other services and products.


How do developers use APIs?

Well as mentioned before Developers use APIs to share information, however, this is automated. An API uses a set of rules that detail how it communicates with other computers and applications. This usually has a four-step process –

  1. A client initiates a request
  2. The API communicates with an external program or a web browser
  3. The server sends a response to the API
  4. The API sends the data to the client

This process is secure and trusted. The API always verifies if the client is an authorized person. The API always comes through, since it never needs a human-like response time. To clarify A API is solely run by a computer, however, it communicates differently with other web services
