This came up in a conversation with a programmer friend of mine, and he tried to explain it, but he did so badly (to be generous lol). I understand that it’s what apps/users do to use an application, but it’s not clear. Please explain what an API Call is, and what it does. Thanks!
What Is An API Call?
Application Programming Interface, or API, is a software intermediary. Essentially, it delivers your request and delivers the response back to you. It basically acts as a medium for two applications to interact.
An API call is a process that tells an application to communicate.
If you used Sign up with Google on this website you used API call.
When you entered your Google account, the website called Google API and got your information (name, profile picture, etc.), and the website used that information to set up your account – saved you from the hassle of filling in forms and feeding your information again.
