There are many different types of requests that API could handle, but here are the most used ones: Metaphorically, it’s like a conversation between two people: Someone (you) asks a question (request), and the interlocutor (endpoint) answers (response). Furthermore, APIs should have documentation that explains all endpoints, types of returned values, etc.Īfter you find an interesting API and read documentation, you have to send a request – one single task for the server (receiving side). How does this interface work?įirst and foremost, an API should have a host-URL (or base URL), which is the main address with which you will interact with.Īlso, APIs has a predefined set of endpoints – unique addresses inside host-URL, responsible for their functionality. APIs allows us to skip diving deeply in the source code of some third-side software while allowing us to use their privileges fast and easy. In short, it’s a set of rules that controls the interaction between software (i.e., an object that receives some task and object that gives this task). Well, API stands for Application Programming Interface.
