Is there a Restaurant-Com-API


What is an API

Overview of all content

An API (Application Programming Interface) describes a programming interface that is used to create software through communication protocols and tools. In general, it is a set of well-defined communication methods between different components. Good APIs make it easier to develop a computer program by providing all the building blocks that are then put together by programmers.


Is there a simpler definition?

The above explanation is well and good, but in the end it sounds way too technical to the layman. To describe the concept in more detail, you need to understand the basics.

A small example can be used to illustrate this. For example, if you go to a restaurant, you can choose from the choices on the menu. You then convey your decision to the waiter.

This then transmits your selection to the cook, who then prepares the meal. However, in this example you cannot know how exactly your food was prepared. You don't know which ingredients were used or how the food was prepared.

This exemplary analogy serves as a starting point for explaining the API. This is due to the fact that with the API you don't really know what's going on behind the scenes either.


A real-life API example

A practical example would be buying movie tickets online. You go to the film page, search for a film and fill in your details. You can then print out your tickets. But what happens between entering your details and receiving your ticket? In between, APIs are used!

These work behind the scenes with other applications. You may be wondering how this is possible. The transition to the individual programs is seamless so that the user does not notice when one is being passed from one application to another.

In general, APIs define the rules that programmers must follow to interact with a programming language, software library, or other software tool. They are the catalyst for smooth application mobilization. Without it, you are missing the most important component to ensure a smooth process, to ensure technical progress.


Frequently asked questions about APIs

1. What is an API key?

An API key is a piece of code that is transmitted by computer applications. The program or application then calls the API or interface to identify the user, developer, or called program for a website.

API keys are often used to prevent misuse or malicious use of the API in question.

An API key can be used both as a secret authentication token and as a unique means of identification.
Typically, the key has a number of access rights to the API with which it is associated.


2. What is a REST API?

A REST API is based on Representative State Transfer (REST) ​​technology, an architectural style and communication approach commonly used in web development.

REST technology is generally preferred to the more robust Simple Object Access Protocol (SOAP) technology because REST uses less bandwidth and is therefore better suited for Internet use.

An API for a website is code that enables two software programs to communicate with each other. The API describes the right way for a developer to write a program that requests services from an operating system or other application.



An "application program interface" (API) is a series of routines, protocols and tools for creating software applications. Basically, an API specifies how software components should work together. In addition, APIs are used when programming GUI (Graphical User Interface) components.

How does an API work?

An API is a software intermediary that enables two applications to communicate with each other. In other words, an API is the messenger that delivers your request to the provider you're requesting it from and then delivers the answer back to you.

One example is the Apple (iOS) API, which is used to detect touchscreen interactions. APIs are tools. They enable you as a programmer to deliver solid solutions relatively quickly.
