Creating Payment Card Programs using Marqeta API in JavaScript

We live in a digital world now, and the ubiquitous availability of the high-speed Internet has transformed many fields; online payment processing is one of them. One of the leading providers in this domain is Marqeta, which allows businesses to issue and process card payments. In this course, we’ll focus on Marqeta API and its services.

## What's an API?
An **API** is a software gateway that allows different software components to communicate with each other. An API helps expose the capabilities of an application to the outer world, allowing for programmatic access to its data.
Consider the case of an application service like Marqeta that provides e-payment solutions. Building and exposing an API for this service will allow others to programmatically fetch the data this service offers, such as accessing information about the user's cards and transactions.

## Prerequisites
This course requires a basic understanding of APIs and fundamental knowledge of JavaScript and React.

This course is designed for anyone who wants to explore and integrate payment card systems and their functionalities. It’ll provide an understanding of Marqeta’s Core API’s various endpoints with some hands-on examples.
