Marqeta React App

Marqeta is a modern card issuing and transaction processing platform that streamlines business payments by working with card networks and issuing banks to issue cards, authorize transactions, and communicate with settlement entities.

In this course, you will learn about Marqeta’s Core API, its resources, and the relationships among them. Next, you will get to learn how to create and manage these resources and their relevant functionalities. Then, you will learn how to simulate transactions and their reversals in a sandbox test environment using a Marqeta payment card. In addition to this, you will also learn how to create a simple application using the Marqeta API integration. Finally, this course will provide some recommendations and resources for further exploration of Marqeta’s Core API and its integration.

After completing this course, you will be able to create a simple application with the Marqeta API integration and be able to implement a majority of its functionality.

Creating Payment Card Programs using Marqeta API in JavaScript

A **card product** defines the behavior and functionality of Marqeta cards. It defines the card's attributes and provides information regarding its usage. It also allows us to specify the specific channels where cards can be used, for example, at ATMs, points of sale (POS), and e-commerce websites.

In addition to the card product object, we can also define the attributes in the card object. If we end up with multiple definitions, the definition in the card object will take precedence over the definition in the card product object.

In this lesson, we’ll learn to create and update a card product.

## Create a card product 

We can create a card product by making a `POST` request to the `{BASE_URL}/cardproducts` endpoint. We can provide basic information about the card product in the request's body. We can also provide configuration information using the `config` object. This information defines the features and the behavior of the card product.

### Request parameters
The request parameters of the endpoint are provided in the table below:
