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.

In this lesson, we'll learn to get a list of all Marqeta cards owned by a specific user. We’ll also learn to get information about a specific card.

# Get all cards owned by a specific user

We can get a list of all Marqeta cards associated with a particular user by making a `GET` request to the `{BASE_URL}/cards/user/{token}` endpoint. The path parameter (`{token}`) refers to the token of the user that we want to retrieve information from. This gives us a list of all the cards associated with that specific user.

This endpoint allows us to filter the visibility of the response fields if necessary. It also supports pagination, which allows us to retrieve a specific range of resources from a complete and sorted list of the returned resources.

Moreover, this endpoint supports object expansion, which lets us optimize API calls and response sizes. It allows us to specify which objects to expand from those returned in the response. For example, as part of the response, this endpoint returns the `token` of the user who owns the card. We can specify if we want to retrieve the complete user object corresponding to the returned `token` as part of the response. This gives us the card object data and the user data with one API call instead of two.

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