Marqeta's Core API allows companies to launch and manage their payment card programs.

Django

Marqeta is a modern card issuing and transaction processing platform that allows companies to launch and scale card programs to meet their business needs. It streamlines business payments by working with card networks and issuing banks to issue cards, authorize transactions, and communicate with settlement entities.

In this course, we'll learn about Marqeta's Core API, its resources, and the relationships among them. We'll learn to create and manage these resources and their relevant functionalities. We'll also learn to simulate transactions and their reversals in a sandbox test environment using a Marqeta payment card. Additionally, we'll learn to create a simple application using Marqeta API integration.

Lastly, this course will provide some recommendations and resources for further exploration of Marqeta's Core API and its integration.

Creating Payment Card Programs using Marqeta API in Python

## Overview

In this lesson, we’ll learn how to get a list of all existing card products. We’ll also learn how to get information about a specific card product we choose.

## Endpoints

### Get all card products
We can get a list of all card products by making a `GET` request to the `{BASE_URL}/cardproducts` endpoint. This gives us a list of all existing card products with their details. This endpoint also supports pagination, which allows us to retrieve a specific range of resources from the sorted list of returned resources.

### Get a single card product
Similarly, we can get a single card product by making a `GET` request to the `{BASE_URL}/cardproducts/{token}` endpoint. The path parameter (`{token}`) refers to the token of the card product that we want to retrieve.

## Request parameters

align-center

## Sample codes

> **Note**: You may append any of the optional query parameters in the table above to the `url` in **line 1** to fine-tune your search.

Click the "Run" button in the code widget below to see the list of all card products.

url = '{{BASE_URL}}cardproducts'

response = requests.get(url, headers=headers)

printResponse(response)

**Line 1:** We have the value for `{token}`, which is a required path parameter, that we stored in the previous lesson. However, we may also use any `token` value from the output of the code above.

Click the "Run" button in the code widget below to see the output.

token = '{{CARD_PRODUCT_TOKEN}}'

url = '{{BASE_URL}}cardproducts/' + token

response = requests.get(url, headers=headers)

printResponse(response)

## Output

When the code is successfully executed, the output displays the requested number of card product objects (with their attributes), their total count and other information.

>**Note:** We may see an extra card product with the name `Reloadable Card` as part of the output of the first block of code.

For the second code widget, the output displays the complete card product object that corresponds to the given `token` with all of the requested data fields.

In case of failure, an appropriate error message is displayed.

Parameter	Type	Category	Description
`token`	string	required	Token of the card product we want to retrieve Note: This is a path parameter to get a single card product.
`count`	integer	optional	Number of card products to retrieve Allowable values: 1–10 Note: This is a query parameter to get all card products.
`sort_by`	string	optional	Sorts by the given value Note: By default, the sorting is in ascending order. To sort in descending order, add a hyphen (-) to the field name. This is a query parameter to get all card products.
`start_index`	integer	optional	Sort order index of the first object in the array of returned resources Note: This is a query parameter to get all card products.
