Overview

This is a reference application to demonstrate how MBEP APIs can be used. To call these APIs, consumer key and .p12 file required from your project on Mastercard Developers.

Requirements

• Mastercard Developers Account with access to "MBEP" API
• Java 11
• Apache maven 3.3+
• A text Editor or any IDE

Frameworks/Libraries

• Apache Maven
• OpenAPI Generator

Integrating with OpenAPI Generator

OpenAPI Generator generates API client libraries from OpenAPI Specs. It provides generators and library templates for supporting multiple languages and frameworks. Check Generating and Configuring a Mastercard API Client to know more about how to generate a simple API client for consuming APIs.

Generating The API Client Sources

Now that you have all the dependencies you need, you can generate the sources. To do this, use one of the following two methods:

Using IDE

• Method 1
  In IntelliJ IDEA, open the Maven window (View > Tool Windows > Maven). Click the icons Reimport All Maven Projects and Generate Sources and Update Folders for All Projects

• Method 2
  In the same menu, navigate to the commands ({Project name} > Lifecycle), select clean and compile then click the icon Run Maven Build.

Using Terminal

Navigate to the root directory of the project within a terminal window and execute mvn clean compile command.

Configuration

1. Create your account on Mastercard Developers if you don't have it already.
2. Create a new project here and add MBEP to it and click continue.
3. Download Sandbox Signing Key, a .p12 file will be downloaded.
4. In the Client Encryption Keys section of the dashboard, click on the Actions dropdown and download the client encryption key, a ``.pem``` file will be downloaded.
5. Copy the downloaded .p12 and .pem files to src/main/resources folder in your code.
6. Open src/main/resources/application.properties and configure:
   • mastercard.mbep.client.p12.path - Path to keystore (.p12) file, just change the name as per the downloaded file in step 5.
   • mastercard.mbep.client.ref.app.consumer.key - Copy the Consumer key from "Sandbox/Production Keys" section on your project page
   • mastercard.mbep.client.ref.app.keystore.alias - Alias of your key. Default key alias for the sandbox is keyalias.
   • mastercard.mbep.client.ref.app.keystore.password - Password of your Keystore. Default keystore password for sandbox project is keystorepassword.
   • mastercard.mbep.client.ref.app.encryption.file - Path to encryption key (.pem) file, just change the name as per the downloaded file in step 5, e.g. src/main/resources/<fileName>.pem.

Use-Cases

1. Get Benefits Endpoint: "/benefits". Used to get benefits of the user.

2. Check Eligibility
   Endpoint: "/eligibility". Used to check eligibility of a credit card in mbep program for a specific benefit.

3. Create Redemptions
   Endpoint: "/redemptions". Used to create a redemption for a credit card that was previously enrolled through the eligibilities resource.

4. Store Payment Tokens Endpoint: "/payment-tokens". Used to store Pan data as tokens by PSP on behalf of merchants.

More details can be found here.

Execute the Use-Cases

Below are the APIs exposed by this application: - GET /benefits - POST /eligibility
- POST /redemptions
- POST /payment-tokens Once you have added the correct properties, you are ready to build the application. You can do this by navigating to the project’s base directory from the terminal and then by running the following command. mvn clean install

NOTE: - if you want to consume api on production environment please change the url values of mastercard.mbep.client.api.base.path in application.properties, VALUE_BASE_URL in RequestHelperTest.java and VALUE_BASE_URL in MBEPServiceImplTest.java to 'https://api.mastercard.com/elevate'

When the project builds successfully, you can run the following command to start the project

• Run java -jar target/elevate-accelerator-1.0.0.jar command to run the application.
• Open the browser and enter the url http://localhost:8080/mbep/ and you will land on benefits page.
• Click on benefits, tokens, eligibility or redemeptions tab and enter the details as required.
• When submitted you will get JSON response for each service.

NOTE:
- Update request with valid details in json files under location /src/main/resources/templates/ in order to execute these apis successfully.
- For each new call, you should change the email address,such as, dane+101@ifonly.com or dane+102@ifonly.com. If you use the same email address, you may get an error that the benefit has already been redeemed (this is expected). For each new call, you should change the card number. Use the number generator to generate a number that passes the MOD10/Luhn test. The range of eligible PANs is 5555555555550000 through 5555555555559999.
