1. Getting the SDK

In order to use Express Checkout SDK, the very first step is to install the SDK into your application with proper configurations. This has two steps to it:

1. Installing Assets Plugin

2. Installing Express Checkout SDK

Following sections describe how to complete the steps above -

1.1. Installing Assets Plugin

The SDK depends on certain assets/files to function. These are available over the air and are supposed to be present while building the SDK.
The Assets Plugin is a build time dependency that downloads all required assets and ensures the availability of the latest assets at build time.

To install Assets Plugin follow the below steps

Step 1.1a

Add Assets Plugin maven url

Copy Code

The maven URL specifies from where the assets plugin should be downloaded. This is supposed to present inside the buildscript of your application

Step 1.1b

Add Assets plugin classpath

Copy Code

Adding classpath to buildscript dependencies helps build tool load the assets plugin. This also resides inside buildscript.

Step 1.1c

Apply Assets plugin

Copy Code

This step will ensure that assets plugin is used as a plugin inside your application build cycle. Ensure you apply the plugin inside your app/build.gradle

1.2. Installing Express Checkout SDK

For using the services provided by Express Checkout SDK, client needs to implement certain APIs exposed by the SDK. The SDK is a build time dependency which exposes certain classes for use across your application.

To install Express Checkout SDK follow the below steps

Step 1.2.a

Add SDK maven url

Copy Code

The maven url specifies from where the SDK dependency should be downloaded. It should be present inside the allProjects/repositories section of your project build.gradle

Warning

Make sure it is added to project dependency section. (eg: build.gradle (Project:ProjectName))

Step 1.2.b

Add SDK implementation

Copy Code

To inject SDK as dependency in your application, include it in your application build.gradle dependencies

After adding Assets Plugin and Hyper SDK to your project, please ensure you do a gradle sync and clean build
