Once you are comfortable with the same and have also explored the documentation to know about the various APIs that Visa exposes, you can then use the Java sample code on this site as a starting point in your journey towards building your application.

Sample code is available for the following capabilities:

• Visa Direct
• Visa Merchant Offers Resource Center

The instructions will guide you make the first call to VDP from your local machine for development and testing purposes.

• Java JDK: (Version 1.8.0 or above)
• Build Tools: Maven (Version 3.0.5 or above)

• Configure the credentials required

Edit the file /Samples/src/main/resources/auth_config.xml to set the fields shown below. Refer the Getting Started Guide to get the credentials.
