Integrating with SDK

Here we have shared code samples to call SearchItems and GetItems operations using PAAPI SDK.

Java

In this section, we will share a simple Java program to create and send request for SearchItems and GetItems operations.

  • Create a simple Java project in your preferred IDE.
  • To get dependencies download zip file, extract contents and add them to your project's build path.
  • Download Java sample code snippets for each operation for Java SDK.
