Java SDK

The Java SDK aims to help implement all API calls coming from the airline backend. It will automatically retrieve and renew authentication tokens required to consume the Hopper Cloud Airlines API.

Client initialization

Download

Gradle:

dependencies {
  implementation group: 'com.hopper.cloud', name: 'cloud-airlines-java', version: '1.4.1'
}

Maven:

<!-- https://mvnrepository.com/artifact/com.hopper.cloud/cloud-airlines-java -->
<dependency>
  <groupId>com.hopper.cloud</groupId>
  <artifactId>cloud-airlines-java</artifactId>
  <version>1.4.1</version>
</dependency>

Parameters

  • Endpoint URL: Will be provided by Hopper for each environment
  • Client ID: Will be provided by Hopper for each environment
  • Client Secret: Will be provided by Hopper for each environment
  • Payment Url: Will be provided by Hopper for each environment
  • Payment Username: Will be provided by Hopper for each environment
  • Payment Password: Will be provided by Hopper for each environment
  • Debugging : True to log input and output
HopperClient client = new HopperClient(endpointUrl, clientId, clientSecret, paymentUrl, paymentUsername, paymentPassword, debugging);

Client methods
