Changelog

September 5, 2025

Updated all Java examples to use the new addHeader method for adding authentication headers, simplifying how Sandbox authentication headers are set in Java applications.

Java SDK Improvements

The Lattice SDK for Java 2.3.0 introduces a simplified approach for adding authentication headers to API requests:

  • Added new addHeader method to the Lattice client builder that eliminates the need to create custom OkHttpClient instances.
  • Updated all Java examples to use this new approach, resulting in cleaner, more maintainable code.
  • Removed boilerplate OkHttpClient interceptor configuration that was previously required.
