The Paubox Java SDK is the official Java client library for the Paubox Email API and Paubox Forms. Add the JAR to your project and send encrypted, HIPAA compliant email with a few lines of Java.

​
Installation

The SDK is not published to Maven Central. The stable-jar-file/Paubox.Email.API.jar committed to the repository is version 1.2 from 2019 and only supports sending a message and checking its disposition, so do not use it. Instead, download the Paubox.Email.API-<version>.jar asset from the latest GitHub release, or build the JAR from source with Maven:
The build writes target/Paubox.Email.API.jar. Add the JAR to your project’s classpath. Eclipse / IntelliJ IDEA: Right-click your project → Build Path / Dependencies → Add External JARs → select Paubox.Email.API.jar. Maven (local JAR):
Apache HttpClient and Jackson are bundled in the JAR; no additional dependencies are required.
