Choose your installation method - Maven w/ Gradle (recommended) or Jar file.

... dependencies { ... compile 'com.sendgrid:smtpapi-java:1.3.3' } repositories { mavenCentral() } ...

Then import the library - in the file appropriate to your Java project.

import com.sendgrid.smtpapi.SMTPAPI;

You can just drop the jar file in. It's a fat jar - it has all the dependencies built in.

smtpapi-java.jar

Update the development environment with your SENDGRID_API_KEY, for example:

echo "export SENDGRID_API_KEY='YOUR_API_KEY'" > sendgrid.env echo "sendgrid.env" >> .gitignore source ./sendgrid.env

• See pom.xml.

import com.sendgrid.smtpapi.SMTPAPI; public class Example { public static void main(String[] args) { SMTPAPI header = new SMTPAPI(); header.addTo("test@example.com"); String headers = header.jsonString(); System.out.println(headers); } }
