Quick Start

Follow these few simple steps to add Mailtrap API functionality into your Java project.

Prerequisites

Make sure your project uses JDK 11 or higher.

Setup

1. Add the library as a Maven/Gradle dependency

Maven dependency:

<dependency>
    <groupId>io.mailtrap</groupId>
    <artifactId>mailtrap-java</artifactId>
    <version>1.0.0</version>
</dependency>

Gradle Groovy dependency:

implementation 'io.mailtrap:mailtrap-java:1.0.0'

Gradle Kotlin DSL dependency:

implementation("io.mailtrap:mailtrap-java:1.0.0")

2. Authentication

• Register/login into Mailtrap
• Obtain an API token with respective permissions and access level to configure and use MailtrapClient.

3. Configuration and usage

import io.mailtrap.client.MailtrapClient;
import io.mailtrap.config.MailtrapConfig;
import io.mailtrap.factory.MailtrapClientFactory;
import io.mailtrap.model.request.emails.Address;
import io.mailtrap.model.request.emails.MailtrapMail;

import java.util.List;

public class Minimal {

    private static final String TOKEN = "<YOUR MAILTRAP TOKEN>";
    private static final String SENDER_EMAIL = "sender@domain.com";
    private static final String RECIPIENT_EMAIL = "recipient@domain.com";

    public static void main(String[] args) {
        final MailtrapConfig config = new MailtrapConfig.Builder()
                .token(TOKEN)
                .build();

        final MailtrapClient client = MailtrapClientFactory.createMailtrapClient(config);

        final MailtrapMail mail = MailtrapMail.builder()
                .from(new Address(SENDER_EMAIL))
                .to(List.of(new Address(RECIPIENT_EMAIL)))
                .subject("Hello from Mailtrap Sending!")
                .text("Welcome to Mailtrap!")
                .build();

        try {
            System.out.println(client.send(mail));
        } catch (Exception e) {
            System.out.println("Caught exception : " + e);
        }
    }
}
