Introduction

Hey there, fellow developer! Ready to supercharge your email marketing game with Sendinblue? You're in the right place. We're going to walk through building a Sendinblue API integration in Java. It's easier than you might think, and by the end of this guide, you'll be sending emails like a pro.

Prerequisites

Before we dive in, make sure you've got:

  • A Java development environment (I know you've got this covered)
  • A Sendinblue account and API key (if you don't have one, grab it real quick)

Setting up the project

First things first, let's get our project set up:

  1. Add the Sendinblue Java library to your project. If you're using Maven, pop this into your pom.xml:

    <dependency> <groupId>com.sendinblue</groupId> <artifactId>sib-api-v3-sdk</artifactId> <version>6.0.0</version> </dependency>
  2. Initialize the API client in your code:

    ApiClient defaultClient = Configuration.getDefaultApiClient();

Authentication

Time to authenticate! It's as simple as:

ApiKeyAuth apiKey = (ApiKeyAuth) defaultClient.getAuthentication("api-key"); apiKey.setApiKey("YOUR_API_KEY");

Replace "YOUR_API_KEY" with your actual Sendinblue API key. Easy peasy!

Basic API operations

Now for the fun part - let's start using the API:

Sending a transactional email

TransactionalEmailsApi api = new TransactionalEmailsApi(); SendSmtpEmail email = new SendSmtpEmail(); email.setSubject("Hello from Sendinblue!"); email.setHtmlContent("<html><body><h1>This is a test email</h1></body></html>"); email.setTo(Arrays.asList(new SendSmtpEmailTo().setEmail("[email protected]"))); email.setFrom(new SendSmtpEmailFrom().setEmail("[email protected]")); try { CreateSmtpEmail result = api.sendTransacEmail(email); System.out.println(result); } catch (ApiException e) { System.err.println("Exception when calling TransactionalEmailsApi#sendTransacEmail"); e.printStackTrace(); }

Creating a contact

ContactsApi contactsApi = new ContactsApi(); CreateContact contact = new CreateContact(); contact.setEmail("[email protected]"); contact.setAttributes(new HashMap<String, Object>() {{ put("FIRSTNAME", "John"); put("LASTNAME", "Doe"); }}); try { CreateUpdateContactModel result = contactsApi.createContact(contact); System.out.println(result); } catch (ApiException e) { System.err.println("Exception when calling ContactsApi#createContact"); e.printStackTrace(); }

Advanced features

Ready to level up? Let's look at some advanced features:

Scheduling campaigns

EmailCampaignsApi campaignsApi = new EmailCampaignsApi(); CreateEmailCampaign campaign = new CreateEmailCampaign(); // Set up your campaign details here campaign.setScheduledAt(OffsetDateTime.now().plusDays(1)); try { CreateModel result = campaignsApi.createEmailCampaign(campaign); System.out.println(result); } catch (ApiException e) { System.err.println("Exception when calling EmailCampaignsApi#createEmailCampaign"); e.printStackTrace(); }

Error handling and best practices

Always wrap your API calls in try-catch blocks to handle exceptions gracefully. And hey, don't forget about rate limits! Sendinblue has them, so be nice to their servers.

Testing the integration

You're a pro, so I know you're going to write tests. Here's a quick example using JUnit:

@Test public void testSendEmail() { // Set up your test email here CreateSmtpEmail result = api.sendTransacEmail(email); assertNotNull(result); assertEquals("success", result.getMessageId()); }

Deployment considerations

When you're ready to deploy, remember:

  • Use environment variables for your API keys. Never hardcode them!
  • Set up proper logging and monitoring. You'll thank yourself later.

Conclusion

And there you have it! You've just built a Sendinblue API integration in Java. Pretty cool, right? Remember, this is just scratching the surface. There's a whole world of email marketing automation waiting for you to explore.
