Step by Step Guide to Building a Duda API Integration in Java

Introduction

Hey there, fellow developer! Ready to dive into the world of Duda API integration? You're in for a treat. Duda's API is a powerhouse for managing websites, and we're about to harness that power with Java. This guide will walk you through creating a robust integration that'll have you manipulating sites, content, and more in no time.

Prerequisites

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

• A Java development environment (I know you've got this covered)
• Duda API credentials (if you don't have these yet, hop over to Duda's developer portal)
• An HTTP client library (we'll be using OkHttp, but feel free to use your favorite)

Setting Up the Project

Let's get the boring stuff out of the way:

1. Create a new Java project in your IDE of choice.
2. Add OkHttp to your dependencies. If you're using Maven, toss this into your pom.xml:

<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>4.10.0</version>
</dependency>

Authentication

Duda uses API key and secret for authentication. Let's set that up:

public class DudaApiClient {
    private final String apiKey;
    private final String apiSecret;
    private final OkHttpClient client;

    public DudaApiClient(String apiKey, String apiSecret) {
        this.apiKey = apiKey;
        this.apiSecret = apiSecret;
        this.client = new OkHttpClient();
    }

    private Request.Builder getAuthenticatedBuilder(String url) {
        return new Request.Builder()
            .url(url)
            .addHeader("Authorization", Credentials.basic(apiKey, apiSecret));
    }
}

Making API Requests

Now for the fun part - let's start making some requests:

public String getSite(String siteName) throws IOException {
    Request request = getAuthenticatedBuilder("https://api.duda.co/api/sites/multiscreen/" + siteName)
        .build();

    try (Response response = client.newCall(request).execute()) {
        if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
        return response.body().string();
    }
}

Implementing Key Duda API Endpoints

Let's add methods for some crucial operations:

public String createSite(String templateId, String siteName) throws IOException {
    RequestBody body = RequestBody.create(
        "{\"template_id\":\"" + templateId + "\",\"default_domain_prefix\":\"" + siteName + "\"}",
        MediaType.get("application/json; charset=utf-8")
    );

    Request request = getAuthenticatedBuilder("https://api.duda.co/api/sites/multiscreen/create")
        .post(body)
        .build();

    try (Response response = client.newCall(request).execute()) {
        if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
        return response.body().string();
    }
}

public String updateContent(String siteName, String contentJson) throws IOException {
    RequestBody body = RequestBody.create(contentJson, MediaType.get("application/json; charset=utf-8"));

    Request request = getAuthenticatedBuilder("https://api.duda.co/api/sites/multiscreen/" + siteName + "/content")
        .post(body)
        .build();

    try (Response response = client.newCall(request).execute()) {
        if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
        return response.body().string();
    }
}

Error Handling and Response Parsing

Let's add some robust error handling:

private String handleResponse(Response response) throws IOException {
    if (!response.isSuccessful()) {
        String errorBody = response.body().string();
        throw new DudaApiException("API request failed: " + response.code() + " " + errorBody);
    }
    return response.body().string();
}

// Use this in your API methods:
try (Response response = client.newCall(request).execute()) {
    return handleResponse(response);
}

Best Practices

Remember to:

• Implement rate limiting to avoid hitting API limits
• Cache responses when appropriate to reduce API calls
• Never expose your API credentials in client-side code

Testing the Integration

Don't forget to test! Here's a quick example:

@Test
public void testGetSite() {
    DudaApiClient client = new DudaApiClient("your-api-key", "your-api-secret");
    String siteInfo = client.getSite("test-site");
    assertNotNull(siteInfo);
    // Add more assertions based on expected response
}

Conclusion

And there you have it! You've just built a solid foundation for integrating with the Duda API. From here, you can expand to cover more endpoints, implement more sophisticated error handling, and build some really cool features.

Remember, the Duda API documentation is your best friend for diving deeper. Now go forth and build something awesome!
