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

Introduction

Hey there, fellow developer! Ready to supercharge your fundraising efforts with Donorbox? Let's dive into building a robust API integration in Java. We'll cover everything you need to know to get up and running quickly.

Prerequisites

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

• A Java development environment (I know you've got this covered!)
• A Donorbox account with API credentials
• Your favorite HTTP client library (we'll use OkHttp in this guide)

Setting up the project

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

1. Create a new Java project in your IDE of choice.
2. Add the OkHttp dependency to your pom.xml:

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

Authentication

Donorbox uses API key authentication. Here's how to set it up:

String apiKey = "your_api_key_here";
String apiToken = "your_api_token_here";

OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(chain -> {
        Request original = chain.request();
        Request request = original.newBuilder()
            .header("Authorization", Credentials.basic(apiKey, apiToken))
            .build();
        return chain.proceed(request);
    })
    .build();

Making API requests

Now, let's make some requests! Here's a quick example to get you started:

Request request = new Request.Builder()
    .url("https://donorbox.org/api/v1/campaigns")
    .build();

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

Implementing key Donorbox API endpoints

Let's implement some crucial endpoints:

Retrieving campaigns

private static void getCampaigns() throws IOException {
    Request request = new Request.Builder()
        .url("https://donorbox.org/api/v1/campaigns")
        .build();

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

Fetching donations

private static void getDonations() throws IOException {
    Request request = new Request.Builder()
        .url("https://donorbox.org/api/v1/donations")
        .build();

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

Creating donors

private static void createDonor(String name, String email) throws IOException {
    RequestBody formBody = new FormBody.Builder()
        .add("donor[name]", name)
        .add("donor[email]", email)
        .build();

    Request request = new Request.Builder()
        .url("https://donorbox.org/api/v1/donors")
        .post(formBody)
        .build();

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

Error handling and best practices

Always handle those pesky errors gracefully:

try {
    // API call here
} catch (IOException e) {
    System.err.println("Error making API call: " + e.getMessage());
    // Log the error, notify the team, etc.
}

Don't forget about rate limiting! Donorbox has limits, so be kind to their servers (and your API quota).

Testing the integration

You know the drill - test, test, test! Here's a quick unit test example:

@Test
public void testGetCampaigns() {
    try {
        getCampaigns();
        // Add assertions here
    } catch (IOException e) {
        fail("Exception thrown: " + e.getMessage());
    }
}

Example use case: Simple donation reporting tool

Let's put it all together with a basic reporting tool:

public static void main(String[] args) {
    try {
        List<Donation> donations = getDonations();
        double totalAmount = donations.stream()
            .mapToDouble(Donation::getAmount)
            .sum();
        System.out.println("Total donations: $" + totalAmount);
    } catch (IOException e) {
        System.err.println("Error generating report: " + e.getMessage());
    }
}

Conclusion

And there you have it! You're now equipped to build a powerful Donorbox API integration in Java. Remember, this is just the tip of the iceberg - there's so much more you can do with the API.
