A simple implementation of the Bitly link shortening (Bitlinks) API v4.

Examples (TL;DR)

val bitly = Bitly(/* "YOUR_API_ACCESS_TOKEN from https://bitly.is/accesstoken" */)

// Shorten
bitly.bitlinks().shorten("https://erik.thauvin.net/blog")

// Expand
bitly.bitlinks().expand("https://bit.ly/380ojFd")

// Clicks Summary
bitly.bitlinks().clicks("https://bit.ly/380ojFd")

// Create a bitlink
bitly.bitlinks().create(title="Erik's Weblog", long_url = "https://erik.thauvin.net/blog/")

// Update a bitlink
bitly.bitlinks().update("https://bit.ly/380ojFd", title = "Erik's Weblog", tags = arrayOf("blog", "weblog"))

• View bld or Gradle Examples.

API Access Token

The Bitly API Access Token can be specified directly as well as via the BITLY_ACCESS_TOKEN environment variable or properties key.

// Env Variable or System Property
val bitly = Bitly()

// Properties file path
val bitly = Bitly(File("my.properties"))

# my.properties
BITLY_ACCESS_TOKEN=abc123def456ghi789jkl0

bld

To use with bld, include the following dependency in your build file:

repositories = List.of(MAVEN_CENTRAL, SONATYPE_SNAPSHOTS_LEGACY);

scope(compile)
    .include(dependency("net.thauvin.erik:bitly-shorten:1.0.1"));

Be sure to use the bld Kotlin extension in your project.

Gradle, Maven, etc…

To use with Gradle, include the following dependency in your build file:

repositories {
    mavenCentral()
    maven { url = uri("https://oss.sonatype.org/content/repositories/snapshots") } // only needed for SNAPSHOT
}

dependencies {
    implementation("net.thauvin.erik:bitly-shorten:1.0.1")
}

Instructions for using with Maven, Ivy, etc. can be found on Maven Central.

Java

To make it easier to use the library with Java, configuration builders are available:

var config = new CreateConfig.Builder()
        .title("Erik's Weblog")
        .tags(new String[] { "blog", "weblog"})
        .longUrl("https://erik.thauvin.net/blog")
        .build();

bitly.bitlinks().create(config);

var config = new UpdateConfig.Builder()
        .bitlink("https://bit.ly/380ojFd")
        .title("Erik's Weblog")
        .tags(new String[] { "blog", "weblog"})
        .build();

bitly.bitlinks().update(config);

JSON

All implemented API calls can return the full JSON responses:

bitly.bitlinks().shorten("https://www.erik.thauvin.net/blog", toJson = true)

{
    "created_at": "2020-02-26T06:50:08+0000",
    "link": "https://bit.ly/380ojFd",
    "id": "bit.ly/380ojFd",
    "long_url": "https://erik.thauvin.net/blog"
}

API Response & Endpoints

You can also access the last response from implemented API calls using:

val bitlinks = Bitlinks(apikey)
val shortUrl = bitlinks.shorten(longUrl)
val response = bitlinks.lastCallResponse

if (response.isSuccessful) {
    println(response.body)
} else {
    println("${response.message}: ${response.description} (${response.statusCode})")
}

Non-implemented API endpoints can also be called directly:

val response = bitly.call("/user", method = Methods.GET)
if (response.isSuccessful) {
    println(response.body)
}

{
    "created": "2009-06-12T19:00:45+0000",
    "modified": "2016-11-11T19:50:33+0000",
    "login": "johndoe",
    "is_active": true,
    "is_2fa_enabled": true,
    "name": "John Doe",
    "emails": [
        {
            "email": "john@doe.com",
            "is_primary": true,
            "is_verified": true
        }
    ],
    "is_sso_user": false,
    "default_group_guid": "ABCde1f23gh"
}
