1. Prerequisites

To follow this guide, you will need to:

​
2. Install and initialize the Dub PHP SDK

1

Install

To install the Dub PHP SDK, run the following command:
composer require dub/dub-php
2

Configuration

In your .env file, add your Dub API key:
DUB_API_KEY=your_api_key
In your config/services.php file, add the following:
'dub' => [
  'api_key' => env('DUB_API_KEY'),
],
3

Initialize

You can now create an instance of the Dub class and pass in your API key:
index.php
use Dub\Dub;
use Dub\Components\Security;

$dub = Dub::builder()->setSecurity(config('services.dub.api_key'))->build();

// create a link
$dub->links->create(...);
4

Service Container (Optional)

If you want to be able to inject the Dub class via the service container, add this to the register method of your AppServiceProvider.php:
index.php
$this->app->bind(Dub::class, function ($app) {
  return Dub::builder()->setSecurity($app['config']->get('services.dub.api_key'))->build();
});
You can then inject the authenticated Dub instance throughout your application:
index.php
use Dub\Laravel\Dub;

class LinkController extends Controller {
  public function createLink(Dub $dub) {
    // Now you can use the SDK instance
    $dub->links->create(...);
  }
}
Let’s create a short link using the Dub Laravel SDK.
index.php
use Dub\Models\Operations;

class LinkController extends Controller {
  public function createLink() {
    $dub = new Dub();

    try {
      $request = new Operations\CreateLinkRequestBody(
        url: 'https://google.com'
      );

      $response = $dub->links->create($request);

      if ($response->linkSchema !== null) {
        // handle response
      }
  } catch (Throwable $e) {
    // handle exception
  }
  }
}
Optionally, you can also pass an externalId field to associate the link with a unique identifier in your own system.
index.php
use Dub\Models\Operations;

class LinkController extends Controller
{
    public function createLinkWithExternalId()
    {
        $dub = new Dub();

        try {
            $request = new Operations\CreateLinkRequestBody(
                url: 'https://google.com',
                externalId: '12345'
            );

            $response = $dub->links->create($request);

            if ($response->linkSchema !== null) {
                // handle response
            }
        } catch (Throwable $e) {
            // handle exception
        }
    }
}
This will let you easily update the link or retrieve analytics for it later on using the externalId instead of the Dub linkId. The Dub Laravel SDK provides a method to upsert a link – where an existing link is updated if it exists, or a new link is created if it doesn’t.
index.php
use Dub\Models\Operations;

class LinkController extends Controller
{
    public function upsertLink()
    {
        $dub = new Dub();

        try {
            $request = new Operations\UpsertLinkRequestBody(
                url: 'https://google.com'
            );

            $response = $dub->links->upsert($request);

            if ($response->linkSchema !== null) {
                // handle response
            }
        } catch (Throwable $e) {
            // handle exception
        }
    }
}
This way, you won’t have to worry about checking if the link already exists when you’re creating it. To update an existing link using the Dub Laravel SDK, you can either use the link’s linkId or externalId.
index.php
use Dub\Models\Operations;

class LinkController extends Controller
{
    public function updateLink()
    {
        $dub = new Dub();

        try {
            $request = new Operations\UpdateLinkRequest();
            $request->linkId = 'cly2p8onm000cym8200nfay7l';
            $request->requestBody = new Operations\UpdateLinkRequestBody();
            $request->requestBody->url = 'https://google.us';

            $response = $dub->links->update($request);

            if ($response->linkSchema !== null) {
                echo $response->linkSchema->shortLink;
            }
        } catch (Throwable $e) {
            // handle exception
        }
    }
}
You can also retrieve analytics for a link using the Dub Laravel SDK.
index.php
use Dub\Models\Operations;

class LinkController extends Controller
{
    public function retrieveAnalytics()
    {
        $dub = new Dub();

        try {
            $request = new Operations\RetrieveAnalyticsRequest();
            $request->linkId = 'clmnr6jcc0005l308q9v56uz1';
            $request->interval = Operations\Interval::SevenD;
            $request->groupBy = Operations\GroupBy::Timeseries;

            $response = $dub->analytics->retrieve($request);

            if ($response->oneOf !== null) {
                // Handle the response
                print_r($response->oneOf);
            }
        } catch (Throwable $e) {
            // handle exception
        }
    }
}
