hyraiq/abnlookup

A PHP SDK to validate Australian Business Numbers (ABNs) and verify them with the Australian Business Register Web Services API. The difference between validation and verification can be outlined as follows:

• Validation uses the official checksum calculation to check that a given number is a valid ABN. This does not contact the ABR to ensure that the given ABN is assigned to a business
• Verification contact the ABR through their API to retrieve information registered against the ABN. It will tell you if the ABN actually belongs to a business.

In order to use the API (only necessary for verification), you'll need to register an account to receive a GUID which is used as an API key. Once you register you can play with the API using the official demo (note that this SDK uses the JSON services instead of XML).

Type safety

The SDK utilises the Symfony Serializer and the Symfony Validator to deserialize and validate data returned from the ABR API in order to provide valid AbnResponse and NamesResponse models. This means that if you receive a response from the SDK, it is guaranteed to be valid.

Invalid responses from the ABR fall into three categories, which are handled with exceptions:

• AbrConnectionException: Unable to connect to the ABR, or the ABR returned an unexpected response
• InvalidAbnException: The ABN is invalid (ie. validation failed)
• AbnNotFoundException: The ABN is valid, however it is not assigned to a business (ie. verification failed)

Usage

Installation

$ composer require hyraiq/abnlookup

Configuration with Symfony

In services.yaml, you need to pass you ABR GUID to the AbnClient and register the AbnClient with the AbnClientInterface:

Hyra\AbnLookup\AbnClientInterface: '@Hyra\AbnLookup\AbnClient'
Hyra\AbnLookup\AbnClient:
    arguments:
        $abnLookupGuid: "%env(ABN_LOOKUP_GUID)%"

You can then inject the AbnClientInterface directly into your controllers/services.

class VerifyAbnController extends AbtractController
{
    public function __construct(
        private AbnClientInterface $abnClient,
    ) {
    }
    
    // ...  
}

Configuration outside of Symfony

If you're not using Symfony, you'll need to instantiate the ABN client yourself, which can be registered in your service container or just used directly. We have provided some helpers in the Dependencies class in order to create the Symfony Serializer and Validator with minimal options.

use Hyra\AbnLookup\Dependencies;
use Hyra\AbnLookup\AbnClient;

$abrGuid = '<insert your ABR GUID here>'

// Whichever http client you choose
$httpClient = new HttpClient();

$denormalizer = Dependencies::serializer();
$validator = Dependencies::validator();

$abnClient = new AbnClient($denormalizer, $validator, $httpClient, $abrGuid);

Looking up an ABN

Once you have configured your AbnClient you can lookup an individual ABN. Note, this will validate the ABN before calling the API in order to prevent unnecessary API requests.

$abn = '12620650553';

try {
    $abnResponse = $abnClient->lookupAbn($abn);
} catch (AbrConnectionException $e) {
    die($e->getMessage())
} catch (InvalidAbnException) {
    die('Invalid ABN');
} catch (AbnNotFoundException) {
    die('ABN not found');
}

echo $abnResponse->abn; // 12620650553
echo $abnResponse->entityName; // Blenktech PTY LTD
echo $abnResponse->status; // Active

Searching by name

You can also search the ABR by name, to receive a list of registered businesses that match the search term:

$namesResponse = $abnClient->lookupName('Hyra iQ');

echo \sprintf('Received %d results', \count($namesResponse->names));
foreach ($namesResponse->names as $name) {
    echo \sprintf('%s: %s', $name->abn, $name->name);
}

Testing

In automated tests, you can replace the AbnClient with the StubAbnClient in order to mock responses from the ABR. There is also the AbnFaker which you can use during tests to get both valid and invalid ABNs.

use Hyra\AbnLookup\Stubs\AbnFaker;
use Hyra\AbnLookup\Stubs\StubAbnClient;

$stubClient = new StubAbnClient();

$stubClient->lookupAbn(AbnFaker::invalidAbn()); // InvalidAbnException - Note, the stub still uses the validator

$stubClient->lookupAbn(AbnFaker::validAbn()); // LogicException - You need to tell the stub how to respond to specific queries

$abn = AbnFaker::validAbn();
$stubClient->addNotFoundAbns($abn);
$stubClient->lookupAbn($abn); // AbnNotFoundException

$abn = AbnFaker::validAbn();
$mockResponse = new AbnResponse();
$response->abn = $abn;
$response->abnStatus = 'active';
$response->abnStatusEffectiveFrom = new \DateTimeImmutable('2 years ago');
$response->entityTypeCode = 'PRV';
$response->entityTypeName = 'Australian Private Company';

$stubClient->addMockResponse($mockResponse);
$abnResponse = $stubClient->lookupAbn($abn); // $abnResponse === $mockResponse
