Twinfield

A PHP library for Twinfield Integration. Use the Twinfield SOAP Services to have your PHP application communicate directly with your Twinfield account.

:warning: Note that this library is not created or maintained by Twinfield. You can only get support on the code in this library here. For any questions related to your Twinfield administration or how to do certain things with the Twinfield API, contact your Twinfield account manager.

Installation

Install this Twinfield PHP library with Composer:

composer require 'php-twinfield/twinfield:^3.0'

Usage

Authentication

You need to set up a \PhpTwinfield\Secure\AuthenticatedConnection class with your credentials. When using basic username and password authentication, the \PhpTwinfield\Secure\WebservicesAuthentication class should be used, as follows:

Username and password

$connection = new Secure\WebservicesAuthentication("username", "password", "organization");

Some endpoints allow you to filter on the Office, but for instance the BrowseData endpoint doesn't. For this you need to switch to the correct office before making the request, you can do this after authentication like so:

$office = Office::fromCode("someOfficeCode");
$officeApi = new \PhpTwinfield\ApiConnectors\OfficeApiConnector($connection);
$officeApi->setOffice($office);

oAuth2

In order to use OAuth2 to authenticate with Twinfield, one should use the \PhpTwinfield\Secure\Provider\OAuthProvider to retrieve an \League\OAuth2\Client\Token\AccessToken object, and extract the refresh token from this object. Furthermore, it is required to set up a default \PhpTwinfield\Office, that will be used during requests to Twinfield. Please note: when a different office is specified when sending a request through one of the ApiConnectors, this Office will override the default.

Using this information, we can create an instance of the \PhpTwinfield\Secure\OpenIdConnectAuthentication class, as follows:

$provider    = new OAuthProvider([
    'clientId'     => 'someClientId',
    'clientSecret' => 'someClientSecret',
    'redirectUri'  => 'https://example.org/'
]);
$accessToken  = $provider->getAccessToken("authorization_code", ["code" => ...]);
$refreshToken = $accessToken->getRefreshToken();
$office       = \PhpTwinfield\Office::fromCode("someOfficeCode");

$connection  = new \PhpTwinfield\Secure\OpenIdConnectAuthentication($provider, $refreshToken, $office);

In the case you have an existing accessToken object you may pass that to the constructor or set it, to limit the amount of access token and validate requests, since the accessToken is valid for 1 hour.

$provider    = new OAuthProvider([
    'clientId'     => 'someClientId',
    'clientSecret' => 'someClientSecret',
    'redirectUri'  => 'https://example.org/'
]);
$accessToken  = $provider->getAccessToken("authorization_code", ["code" => ...]);
$refreshToken = $accessToken->getRefreshToken();
$office       = \PhpTwinfield\Office::fromCode("someOfficeCode");

$connection  = new \PhpTwinfield\Secure\OpenIdConnectAuthentication($provider, $refreshToken, $office, $accessToken);

or

$connection = new \PhpTwinfield\Secure\OpenIdConnectAuthentication($provider, $refreshToken, $office);
$connection->setAccessToken($accessToken);

Setting an access token will force a new validation request on every login.

It's also possible to provide callables, that will be called when a new access token is validated. This way you're able to store the new 'validated' access token object and your application can re-use the token within an hour. This way you can optimize the number of requests.

Be aware to store your access token in an appropriate and secure way. E.g. encrypting it.

$connection = new \PhpTwinfield\Secure\OpenIdConnectAuthentication($provider, $refreshToken, $office, $accessToken);
$connection->registerAfterValidateCallback(
    function(\League\OAuth2\Client\Token\AccessTokenInterface $accessToken) {
        // Store the access token.
    }
);

For more information about retrieving the initial AccessToken, please refer to: https://github.com/thephpleague/oauth2-client#usage

Getting data from the API

In order to communicate with the Twinfield API, you need to create an ApiConnector instance for the corresponding resource and use the get() or list() method.

The ApiConnector takes a Secure\AuthenticatedConnection object:

An example:

$connection = new Secure\WebservicesAuthentication("username", "password", "organization");
$customerApiConnector = new ApiConnectors\CustomerApiConnector($connection);

// Get one customer.
$office   = Office::fromCode('office code');
$customer = $customerApiConnector->get('1001', $office);

// Get a list of all customers.
$customer = $customerApiConnector->listAll($office);

Creating or updating objects

If you want to create or update a customer or any other object, it's just as easy:

$customer_factory = new ApiConnectors\CustomerApiConnector($connection);

// First, create the objects you want to send.
$customer = new Customer();
$customer
    ->setCode('1001')
    ->setName('John Doe')
    ->setOffice($office)
    ->setEBilling(false);

$customer_address = new CustomerAddress();
$customer_address
    ->setType('invoice')
    ->setDefault(false)
    ->setPostcode('1212 AB')
    ->setCity('TestCity')
    ->setCountry('NL')
    ->setTelephone('010-12345')
    ->setFax('010-1234')
    ->setEmail('johndoe@example.com');
$customer->addAddress($customer_address);

// And secondly, send it to Twinfield.
$customer_factory->send($customer);

You can also send multiple objects in one batch, chunking is handled automatically.

Browse data

In order to get financial data out of Twinfield like general ledger transactions, sales invoices, and so on, you can use the the browse data functionality. More information about the browse data functionality in Twinfield can be found in the documentation.

Browse definition

You can retrieve the browse definition of a browse code as follows. You don't need to retrieve the browse definition for getting the browse data. It's only for viewing the browse definition of a browse code to know exactly which columns are available.

$connector = new BrowseDataApiConnector($connection);
$browseDefinition = $connector->getBrowseDefinition('000');

Browse fields

You can retrieve the browse fields as follows. You don't need to retrieve the browse fields for getting the browse data. It's only for viewing the definitions of all browse fields so you now what you can expect when retrieving browse data.

$connector = new BrowseDataApiConnector($connection);
$browseFields = $connector->getBrowseFields();

Browse data

You can retrieve browse data of a browse code as follows.

$connector = new BrowseDataApiConnector($connection);

// First, create the columns that you want to retrieve (see the browse definition for which columns are available)
$columns[] = (new BrowseColumn())
    ->setField('fin.trs.head.yearperiod')
    ->setLabel('Period')
    ->setVisible(true)
    ->setAsk(true)
    ->setOperator(Enums\BrowseColumnOperator::BETWEEN())
    ->setFrom('2013/01')
    ->setTo('2013/12');

$columns[] = (new BrowseColumn())
    ->setField('fin.trs.head.code')
    ->setLabel('Transaction type')
    ->setVisible(true);

$columns[] = (new BrowseColumn())
    ->setField('fin.trs.head.shortname')
    ->setLabel('Name')
    ->setVisible(true);

$columns[] = (new BrowseColumn())
    ->setField('fin.trs.head.number')
    ->setLabel('Trans. no.')
    ->setVisible(true);

$columns[] = (new BrowseColumn())
    ->setField('fin.trs.line.dim1')
    ->setLabel('General ledger')
    ->setVisible(true)
    ->setAsk(true)
    ->setOperator(Enums\BrowseColumnOperator::BETWEEN())
    ->setFrom('1300')
    ->setTo('1300');

$columns[] = (new BrowseColumn())
    ->setField('fin.trs.head.curcode')
    ->setLabel('Currency')
    ->setVisible(true);

$columns[] = (new BrowseColumn())
    ->setField('fin.trs.line.valuesigned')
    ->setLabel('Value')
    ->setVisible(true);

$columns[] = (new BrowseColumn())
    ->setField('fin.trs.line.description')
    ->setLabel('Description')
    ->setVisible(true);

// Second, create sort fields
$sortFields[] = new BrowseSortField('fin.trs.head.code');

// Get the browse data
$browseData = $connector->getBrowseData('000', $columns, $sortFields);

ApiConnector Configuration

The ApiConnector has a constructor second parameter that can be used to configure some aspects of its operation.

The ApiOptions has the following methods signature:

/**
 * This will allow you to enfornce the messages or the number of max retries.
 * Passing null you will use the default values.
 */
public function __construct(?array $messages = null, ?int $maxRetries = null);
/**
 * This will allow you to get all the exception messages
 */
public function getRetriableExceptionMessages(): array
/**
 * This will allow you to replace the exception messages that should be retried
 */
public function setRetriableExceptionMessages(array $retriableExceptionMessages): ApiOptions
/**
 * This will allow you to add new messages to the array of exception messages
 */
public function addMessages(array $messages): ApiOptions
/**
 * This will allow you to get the number of max retries
 */
public function getMaxRetries(): int
/**
 * This will allow you to set the number of max retries
 */
public function setMaxRetries(int $maxRetries): ApiOptions

:exclamation: All the get methods will return a new instance with the configuration you changed.

Configuration Examples

Below are some examples on how to use the configuration object

$connector = new BrowseDataApiConnector(
    $connection,
    new ApiOptions(
        [
            "SSL: Connection reset by peer",
            "Bad Gateway"
        ], 
        3
    )
);

The example below will look for the default messages plus the "Bad Gateway" message.

$options = new ApiOptions(
    null, 
    3
);
$connector = new BrowseDataApiConnector(
    $connection,
    $options->addMessages(["Bad Gateway"])
);

Configuration default values
