Newsletter2Go model based API integration

This package provides a model based implementation of the Newsletter2Go API. It aims to make complex documentations unnecessary. With its clear structure and extensive PHPDoc, it is really easy to use.

Install

Via Composer

$ composer require richardhj/newsletter2go-api

Usage

Fetch and alter

If you want to fetch items via the API there might be a static function for. Example:

$users = Richardhj\Newsletter2Go\Api\Model\NewsletterUser::findAll(null, $apiCredentials);

// Use a PHPDoc comment and profit from auto suggestion
/** @var NewsletterUser $user */
foreach ($users as $user) {
    // What's about naming all users "Doe"?
    $user->setLastName('Doe');
    // Save the user (via the API of course)
    $user->save();
    
    // $data contains all data fetched for this item
    $data = $user->getData();
}

$recipients = Richardhj\Newsletter2Go\Api\Model\NewsletterRecipient::findByListAndGroup('abc123', 'xyz987', null, $apiCredentials);
var_dump($recipients);

foreach ($recipients as $recipient) {
    $recipient->addToGroup('xyz345');
    $recipient->removeFromGroup('asdf12');
}

Api Credentials

ApiCredentials are mandatory for the api communication. First of all you need the auth_key that can be found in the Newsletter2Go back end. The auth_key is the same for all company's accounts. Furthermore you either need a user's username and password or a user's refresh_token.

If you rather want to use and save the refresh_token instead of username and password in your application, you have to make an initial api authorization call with the username and password anyway. Check the manual of the corresponding OAuth provider to get to know how to fetch a refresh_token.

// Use the ApiCredentialsFactory
$apiCredentials = ApiCredentialsFactory::createFromUsernameAndPassword('secret_auth_token', 'user@example.org', 'open_sesame');
$apiCredentials = ApiCredentialsFactory::createFromRefreshToken('secret_auth_token', 'secret_users_refresh_token');
// Or simply use ::create()
$apiCredentials = ApiCredentialsFactory::create('secret_auth_token', 'secret_users_refresh_token');

Get parameters

When fetching a collection from the api, you can provide a GetParamters instance. Get parameters allow you to filter, limit etc. the item collection that will be returned. Example:

$getParams = new Richardhj\Newsletter2Go\Api\Tool\GetParameters();
$getParams
    ->setExpand(true)
    ->setFilter('email=like="%@example.org"')
    ->setOffset(2)
    ->setLimit(1);

$recipients = Richardhj\Newsletter2Go\Api\Model\NewsletterRecipient::findByListAndGroup('abc123', 'xyz987', $getParams, $apiCredentials);
var_dump($recipients);

Create

If you want to create items via the API, this is how. Example:

$recipient = new Richardhj\Newsletter2Go\Api\Model\NewsletterRecipient();
$recipient->setApiCredentials($apiCredentials);
$recipient
    ->setListId('abc123')
    ->setFirstName('John')
    ->setLastName('Doe')
    ->setEmail('doe@example.org')
    ->setGender('m');

// Good to have an id, otherwise the email address will be the primary key and you will not be able to change the email address of a recipient properly
$recipient->setId('xyz123');

// Update an existing recipient (when id given or email address known in Newsletter2Go) or create a new recipient
$recipient->save();

Delete

For models that implement Newsletter2Go\Api\Model\ModelDeletableInterface, delete() is available. Example:

$groups = Newsletter2Go\Api\Model\NewsletterGroup::findByList('abc123', $getParams, $credentials);

/** @var NewsletterGroup $group */
foreach ($groups as $group) {
    $group->delete();
}
