Mailchimp

Basic abstraction with Laravel integration for Mailchimp API v3, _(*1)

Installation

composer require nztim/mailchimp
For Laravel support:
- Laravel 5.5+ will auto-discover the package, for earlier versions you will need to:
  - Add the service provider to config/app.php: NZTim\Mailchimp\MailchimpServiceProvider::class,
  - Register the facade: 'Mailchimp' => NZTim\Mailchimp\MailchimpFacade::class,
- Add an .env value for MC_KEY (your API key)
- Optionally, publish the config file:
  - php artisan vendor:publish --provider=NZTim\Mailchimp\MailchimpServiceProvider

Usage

Within Laravel 5, use the Mailchimp facade or inject NZTim\Mailchimp\Mailchimp using the container.
Alternatively, instantiate using the API key: $mc = new NZTim\Mailchimp\Mailchimp($apikey)

// Get an array of all available lists:
Mailchimp::getLists();

// Get lists with parameters - get IDs of lists a user is subscribed to:
Mailchimp::getLists(['email' => 'user@example.com', 'fields' => 'lists.id']);

// Check to see if an email address is subscribed to a list:
Mailchimp::check($listId, $emailAddress); // Returns boolean

// Check the staus of a subscriber:
Mailchimp::status($listId, $emailAddress); // Returns 'subscribed', 'unsubscribed', 'cleaned', 'pending', 'transactional' or 'not found'

// Get subscriber tags:
Mailchimp::getTags($listId, $emailAddress); // Returns array of Tag objects

// Add tags to a subscriber
Mailchimp::addTags($listId, $emailAddress, $tags); // $tags = ['tag1', 'tag2']

// Remove tags from a subscriber
Mailchimp::removeTags($listId, $emailAddress, $tags); // $tags = ['tag1', 'tag2']

// Remove all tags from a subscriber
Mailchimp::removeAllTags($listId, $emailAddress); 

// Adds/updates an existing subscriber:
Mailchimp::subscribe($listId, $emailAddress, $merge = [], $confirm = true);
// Use $confirm = false to skip double-opt-in if you already have permission.
// This method will update an existing subscriber and will not ask an existing subscriber to re-confirm.

// Unsubscribe a member (set status to 'unsubscribed'):
Mailchimp::unsubscribe($listId, $emailAddress);

// Archive a member (no longer counts towards audience limits):
Mailchimp::archive($listId, $emailAddress);

// Permanently delete a member record:
Mailchimp::delete($listId, $emailAddress);
// Use with care: deleted members cannot be re-added without the user subscribing via a Mailchimp-hosted form with double-opt-in confirmation.

// Directly call the API:
Mailchimp::api($method, $endpoint, $data = []); // Returns an array.

For access to all the member properties available in the v3 API, use the Member class to subscribe and update list members:, _(*2)

$member = (new NZTim\Mailchimp\Member($email))
    ->merge_fields(['FNAME' => 'First name'])
    ->email_type('text')
    ->confirm(false);
Mailchimp::addUpdateMember($listId, $member);

As with the subscribe() method, double-opt-in is default but existing members will not be asked to re-verify so you can use the same methods for create and update without needing to check., _(*3)

Errors

Exceptions are thrown for all errors.
Networking/communications errors will usually be of the type ConnectionException.
API errors will be of the base type NZTim\Mailchimp\MailchimpException, e.g. incorrect API key, list does not exist.
NZTim\Mailchimp\Exception\MailchimpBadRequestException includes a response() method that attempts to provide the response body as an array, for automated handling of some error types.
Gotchas with merge fields:
- If you receive an error adding a new subscriber, check for required merge fields.
- Merge fields are case-sensitive.
- Mailchimp::addUpdateMemberSkipMergeValidation() is available if needed.

Examples

// Laravel:
// Subscribe a user to your list, existing subscribers will not receive confirmation emails
Mailchimp::subscribe('listid', 'user@domain.com');

// Subscribe a user to your list with merge fields and double-opt-in confirmation disabled
Mailchimp::subscribe('listid', 'user@domain.com', ['FNAME' => 'First name', 'LNAME' => 'Last name'], false);

// Subscribe/update a user using the Member class
$member = (new NZTim\Mailchimp\Member($email))->interests(['abc123fed' => true])->language('th');
Mailchimp::addUpdateMember('listid', $member);
