Magento 2 : Newsletter Subscription Event

Question

Is there an event in Magento 2 for Newsletter Subscription from the Profile page?

How do I find out when a user updates their newsletter subscription preference from this page?

Answer 1

You can use the predispatch/postdispatch events triggerred by the controller action class. In your case:

• controller_action_predispatch_newsletter_manage_save to observe a behavior BEFORE the save method is called.
• controller_action_postdispatch_newsletter_manage_save to observer a behavior AFTER the save method is called.

Fernando Miguel's answer doesn't work, change

newsletter_subscriber_save_before

For

newsletter_subscriber_save_after

After that, you'll be able to get the subscriber ID. Or even get the email using

$observer->getEvent()->getSubscriber()->getSubscriberEmail()

All these functions are available too:

 int getStoreId()
 $this setStoreId(int $value)
 string getChangeStatusAt()
 $this setChangeStatusAt(string $value)
 int getCustomerId()
 $this setCustomerId(int $value)
 string getSubscriberEmail()
 $this setSubscriberEmail(string $value)
 int getSubscriberStatus()
 $this setSubscriberStatus(int $value)
 string getSubscriberConfirmCode()
 $this setSubscriberConfirmCode(string $value)
 int getSubscriberId()
 Subscriber setSubscriberId(int $value)

Beyond controller_action_predispatch and controller_action_postdispatch if you want to work with model events just declare on your Vendor/Module/etc/frontend/events.xml:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="newsletter_subscriber_save_before">
        <observer name="vendor_module_observer_myobserver" instance="Vendor\Module\Observer\MyObserver" />
    </event>
</config>

On Magento\Newsletter\Model\Subscriber example you have $_eventPrefix variable. This variable will be used on Magento\Framework\Model\AbstractModel to generate dynamic dispatches for models at before and after events. Also on Magento\Newsletter\Model\Subscriber example we have $_eventObject to access the class methods as the following snippet observer example:

public function execute(Observer $observer)
{
    $subscriberId = $observer->getEvent()->getSubscriber()->getId();
    $this->logger->notice('subscriber ID: ' . $subscriberId);
}

Note that getSubscriber() uses get + $_eventObject = 'subscriber' value as described on var comments.
