I have custom module and my code structure is as per service contact.


Now i have a dispatch event in my model file

$this->_eventManager->dispatch('vendor_register_success', $eventParams);

As per REST API standard and as per the this solution i added event in specific module where it comes from.


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

and My observer looks like this


 public function execute(\Magento\Framework\Event\Observer $observer)
        echo "In execute"; exit;

but this event is not dispatching. What am i missing Because as per the solution i need to add events in webapi_rest folder in etc folder.

Try below code for dispatch event.

$this->_eventManager->dispatch('vendor_register_success', [$eventParams]);

Instead of

$this->_eventManager->dispatch('vendor_register_success', $eventParams);

As second parameter should be an array. This may help you.

This can be done by defining events.xml in webapi_rest folder.


Magento is doing it in quote module for sending mail.

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="sales_model_service_quote_submit_success">
        <observer name="sendEmail" instance="Magento\Quote\Observer\Webapi\SubmitObserver" />
