  • Is it triggering while add to cart manually in the website? – Prathap Gunasekaran May 30 '19 at 11:12
  • its website is not in use. so I working through API calls, its not triggering – Praveen Negimani May 30 '19 at 11:20

checkout_cart_product_add_after is a frontent event.It is not work with Rest.

You can try with below event which can fire for all area frontend, backend, Rest API, rest soap.

$this->_eventManager->dispatch('sales_quote_add_item', ['quote_item' => $item]);
