Execute Custom Hooks in a Module

[vivek_23]

Hello All, 

 

I am trying to figure out how to execute custom hooks attached to a module. Below is my code for install and hook function. 

public function install(){
     return parent::install() && $this->registerHook('actionMyCheckout');
}

public function hookActionMyCheckout($params){
     var_dump($params);
     exit;// just curious what's in the params for now.
} 

I will explain in a bit more detail-

• I am making a checkout plugin for our Prestashop customers for a  different sales channel(not website). So, there will be a single checkout URL which our system will hit of a client's store, along with cart data. 
• Once that particular URL is triggered, I want to execute my custom hook function and add all products to the cart on his/her website. 
• I am aware of a hook function called actionCartSave, but don't want to hook my checkout function to it, as my function will also be called every time someone checks out on the client's website which is trivial and reduces efficiency of checkout process for client's visitors. 
• Please guide me as to how to execute my custom hook ONLY on hitting a particular URL endpoint. 

Do I need to play around with Dispatcher?

Note: Since this will be a module, I don't have control over other files on the client's store backend. Checkout should work once our checkout module is installed by the client on his backend.
