Prestashop 1.7 Payment module

Question

I am creating a credit card payment module for prestashop 1.7

I don't know how to send my post values on an external url and receive its response if the transaction is success or failed.

You have to make things like this :

• Make a module ( https://validator.prestashop.com/generator ) and extend it with PaymentModule, not just Module.

• Register interesting hooks ( http://build.prestashop.com/news/module-development-changes-in-17/ ) and make a function like this in your module :

    public function hookHookName($params) { // Do things here } 

• Play with this Hook specially (first part is hook name and second are $params) :

   Hook::exec('actionValidateOrder', array( 'cart' => $this->context->cart, 'order' => $order, 'customer' => $this->context->customer, 'currency' => $this->context->currency, 'orderStatus' => $order_status )); 

• Make calls (curl / file_get_contents for instance) on that moment before validating anything.
• A good way to know how to do it could be to download Paypal Module (it's free) and see how they did it.
