Making and publishing a back-office Prestashop module

Hi, I would like to make and publish a free Prestashop module to send orders to an external webservice, to generate shipping labels. The external webservice should be called with a simple href, I already have the PHP code to generate the link (see below). Here are the specifications : - add a page/area to Prestashop's back-office to fill some informations : - the API key (********** in the code below) - a string key for each Prestashop's shipping method (?????????? in the code below) - add a button for every order in the back-office's orders list, with an href to the link generated by the code below - you should replace "alert(response.tracking_number)" with some JS code to send back the tracking number to Prestashop and : - save the tracking number in the order - change the order status to "Shipped" - those pages should be in French only (I will give you the translations) - the module should be compatible with every versions of Prestashop since 1.7.0 - I will create an account on [login to view URL] and I would like you to publish the module, or explain me how to do that $order = new Order($id); $customer = new Customer($order->id_customer); $address = new Address($order->id_address_delivery); $request = [ 'api_key' => '**********', 'shipment[reference]' => $id, 'shipment[shipping_method]' => '??????????', 'shipment[weight]' => $order->getTotalWeight() * 1000, 'shipment[company]' => $address->company, 'shipment[last_name]' => $address->lastname, 'shipment[first_name]' => $address->firstname, 'shipment[address1]' => $address->address1, 'shipment[address2]' => $address->address2, 'shipment[zip_code]' => $address->postcode, 'shipment[city]' => $address->city, 'shipment[country]' => $address->country, 'shipment[email]' => $customer->email, 'shipment[phone]' => $address->phone_mobile ?: $address->phone, ]; $href = "$.ajax({ method: 'POST', url: '[login to view URL]', data: " . str_replace('"', "'", json_encode($request)) . ", success: function (response) { if (typeof response == 'object') { if (response.print_instructions_javascript) { eval(response.print_instructions_javascript); } alert(response.tracking_number); } }, error: function (response) { alert([login to view URL]([login to view URL](13))); } });";
