Integrate Perfect Day into PrestaShop.

Step 1 — Create a property for the coupon ID

PrestaShop has so-called "features" that allow you to attach any data to products.

1. Create new property

   PrestaShop admin → Catalog → Attributes & Properties → Properties → „"Add new property"". Name: Perfect Day Coupon ID. Save. Then under „"Values"" Assign a value to each coupon variant (e.g. 15114, 15115).

2. Assign property to each product

   In the product editor → Tab „"Functions"" → „"Perfect Day Coupon ID"" select → assign the appropriate value → save.

   The properties option is more suitable than a custom field, since custom fields in PrestaShop are intended only for customer input, not for backend links.

Step 2 — Custom module for the webhook

The module listens for the hook actionValidateOrder and sends the order to Perfect Day.

1. Create a module structure

   The module consists of two files:

   Directory structure

   modules/perfectdayconnector/ ├── perfectdayconnector.php └── config.xml

2. perfectdayconnector.php

   The module's main file registers the order hook, reads the coupon ID property for each product, and sends the webhook. Approximately 80 lines.

   name = 'perfectdayconnector'; $this->tab = 'export'; $this->version = '1.0.0'; $this->author = 'DigElite'; $this->bootstrap = true; parent::__construct(); $this->displayName = $this->l('Perfect Day Connector'); $this->description = $this->l('Sends orders with Perfect Day Coupon IDs to the platform.'); $this->ps_versions_compliancy = ['min' => '1.7', 'max' => _PS_VERSION_]; } public function install() { return parent::install() && $this->registerHook('actionValidateOrder') && Configuration::updateValue('PFD_API_USER', '') && Configuration::updateValue('PFD_API_PASSWORD', ''); } public function uninstall() { Configuration::deleteByName('PFD_API_USER'); Configuration::deleteByName('PFD_API_PASSWORD'); return parent::uninstall(); } public function hookActionValidateOrder($params) { $order = $params['order']; if (!$order) return; $items = []; foreach ($params['cart']->getProducts() as $p) { $couponId = $this->getProductFeatureValue($p['id_product'], 'Perfect Day Coupon-ID'); if (!$couponId) continue; $items[] = ['coupon_id' => (int)$couponId, 'count' => (int)$p['cart_quantity']]; } if (empty($items)) return; $customer = new Customer($order->id_customer); $payload = [ 'shop_order_id' => (string) $order->reference, 'shop_type' => 'prestashop', 'shop_domain' => Tools::getShopDomain(), 'customer' => [ 'email' => $customer->email, 'name' => trim($customer->firstname . ' ' . $customer->lastname), 'locale' => substr(Context::getContext()->language->iso_code, 0, 2), ], 'items' => $items, 'order_total_cents' => (int) round($order->total_paid * 100), 'currency' => Context::getContext()->currency->iso_code, 'placed_at' => $order->date_add, ]; $user = Configuration::get('PFD_API_USER'); $pwd = Configuration::get('PFD_API_PASSWORD'); $ch = curl_init('https://plattform.deinperfectday.de/wp-json/perfectday/shop/webhook/order'); curl_setopt_array($ch, [ CURLOPT_POST => 1, CURLOPT_RETURNTRANSFER => 1, CURLOPT_HTTPHEADER => [ 'Content-Type: application/json', 'Authorization: Basic ' . base64_encode($user . ':' . $pwd), ], CURLOPT_POSTFIELDS => json_encode($payload), CURLOPT_TIMEOUT => 15, ]); curl_exec($ch); curl_close($ch); } private function getProductFeatureValue($idProduct, $featureName) { $sql = 'SELECT fvl.value FROM ' . _DB_PREFIX_ . 'feature_product fp' . 'INNER JOIN'. _DB_PREFIX_ . 'feature_lang fl ON fl.id_feature = fp.id_feature' . 'INNER JOIN'. _DB_PREFIX_ . 'feature_value_lang fvl ON fvl.id_feature_value = fp.id_feature_value' . ' WHERE fp.id_product = ' . (int)$idProduct . "AND fl.name = '". pSQL($featureName) . "'". 'LIMIT 1'; return Db::getInstance()->getValue($sql); } }

3. Install module

   Pack the module folder as a ZIP file, then open the PrestaShop admin panel → Modules → Module Manager → Upload Module → Insert ZIP file → install → activate.

4. Configure credentials

   Enter your login details as configuration values — PFD_API_USER (your WordPress username) and PFD_API_PASSWORD (Your application password). This can be done via the module configuration or directly in the ps_configuration-Tabel.

Step 3 — Test order

1. Place and check order

   Place a test order in the PrestaShop frontend and complete the payment (a bank wire transfer is sufficient for testing). Then check: Platform back office → Perfect Day → Shop orders (Entry with shop_type=prestashop?) and the customer mailbox to the brand email with print button.
