You're tasked with developing a bot plugin that can be seamlessly integrated into any website to streamline the process of taking orders and handling payments for a restaurant. The plugin should offer the following functionalities:

Menu Upload: The plugin should provide an interface for restaurant staff to easily upload the menu items, including their names, descriptions, prices, and any available customizations or options. The menu should be displayed in a user-friendly format on the website.

Order Placement: Customers visiting the website should be able to interact with the bot plugin to place their orders. The plugin should present the menu options to the customer and allow them to select the desired items, specify any customizations, and indicate the quantity.

Order Management: The plugin should be capable of managing multiple orders simultaneously. It should keep track of the order details, including the items, quantities, customizations, and any special instructions provided by the customer. The plugin should provide an intuitive interface for restaurant staff to view and manage incoming orders efficiently.

Payment Processing: The bot plugin should seamlessly integrate with the NAME_1 API for payment processing. It should securely collect and process payment information, such as credit card details or other preferred payment methods, using NAME_1's secure payment gateway. The plugin should handle transactions, including authorization, capturing funds, and handling refunds, while ensuring the security of sensitive payment information.

Order Confirmation: After the payment is successfully processed, the plugin should generate an order confirmation, including a summary of the items ordered, the total cost, and an estimated delivery or pickup time. The confirmation should be displayed to the customer on the website, and optionally, be sent via email or SMS.

Your task is to design and implement the bot plugin, ensuring it can be easily integrated into any website without major code modifications. The plugin should offer a smooth and intuitive ordering experience for customers while leveraging the NAME_1 API for secure payment processing. Consider providing clear instructions for website owners on how to integrate the plugin, and consider adding customization options to match the plugin's appearance with the website's design.
