Facebook Messenger Chatbot for Automated Replies

I am seeking a skilled freelancer to develop and implement an automated messaging system for Facebook Messenger. The primary goal is to create a chatbot or auto-responder that can automatically reply to incoming messages when I am unavailable. The system should be able to integrate seamlessly with Facebook Messenger to provide timely responses to inquiries. Key functionalities include: setting up customizable auto-reply messages, defining conditions for when auto-replies are active (e.g., Outside business hours, specific keywords), and ensuring reliable message delivery. The solution should be user-friendly for managing settings and content. Experience with Facebook Messenger API and chatbot development is essential.
