The task is to create a PHP-based omnichannel chat module that lets me manage Facebook, Instagram, and Telegram conversations from a single web dashboard. Core workflow • A settings page must let me securely connect the three platforms. • When someone writes to the linked Facebook Page, Instagram account, or Telegram bot, the message should appear instantly in the dashboard. • I must be able to send replies from the same interface, and the user should receive them in the original channel. Automation Automated DM replies are required for Facebook and Instagram. The logic can live in PHP or a simple rule engine inside the app; feel free to suggest the most reliable approach. Don't use any third-party platform APIs. Deliverables 1. Clean PHP codebase with database schema. 2. Settings page for OAuth / token management of Facebook, Instagram, Telegram. 3. Real-time message feed with reply input and read/unread status. 4. Configurable automated DM responder for Facebook & Instagram.
