Telegram Bot for Multi-Item Selection & Postgres Storage (Checkbox)

This n8n workflow creates a Telegram bot that fetches a list of items from a Postgres 'shop_list' table and presents them as selectable checkboxes for users to multi-select. Upon selection, it saves the user's choices back to the database and automatically deletes intermediate messages to maintain a tidy chat interface. Ideal for developers needing quick structured input collection via Telegram.

Benefits include streamlined user interaction without custom bot coding, reliable data persistence in Postgres, and reduced chat clutter. It saves significant development time by handling Telegram callbacks, database queries/updates, and cleanup in one automated flow, making it efficient for inventory or order systems.

Use cases span inventory management in travel/hospitality (e.g., selecting tour packages), e-commerce order customization, preference tracking for services, or any scenario requiring multi-choice input stored in a DB. Customize for selling modules by adjusting the shop_list contents.

Setup involves running a provided SQL script to create tables (replace schema), adding Telegram Bot Token and Postgres credentials in n8n. The workflow is modular, tagged for telegram, module, and sell functionalities.
