What it does
Who’s it for This workflow is ideal for marketers, content creators, agencies, and small businesses that want to streamline the process of creating and publishing platform-optimized posts across multiple social media channels. How it works / What it does From a single user prompt, the workflow uses a custom system prompt and schema to generate tailored social media content for LinkedIn, Instagram, Facebook, Twitter (X), Threads, and YouTube Shorts. It creates platform-specific captions, hashtags, calls to action, and even AI-generated image suggestions, then routes the content to the correct publishing channel. How to set up Connect your social media platform credentials in n8n. Add your Google Docs links for the system prompt and content schema. Configure the IMGBBAPIKEY and any other required API credentials. Optionally connect Gmail and Telegram for approval workflows and notifications. Requirements n8n instance (self-hosted or cloud) API credentials for desired platforms Google Docs and Google Drive accounts How to customize the workflow Edit the system prompt and schema in Google Docs to adjust tone, style, and content format for each platform. Modify routing logic or add new platform integrations as needed.
