n8n Telegram /carousel Workflow: Gemini IG Carousel Drafts

Generate Instagram carousel drafts in minutes—directly from Telegram with n8n + Google Gemini

With this n8n Telegram /carousel workflow, you can type a simple command in Telegram, send a topic and audience to the Google Gemini API, and instantly receive an 8-slide Instagram carousel draft back in the same chat.

What this workflow does

• Telegram trigger: Starts when a new Telegram message is received.
• Command check: Verifies the message text starts with /carousel. If not, the workflow stops.
• Parses input: Reads the command content and splits it into topic and audience using | (pipe). It also captures the Telegram chat ID.
• Calls Google Gemini: Sends the topic and audience to generativelanguage.googleapis.com via the generateContent endpoint, requesting a JSON-only 8-slide carousel structure.
• Processes results: Cleans and parses the returned JSON, then formats the slides into a Markdown message.
• Replies in Telegram: Sends the formatted carousel draft back to the originating chat.

Use cases

• SaaS marketing teams: Rapidly draft carousel copy concepts for new features, campaigns, or announcements.
• Automation engineers: Test AI-to-Instagram content generation flows using Telegram as the control panel.
• Solopreneurs: Generate audience-specific carousel drafts without leaving chat—just send /carousel topic | audience.

Technical details

• Nodes/logic used: Telegram Trigger, if, code, HTTP Request, and Telegram send.
• AI integration: Google Gemini API via generativelanguage.googleapis.com generateContent.
• Setup required: Create a Telegram bot, add Telegram credentials in n8n, start a chat with the bot, then add your Google Gemini API key (replace YOUR_GEMINI_API_KEY in the HTTP Request URL).

Use the command format /carousel topic | audience (or rely on workflow defaults when parts are omitted) to generate your 8-slide Instagram carousel draft.
