Instagram News Carousel Automation with n8n, Gemini & Drive

Automate Instagram News Carousels in Minutes (GTA 6 Edition) — n8n + Gemini + Drive

This n8n workflow automatically scrapes today’s GTA 6 news, uses Google Gemini to write carousel hooks and captions, renders branded 1080×1350 slides, uploads them to Google Drive, and publishes the result as a live Instagram carousel through the Meta Graph API.

What this workflow does

Designed for repeatable, hands-off Instagram publishing, it works end-to-end like this:

• Manual run trigger: You start it by executing the workflow.
• Scrape today’s links: It fetches the gta6.channel news page, extracts today’s external article links, limits the list, and downloads each article’s HTML.
• Extract content & images: It extracts readable article text plus a set of unique, non-boilerplate images from each article, then aggregates stories into a single payload.
• Gemini carousel writing: Google Gemini selects 3–5 distinct items and returns a strict JSON response containing a hook headline, per-slide headlines/captions with highlight phrases, and a final Instagram caption.
• Render slides with Gotenberg: The workflow builds styled HTML for a hook slide, one slide per selected story (using unique images), plus an end card—then renders each slide into 1080×1350 JPEG files via Gotenberg.
• Upload & publish: Each image is uploaded to Google Drive, made public, used to create Instagram carousel item containers, bundled into a carousel, and published via the Meta Graph API.

Use cases

• Publish daily GTA 6 news carousels without manual copywriting or slide design.
• Test automation pipelines for social content: scrape → LLM drafting → slide rendering → Drive storage → Instagram publishing.
• Give SaaS operators and automation engineers a production-style example of multi-API orchestration in n8n.
