📱 Lightroom cloud to Instagram auto poster (AI captions)
⚡ 284 views · 📱 Social Media & Email Marketing
💡 Pro Tip — Heads up — if this workflow’s Instagram scraping breaks (it happens whenever Meta updates their frontend), ScraperNode is a community node that handles profiles, posts, reels, and comments without any HTML parsing.
Description
Automatically publish Lightroom photos to Instagram with short, human-sounding AI captions. This workflow pulls the next item from your Data Table queue, generates an on-brand caption from alt text + metadata, uploads via Instagram Graph API, and marks it posted. Use it together with “Lightroom Cloud → Photos Queue (AI Alt Text)” and “Lightroom Image Webhook (Direct JPEG for Instagram).”
What it’s for
Hands-free Lightroom-to-Instagram posting: schedule, caption with AI, and publish consistently using the Instagram Graph API.
Parameters to set
- Instagram Graph API access token and Instagram Business/Creator account ID
- Posting schedule (cron/interval) + max posts per run
- Data Table name & status fields (posted timestamp, IG media ID)
- Caption rules: tone, max length, hashtags policy, CTA style
- Image source URL: public endpoint of Workflow 2 (Lightroom Image Webhook)
Works best with
Workflow 1: Lightroom Cloud → Photos Queue (AI Alt Text)
Workflow 2: Lightroom Image Webhook (Direct JPEG for Instagram)
