Instagram Auto-Publisher for Lightroom Photos (AI Captions)

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)
