1
Trigger Node

Use a Webhook trigger or Manual trigger. Alternatively, connect to your CMS webhook so every new blog post automatically triggers a social media campaign.
2
AI Adaptation Node

Use an HTTP Request node to call OpenAI with three separate prompts for each platform. Twitter: 280 chars max, punchy, with hashtags. LinkedIn: professional tone, 300 words max, with a question hook. Mastodon: conversational, 500 chars, community-focused.
3
Platform Nodes

Add Twitter/X API node, LinkedIn API node, and Mastodon API node. Configure each with the adapted content from the previous step. Set scheduling times based on best engagement windows for each platform.
4
Image Attachment

If the source content has an image, use the HTTP Request node to download it, then attach it to the social posts. For LinkedIn, generate a custom image using an AI image API with the post title as prompt.
5
Analytics Loop

After 24 hours, trigger a second workflow that collects engagement metrics (likes, comments, shares) from all three platforms and saves to a Google Sheet for tracking.
