n8n Workflow: Claude + PostWire Auto Draft & Publish Posts

Draft and publish social posts from n8n—using Claude for writing and PostWire for multi-network publishing (with your approval)

This n8n workflow turns a chat request into native social media drafts across multiple networks, shows you previews for approval, and then publishes only the approved version using PostWire—no surprises.

What this workflow does

• Receives your request via the n8n Chat trigger (chat URL or embedded chat), starting a conversation with the workflow.
• Uses Anthropic Claude with conversation memory to interpret what you want and preserve context for follow-up edits.
• Generates per-network post drafts via the PostWire community node (e.g., LinkedIn and Bluesky). This step drafts only—nothing is published yet.
• Returns draft previews in chat so you can review content for each selected platform.
• Requires explicit approval before publishing. Once you approve, the workflow calls PostWire again to publish the approved drafts to the networks you selected and reports the publish result (including platform hints).

Use cases

• Multi-platform content drafting: Ask Claude for a post idea and receive LinkedIn + Bluesky-ready drafts for review.
• Human-in-the-loop publishing: Prevent accidental live posts by approving each revision directly in chat.
• SaaS/operator workflow: Quickly turn product updates or announcements into consistent native network posts without manual formatting.

Technical details

• n8n Chat Trigger to run the workflow through a chat interface.
• Anthropic Claude chat model with buffer window memory to maintain conversation context.
• PostWire community node to generate draft posts and, after approval, publish them to selected networks using valid lowercase PostWire network IDs (for example: linkedin, bluesky).
• Includes workflow nodes such as sticky note, n8n-nodes-langchainagent, n8n-nodes-langchainchat, n8n-nodes-langchainlm, and n8n-nodes-langchainmemory.

Setup note: Install n8n-nodes-postwire, create a PostWire account, connect your social networks, and add your PostWire API key as an n8n credential. Add an Anthropic credential for Claude (or swap the chat model as needed).
