Postproxy × n8n

Publish and schedule social media posts directly from n8n with a single node that actually survives production workflows.

One node and one payload per publish. Postproxy carries platform differences, rate limits, and retries so your workflow graph stays straightforward.

Build real publishing pipelines in n8n

Postproxy is designed for people who automate systems. It is not another UI tool. It is a publishing primitive you can drop into production-grade n8n workflows. Generate content, enrich it with AI, upload assets, decide where to publish and let Postproxy handle the final mile.

What this example shows

  • A scheduled trigger pulls content from Airtable
  • AI generates post text and visuals
  • Media is uploaded and turned into a public URL
  • Assets are combined into a final payload
  • Postproxy publishes the post to the selected social networks

Content moves from source to social accounts in one pipeline, with Postproxy handling each network end to end.

What this enables

If it fits into an n8n workflow, it can be published:

Generative content pipelines

Automate content creation from LLMs and AI agents, then publish seamlessly across platforms without manual intervention.

CMS-driven social automation

Connect your content management system to social media. When content is published in your CMS, automatically share it across networks.

Multi-account and multi-brand posting

Manage multiple social media accounts and brands from a single workflow. Route content to the right accounts automatically based on your rules.

Fully hands-off release announcements

Automate product launches and updates. Trigger announcements from your release pipeline, CI/CD, or version control system.

Multi-language posting from one source

Generate localized versions of the same post using AI. Publish each language to the correct accounts based on simple routing rules.

AI-powered weekly digests

Collect internal updates, changelogs, or blog posts. Generate a weekly summary and publish it to multiple social channels without manual editing.

How Postproxy fits into n8n workflows

  1. Your workflow produces content

    RSS, CMS, Airtable, AI, webhooks. If n8n can produce the content, Postproxy can publish it.

  2. n8n triggers a Postproxy node

    One node receives a single payload and applies it across every selected profile, keeping your workflow linear.

  3. Postproxy handles the ugly parts

    Platform quirks, validation rules, rate limits, retries and scheduling are handled outside your workflow.

  4. n8n receives structured per account results

    Success, partial success and failure are reported explicitly. So you can retry, alert, log or react with intention.

Multi-platform publish
Schedule with confidence
Per-account results
Retry without duplicates
Traceable post outputs
Rate-limit handling
Idempotent publishing
n8n-friendly API
