Build social media integration once,
publish everywhere

Replace multiple platform APIs with one unified interface for publishing and analytics

Get started
POST /v1/posts
Terminal window
curl -X POST "https://api.postproxy.dev/v1/posts" \
     -H "Authorization: Bearer YOUR_API_KEY"
     -H "Content-Type: application/json" \
     -d '{
      "content": "Hello World!",
      "media": ["https://someurl.com/happyface.jpg"],
      "accounts": [777, 778]

Scheduling posts looks simple.
Making it work is not.

On the surface, it's just "publish later". In practice, scheduling becomes one of the hardest parts to build and maintain.
Teams underestimate scheduling until it starts breaking. What should be automation quickly turns into edge cases, retries, and manual fixes.

Different APIs
Each platform has its own publishing flow, timing quirks, and undocumented behavior.
Different constraints
Formats, media limits, text rules, validations - all inconsistent and enforced late.
Unclear failures
Errors are vague, delayed, or impossible to recover from automatically.
Manual intervention
When automation fails, humans step in to keep things from falling apart.

Scheduling is not "just a feature".
Reliable publishing needs a dedicated reliability layer.
That layer is Postproxy.

One request, all platforms handled

A single request replaces platform-specific logic, limits, and failures.

Platform APIs

Each platform's unique endpoints, rate limits, and constraints handled automatically

Format conversion

Content automatically transformed to match each platform's requirements

Authentication

OAuth flows, token storage, and automatic refresh managed for you

Delivery guarantees

Automatic retries, rate limit handling, quota awareness, and clear publish state reporting.

Add reliable publishing in three steps

A minimal setup to integrate Postproxy into your publishing pipeline.

When publishing becomes infrastructure

If this sounds familiar

Your publishing pipeline is already automated. Content is generated by LLMs, agents, or scripts and triggered by scheduled jobs, webhooks, or event driven workflows built with tools like n8n, Zapier, or custom automation.

Everything works until content needs to be published.

At that point, publishing becomes the least reliable part of the system. You end up normalizing AI generated output for every social platform, maintaining separate SDKs and API integrations, debugging partial failures and silent drops, and manually verifying what was actually published.

What should be a single pipeline step turns into a growing collection of platform specific edge cases, glue code, and operational checks inside an otherwise automated system.

What changes with Postproxy

A stable API for reliable social publishing

One integration that turns publishing into a predictable infrastructure layer across platforms.

Explicit publish states

You always know what succeeded, what failed, and why. Automatically and without manual checks.

Failures are handled by design

Retries, rate limits, and quotas are first class concepts, not error cases.

Scale without added complexity

Publishing ten items or ten thousand follows the same deterministic logic.

A single, stable publishing contract

One integration that stays stable even when social platforms don't.

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.

n8n workflow example showing PostProxy integration

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

No manual steps or platform-specific logic. Just one fully automated pipeline.

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.
