Postproxy

Navigating the treacherous seas of social media publishing is a quest fraught with hidden perils. Each platform is a separate island with its own cryptic laws, shifting sands of API rules, and dragons guarding their gates in the form of app reviews and rate limits. Postproxy is your seasoned cartographer and steadfast ship, transforming this chaotic archipelago into a single, charted course. It's a unified API that serves as your one reliable port of call for publishing to Instagram, Facebook, YouTube, LinkedIn, and X. Designed for the modern explorer—developers, automators, and builders using tools like n8n, Zapier, LLMs, or CI/CD pipelines—Postproxy automates the entire voyage. It handles the OAuth rituals, battles rate limits, retries failed landings, and expertly adapts your treasure (content) to each destination's unique customs. This turns publishing from a risky, manual expedition into predictable infrastructure, letting you generate AI content, route by rules, and publish at scale while it manages the operational storms. With a free plan to begin your journey and an MCP server included for seamless tool integration, Postproxy is the essential compass for anyone looking to conquer social media automation.

The Unified API Compass

Forget carrying a different map for every platform. Postproxy provides a single, reliable API endpoint—your master compass. This one consistent interface replaces the need to juggle multiple platform-specific SDKs, endpoints, and authentication schemes. You chart your course once, and Postproxy translates your command into the precise native tongue each social media island requires, ensuring your message lands exactly as intended, everywhere.

Automated OAuth & Token Vault

The quest for access tokens is a tedious ritual of permissions and refreshes. Postproxy acts as your trusted quartermaster, securely managing the entire OAuth flow. It stores your tokens in a fortified vault and handles automatic refreshes behind the scenes. You simply connect your accounts once, and the key to each kingdom is maintained for you, eliminating the dreaded "token expired" shipwreck mid-journey.

Resilience Engine: Retries & Rate Limits

The waters are rough with invisible quotas and sudden rate limit squalls. Postproxy's resilience engine is your ship's reinforced hull. It intelligently handles platform rate limits with automatic back-offs, retries failed publish attempts, and is fully aware of quota constraints. This ensures your content isn't lost to a temporary storm, providing delivery guarantees and clear, actionable reports on the state of your cargo.

Content Adaptation Forge

Your golden treasure (a perfect post) cannot be presented the same way on every shore. Postproxy is your onboard forge, automatically transforming and adapting your content to meet each platform's specific demands. From image dimensions and video formats to text length validation and feature support, it reshapes your raw material into the correct form, ensuring it is accepted and displayed flawlessly across all destinations.

The AI Content Caravan

You're leading a caravan of AI-generated content from GPT, Claude, or other agents. The creative journey is automated, but the final leg—publishing—hits a bottleneck of manual formatting and platform checks. Postproxy becomes the final, automated trade route. It receives the raw AI output, forges it for each platform, and reliably delivers the goods to all your social storefronts, turning a generative pipeline into a complete, hands-free expedition.

The Multi-Client Agency Galleon

Managing fleets of social accounts for dozens of clients is like commanding a galleon in a fog—account sprawl, permission chaos, and inconsistent posting. Postproxy serves as your unified command deck. It centralizes access control for all client accounts and provides one stable API to publish across them all. This eliminates operational drift, ensures consistent delivery, and lets you scale your agency's reach without the complexity.

The Event-Driven Automation Schooner

Your system is a sleek schooner powered by n8n, Zapier, or CI/CD winds, triggering actions from database updates to webhooks. The moment you need to broadcast an event to social media, you hit turbulent, custom-coded waters. Postproxy integrates as a reliable first-mate module. Your automation simply passes the payload to its unified API, and it handles the entire publishing voyage, making social alerts a predictable part of your automated workflow.

The Scalable Campaign Flagship

Launching a campaign across multiple platforms should be a triumphant fleet maneuver, not a series of fragile, single-ship sorties. Postproxy is your flagship's command center. Whether publishing ten previews or ten thousand campaign assets, you use the same, stable API. It manages the scale automatically, handling the logistics of rate limits and retries, so you can focus on the strategy of the campaign conquest.

What platforms does Postproxy support?

Postproxy currently charts courses to the major social media continents: Instagram, Facebook, YouTube, LinkedIn, and X (formerly Twitter). It handles the unique API protocols, content rules, and authentication requirements for each, providing a single unified interface to publish across this entire landscape. The supported fleet is designed to cover the most critical territories for automated publishing.

How does Postproxy handle platform API changes or failures?

Think of Postproxy as your crew of seasoned lookouts and navigators constantly monitoring the horizon. When a platform changes its API or experiences endpoint instability, the Postproxy team updates the integration on its side. Your integration—the single API call you make—remains unchanged. This means you are insulated from the shifting sands, maintaining a stable publishing contract even when the underlying platforms are turbulent.

Is my data and access secure with Postproxy?

Absolutely. Security is the fortified hull of our ship. We treat your API keys and social media access tokens as the most valuable treasure. Tokens are encrypted and securely stored. We follow industry-best practices for data protection and authentication. You retain full control over the accounts you connect, and can revoke Postproxy's access at any time directly from the platform's settings, just as you would with any other integrated app.

Can I schedule posts or just publish immediately?

Postproxy is designed as the reliable delivery engine for your publishing pipeline. While its core strength is executing publishes via API, advanced scheduling is typically managed upstream in your automation tool (like n8n or Zapier) or application logic. You can send requests to Postproxy to publish immediately or, by controlling the trigger time in your scheduler, effectively schedule posts by deciding when the API call is made, giving you flexible command over your publishing timetable.
