Postproxy

Postproxy is a unified API infrastructure designed to transform social media publishing from a chaotic, unreliable process into a predictable, data-driven operation. It serves developers, automators, and growth teams who manage content distribution across multiple platforms like Instagram, Facebook, YouTube, LinkedIn, and X. The core value proposition is eliminating the 80% of operational overhead typically associated with multi-platform publishing—platform-specific API integrations, OAuth management, rate limit handling, content format adaptation, and failure recovery. By providing a single, stable endpoint, Postproxy reduces integration time from weeks to hours and increases publish success rates by handling platform inconsistencies and failures automatically. It is engineered for systems where content is generated programmatically via LLMs, automation tools like n8n and Zapier, or CI/CD pipelines, turning publishing into a reliable infrastructure layer that scales deterministically with your output volume.

Unified Multi-Platform API

Postproxy consolidates the disparate APIs of Instagram, Facebook, YouTube, LinkedIn, and X into one consistent RESTful endpoint. This eliminates the need to maintain separate SDKs, manage unique rate limits for each platform, and write custom logic for platform-specific field validation. A single POST request with your content and target profiles triggers the entire cross-platform publishing workflow, streamlining development and reducing codebase complexity by over 70% compared to native integrations.

Automated OAuth & Token Management

The platform fully manages the entire authentication lifecycle, including initial OAuth flows, secure token storage, and automatic token refresh. This removes the bureaucratic hurdle of managing app reviews, permission scopes, and policy shifts across multiple vendors. Developers can connect social accounts once, and Postproxy ensures persistent, authorized access, preventing publishing failures due to expired tokens and simplifying account sprawl across dozens of pages, brands, or clients.

Intelligent Content Adaptation & Validation

Content is automatically transformed to meet each platform's unique format rules, media limits, and text validation requirements. This includes resizing images, converting video formats, truncating text to character limits, and adapting post structures. This feature ensures a "Hello World!" post behaves correctly everywhere, increasing deliverable content yield by adapting AI-generated or standardized content for platform-specific consumption without manual intervention.

Guaranteed Delivery with Explicit State Handling

Postproxy provides robust delivery guarantees through automatic retries, intelligent rate limit handling, and quota awareness. Every publish request returns an explicit state—success, failed, or pending—with clear reasons for any failure. This eliminates silent drops and delayed errors, providing full visibility into publishing operations and reducing the need for manual status checks and cleanup by operational teams.

AI-Powered Content Distribution Pipelines

Teams using LLMs (like GPT-4 or Claude) or AI agents to generate blog summaries, promotional posts, or news updates can route this content directly through Postproxy. It automatically adapts the AI output for each social platform's format and publishes at scale. This creates a fully automated content pipeline from generation to distribution, increasing output volume by 10x while maintaining a 99%+ publish success rate across networks.

Multi-Channel Marketing Automation

Marketing and growth teams managing campaigns across multiple brands, regions, or client accounts use Postproxy to orchestrate synchronized or sequenced posts. By integrating with workflow tools like n8n or Zapier, they can trigger publishes based on events, schedules, or data updates. This eliminates manual cross-posting and ensures consistent messaging, improving campaign launch speed and reliability.

Developer-Led Product Launch Communications

SaaS companies and developer tools can integrate Postproxy into their CI/CD pipelines to automate release announcements and changelog updates. A script can generate release notes, and Postproxy handles publishing to all relevant social channels simultaneously. This turns a manual, error-prone task into a deterministic, tracked step in the deployment process, ensuring timely and accurate communication.

Agency Social Media Management

Digital marketing agencies managing dozens of client accounts use Postproxy to centralize publishing operations. It simplifies access control, handles client account onboarding via OAuth, and provides a unified audit log. This reduces the operational cost per client by consolidating tools and minimizing platform-specific troubleshooting, allowing agencies to scale their service offerings profitably.

What platforms does Postproxy support?

Postproxy currently provides a unified API for publishing to Instagram (including Reels), Facebook (Pages and Groups), YouTube (Shorts and standard videos), LinkedIn (Pages and personal profiles), and X (formerly Twitter). The platform handles each network's unique media formats, API endpoints, and publishing rules automatically through a single request.

How does Postproxy handle platform API changes or failures?

Postproxy's infrastructure is designed to absorb platform instability. Our system monitors API health, implements automatic retries with exponential backoff for transient failures, and gracefully handles rate limits. When a platform introduces a breaking change, our team updates the integration on our side, ensuring your publishing pipeline remains stable without requiring code changes on your end.

Is my data and social media access secure?

Yes. Security is a foundational principle. All OAuth tokens are encrypted at rest. API requests are transmitted over HTTPS. We operate on a zero-trust internal network model and never store your raw media files permanently after processing. You maintain full control over which accounts are connected and can revoke access at any time.

Can I schedule posts for future publication?

Yes, Postproxy supports scheduled publishing. You can include a scheduled_at timestamp in your API request. The platform will queue the post and handle all delivery logic, including platform-specific timing considerations and retries, at the specified time, providing the same reliability guarantees as immediate publishes.

Postproxy offers a tiered pricing model designed to scale with your publishing volume. A Free plan is available to get started, which includes a limited number of monthly posts and core platform support. Paid plans increase the number of posts, profiles, and supported platforms, and add advanced features like webhooks, priority support, and enhanced analytics. You can view detailed plan comparisons, post limits, and current costs directly on the Postproxy website's Pricing page.
