Postproxy is a unified publishing API for social networks that replaces individual platform integrations. It handles platform-specific failures at publish time and removes the operational mess by providing one stable publishing layer across platforms.

Postproxy offers platform APIs that handle each platform's unique endpoints, rate limits, and constraints automatically. It provides format conversion where content is automatically transformed to match each platform's requirements. The service manages authentication including OAuth flows, token storage, and automatic refresh. It also includes delivery guarantees with automatic retries, rate limit handling, quota awareness, and clear publish state reporting.

The product works through a single API request that replaces platform-specific logic, limits, and failures. Integration involves three steps: getting an API key, connecting social media accounts, and publishing content via the unified API. Postproxy validates content, applies platform rules, and ensures delivery across all connected platforms.

Benefits include explicit publish states so you always know what succeeded and what failed, failures handled by design with retries and rate limits as first-class concepts, scaling without added complexity, and a single stable publishing contract that stays consistent even when social platforms change. It enables reliable social publishing infrastructure.

Postproxy is designed for developers who automate content at scale and people who automate systems. It integrates with tools like n8n workflows and supports building real publishing pipelines for generative content, CMS-driven automation, multi-account posting, release announcements, multi-language posting, and AI-powered weekly digests.
