About Postproxy
Postproxy is a unified social media API designed for agencies, SaaS products, and AI-driven workflows. It simplifies publishing, engagement, and analytics by replacing per-platform integrations with a single API endpoint. The tool handles OAuth authentication, token management, platform-specific format conversion, rate limits, retries, and failure reporting, allowing users to publish content to multiple networks with one request. Postproxy integrates seamlessly into existing automation stacks, including LLMs, AI agents, and tools like n8n or Zapier, enabling generated or localized content to be validated, transformed, and delivered reliably across platforms. It is built for teams that need social media integrations to work reliably within their own products, offering sandbox mode for testing and official APIs for platforms like YouTube, Twitter/X, TikTok, LinkedIn, Instagram, Facebook, and others. The service emphasizes security, compliance, and fast performance, running on European infrastructure with enterprise-grade encryption and GDPR compliance. Postproxy is particularly suited for SaaS products embedding social features, automation pipelines, and agencies managing multiple client accounts without losing track of scope or data. Support is provided by a team that reads logs, ensuring troubleshooting assistance when issues arise.
