Postproxy is a unified social media API that lets SaaS products, automation pipelines, and agencies embed publishing, comments, DMs, insights, and reviews into their own applications. It handles OAuth, token lifecycle, rate limits, and delivery retries across major networks, so teams avoid building and maintaining per-platform integrations. The platform runs on EU-hosted infrastructure and offers SDKs for TypeScript, Python, Ruby, Go, Java, .NET, and PHP.

Problem
Building and maintaining direct integrations with social media platforms requires significant engineering effort, including managing OAuth flows, token refreshes, per-platform rate limits, API changes, and delivery edge cases. Teams often spend weeks on app registration and review cycles, then face ongoing operational work for publishing, comments, DMs, and insights, which diverts resources from core product features.
Solution
Postproxy provides a single REST API and SDKs that replace per-platform integrations with one unified interface for publishing, comments, conversations, insights, and reviews. The platform handles OAuth, token lifecycle, rate limiting, retries with back-off, and delivery webhooks, so clients send one payload and Postproxy maps it to each network's rules. It also surfaces incoming comments, DMs, and reviews as structured webhook events, enabling automation tools like n8n, Make, or Zapier to react in real time. The service runs on EU-hosted infrastructure with GDPR compliance and is SOC 2 Type II certified, and it offers an MCP server for AI agents like Claude and Cursor to publish directly from their environments.
