Postproxy is a unified social media API that replaces per-platform integrations with a single REST endpoint for publishing, engagement, and analytics across Instagram, TikTok, YouTube, X, LinkedIn, and other major networks.
What is Postproxy?
Postproxy is an API-first platform that lets developers publish content, reply to comments, respond to DMs, and retrieve insights through one interface. It takes a single payload (text, image, video) and maps it to each connected platform’s format rules, returning per-platform outcomes. The service runs on EU-hosted infrastructure and is built by the Postproxy team (no parent company named on the page).
Key Features
- One API for publishing and engagement — REST endpoints (e.g.,
POST /v1/publish) plus official SDKs for Node, Python, Ruby. Handles retries, status logs, and webhooks for every platform result.
- Multi-platform output from a single payload — Send one post; Postproxy converts formats for Instagram, Twitter, LinkedIn, TikTok, YouTube, Facebook, Threads, Pinterest, Bluesky, Telegram, and Google Business (latter coming soon).
- Full engagement flow — Reply to comments, answer DMs, and manage reviews across all connected platforms through the same API.
- Agentic workflow support — MCP server, skills, and OpenClaw integration for Claude, Cursor, and automation stacks.
- No-code automation integrations — Verified nodes for n8n, official app on Make, and verified integration with Zapier.
- Analytics and transparency — Statuses, timestamps, per-platform logs, and stats included in API responses; webhooks notify on completion or failure.
- Enterprise-grade security — Data encrypted at rest and in transit; OAuth flows only; GDPR compliant; SOC 2 Type II certification in progress.
Who is it for?
- SaaS companies embedding social publishing into their own product — provision a scoped environment per customer; users connect through your UI without ever creating a Postproxy account.
- Automation and AI developers — use the API or Claude Code skill as a single social step in workflows (e.g., post updates, reply to comments triggered by external events).
- Agencies managing multiple brand accounts — smart queues and profile groups keep each client’s posts, comments, and DMs logically separated.
What can you do with Postproxy?
- Publish across 11+ platforms at once — Send one API call with an image, video, or text; Postproxy handles format conversion and error mapping per network.
- Automate replies and DM responses — Build bots that monitor comments on Instagram, LinkedIn, or TikTok and reply via the same API without switching contexts.
- Embed social features into your product — Let your users connect their own Instagram or LinkedIn accounts; Postproxy proxies all publishing and engagement through your brand.
