What is PostPeer?
PostPeer is a unified social media API that lets developers post, schedule, and analyze content across Instagram, Twitter, YouTube, Facebook, TikTok, LinkedIn, Pinterest, Bluesky, Threads, and YouTube Shorts from a single endpoint. It handles OAuth flows, supports webhooks for delivery confirmation, and works with no code platforms like Zapier, Make, n8n, and MCP. A free tier is available and no credit card is required to start.
Why PostPeer works
Building social posting into a product means writing and maintaining an OAuth flow and content pipeline for every platform, each of which changes APIs unpredictably. PostPeer collapses that into one API and one authentication path, so a SaaS team or AI agent can post to ten networks at once instead of staffing an integrations team.
PostPeer features
- Single API for ten networks. Post to Instagram, Twitter, YouTube, Facebook, TikTok, LinkedIn, Pinterest, Bluesky, Threads, and YouTube Shorts from one request.
- Built in scheduling. Schedule posts in advance with automatic timing and delivery so users do not run their own scheduler.
- Managed OAuth. Platform authentication is handled automatically, removing the need to build each platform's connect flow.
- Real time delivery webhooks. Webhooks confirm post status seconds after publishing so apps can show accurate state to users.
- Multi account management. Hundreds of social accounts can be managed under a single API key for agencies or SaaS platforms with many tenants.
- No code integrations. Connectors for Zapier, Make, n8n, RapidAPI, and MCP let non developers wire it into existing tools.
Who PostPeer is for
- SaaS founders adding social posting to their product who do not want to build and maintain ten platform integrations.
- AI agent builders shipping autonomous marketing agents that need a reliable cross network publishing layer.
- Agencies managing dozens of client social accounts who want a programmable backend for internal tooling.
- Automation operators using Make or n8n who need a node to publish to ten networks without juggling per platform credentials.
