Use OpenPMM to connect social accounts and create posts through one API. You do not need a separate integration for each provider. OpenPMM is in limited access. These pages document the available public API. They do not document features that are in development. ## Start here Create an API key and list the workspaces that it can use. Learn how one Post moves from a draft to a published state. Create a draft, publish it, and check the Post status. See the video and image limits for each destination. Read the API rules and browse the endpoints. Run OpenPMM workflows from a terminal or coding agent. Add OpenPMM directly to an MCP-compatible agent. Audit the complete API-only client and contribute on GitHub. ## The OpenPMM model An **account** owns API credentials and workspaces. A **workspace** contains destinations, assets, and Posts. A **destination** is a connected publishing target. A **Post** contains content and its publishing state.
