One API for Facebook & Instagram

Publishing, inbox, insights, widget, MCP. Your users click one consent screen. You call one REST API. MissLess owns the Meta app, the tokens and the app review.

Quickstart social.missless.tel

MissLess Social API is a social-media engine you plug into your own product. One Meta app, reviewed and verified by MissLess. Your users connect their Facebook Pages and Instagram accounts with a single consent screen. You publish, schedule, read the inbox and reply through a REST API, drop in the widget where you do not want to build UI, and let an AI assistant drive it over MCP.

The response is the post with status: "published" and a permalink per network. Media was uploaded one call earlier, the accounts were connected by the user through a hosted link. That is the whole loop: see it end to end.
