# PlugKit

> One API to publish, read, and reply across every social platform — built for developers and AI agents.

PlugKit is a single REST API that connects social and messaging accounts through
**official platform APIs** and lets you act on them — publish content, read and
send messages, manage comments — without integrating each platform yourself.

Today it supports **Instagram** and **WhatsApp** via Meta's official APIs, with
more platforms on the way.

## How it works

<Steps>
  <Step title="Create a profile">
    A profile groups the accounts you connect (think of it as a workspace).
  </Step>

  <Step title="Connect an account">
    Send your user through the platform's official OAuth flow. PlugKit stores the
    token and exposes the account.
  </Step>

  <Step title="Act through one API">
    Publish posts, read and reply to messages, manage comments — the same shape
    of request whatever the platform.
  </Step>
</Steps>
