MADIAD Hub is a single REST endpoint that publishes to 22 channels — TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Threads, Pinterest, Reddit, Bluesky and Google Business Profile, plus chat (Telegram, Discord, Slack), the fediverse (Mastodon, Nostr, Lemmy), blogs (WordPress, dev.to, Hashnode), Whop and listmonk. Manage many brands or client accounts as profiles, publish in one call, and let the Hub handle scheduling, idempotency, and delivery callbacks.

Quickstart

Make your first cross-platform post in under five minutes.

Authentication

Generate an API key and authorize requests.

Channels accept different kinds of post, and connect in two different ways. YouTube takes video only; Slack, dev.to and listmonk take text only; eleven channels have no OAuth login and are linked with your own webhook, API key or application password instead. The full matrix is on Channels.

Why MADIAD Hub

  • One integration, 22 channels. Send the same request once; the Hub fans out to every target you list.
  • Profiles for multi-brand workflows. Agencies, creators, and ops teams can publish on behalf of many accounts from one API key.
  • Built-in scheduling. Pick an exact timestamp or drop the post into a recurring queue.
  • Idempotent by design. Safe to retry — duplicates collapse on a key you control.
  • Webhooks with signatures. Every event is HMAC-signed so you can trust the payload.

​
Base URL

All Hub endpoints accept and return application/json unless noted. Media uploads use multipart/form-data.

​
SDK and tooling

  • HTTP — works from any language. See Quickstart for curl examples.
  • n8n — call the API from the built-in HTTP Request node. See the n8n guide.
  • Make — publish from a scenario with the HTTP module. See the Make guide.
