n8n-nodes-happ

n8n community node for the Happ platform — connect messenger channels (Telegram, Instagram, WhatsApp) and AI voice assistants to your n8n workflows via the Happ Platform API.

Installation

In n8n: Settings → Community Nodes → Install → enter n8n-nodes-happ.

Manual install into a self-hosted n8n:

cd ~/.n8n/nodes
npm install n8n-nodes-happ

Credentials

1. Sign in at my.happ.tools and generate an Access Token (or POST /api/companies/{companyId}/access-tokens with a JWT). The token is company-scoped (happ_...).
2. In n8n create Happ API credentials: paste the token (happ_...) and pick the environment (Production / Development).

Nodes

Happ

The node is marked usableAsTool, so an n8n AI Agent can call it as a tool.

Happ Trigger

Polling trigger. Events:

• New Message — a single chat, or all chats via the last-message endpoint (in all-chats mode only the latest message per chat is delivered each poll and at most the first 100 chats are watched); optional role filter (e.g. only User messages).
• New Chat — fires when a new conversation appears.
