n8n-nodes-hpdu-auth

Schleifenbauer hPDU Authentication Node for n8n

This package provides a custom n8n community node that implements the official Schleifenbauer hPDU WEBAPI authentication mechanism (hPDU-auth-v1).

The node encapsulates the full authentication flow described in the Schleifenbauer documentation:

• retrieving the user identifier and server timestamp
• generating the HMAC-SHA256 signature
• constructing the 64-bit authentication token
• returning a ready-to-use Authorization header

The output of this node can be reused by one or more HTTP Request nodes to call any hPDU API endpoint.

✨ Features

• Implements hPDU-auth-v1 exactly as specified by Schleifenbauer
• Secure credential handling via n8n credentials
• No passwords exposed in workflow execution data
• Reusable authentication output for multiple API calls
• Optional debug output for troubleshooting
