n8n Workflow Automation and Low-Code Orchestration

1. Overview & Business Value#

This comprehensive operational guide details the architecture, business workflows, configuration parameters, and execution steps for n8n Workflow Automation and Low-Code Orchestration within SmartERP.

The smarterp_n8n_bridge addon connects SmartERP with the enterprise n8n workflow engine, enabling non-developers to build complex multi-system automations.

Building an n8n Integration Pipeline#

1. In n8n, add a SmartERP Webhook Trigger node.
2. In SmartERP, configure webhook URL pointing to n8n listener.
3. Chain transformation nodes:
   • Extract customer name and total amount.
   • Dispatch formatted Telegram alert to sales management channel.
   • Create Google Sheets backup entry.

• Security Groups:
  • Integration Specialist (Technical ID: base.group_user)
  • System Administrator / API Director (Technical ID: base.group_system)
• Master Data Dependencies: Established API keys, configured payment providers, and verified external webhook callback endpoints.

3. Step-by-Step Configuration & Execution#
