N8n Integration

Connect n8n workflow automation to PassingRight for AI-powered workflows

n8n is a powerful workflow automation tool that can be enhanced with AI capabilities through PassingRight. This guide shows how to integrate PassingRight into your n8n workflows.

Using DevPass? This integration also works with a DevPass plan key. Use canonical model IDs without a provider prefix (claude-sonnet-4-5, not anthropic/claude-sonnet-4-5) — provider-pinned routing is not available on coding plans; the gateway picks the provider for you.

Prerequisites

  • An PassingRight account with an API key
  • n8n instance (self-hosted or cloud)
  • Basic understanding of n8n workflows
