n8n Workflow Manager API: Remote Trigger & Info Retrieval

This workflow creates a powerful, secure API for managing n8n automations programmatically. It listens for HTTP requests via a webhook: POST to trigger any workflow by ID with custom input data, or GET to fetch info on specific workflows, all active/inactive ones, or summarized details using parameters like workflowId, mode, and includedWorkflows. Responses are clean JSON with success/failure status and data, enabling seamless integration without modifying target workflows.

Key benefits include remote control of n8n from external apps, scripts, or tools like Raycast (example GitHub extension provided), saving time on manual activations and enabling dynamic automation management. It's highly flexible for devs building custom dashboards, mobile apps, or CI/CD pipelines that interact with n8n instances.

Setup is straightforward: configure Header Auth on the webhook for API key security, add your n8n API credentials to info-fetching nodes, activate, and use the production webhook URL (path: workflow-manager). Use cases span app development, DevOps, and any scenario needing programmatic workflow orchestration, boosting productivity across teams.

Perfect for IT & development pros in education or beyond, this template unlocks n8n's full potential as a backend service.
