n8n Workflow Manager API

## ▶️ POST Route: Execute a Target Workflow

This branch handles `POST` requests to dynamically execute another n8n workflow.

### 1. Map Webhook Request to Fields:
* Extracts `workflowId` from the incoming request's query parameters (e.g., `?workflowId=YOUR_TARGET_WORKFLOW_ID`).
* Extracts the entire `body` of the POST request to be passed as `workflowInputData` to the target workflow.
    * **Note:** If you send custom data in the body, ensure the triggered workflow is designed to receive and process it (e.g., via a "Workflow data" trigger node or by accessing `$json.workflowInputData` in its initial nodes).

### 2. Execute Workflow:
* The `workflowId` to execute is dynamically set using the value from the previous step:
    `{{ $('Map webhook request to fields').item.json.targetWorkflowId }}`
* **Wait for Completion:** This node is configured to wait until the sub-workflow (the one being executed) finishes before continuing.
* Handles success and error responses separately.
