**1.** In Google Drive create a **ToDeploy** folder and a **Deployed** folder
+ Update \"**Google Drive Trigger -ToDeploy folder**\" to your ToDeploy folder
+ Update \"**Move JSON file to Deployed folder**\" to you Deployed folder
**2.** Create a **n8n API key**:
+Go to Settings > n8n API
+Select Create an API key
+Copy API Key
**3.** In \"**Get Existing Workflow Tags**\" node:
Create n8n API Authentication
**Authentication:** Predefined Credential Type
**Credential Type:** n8n API
Create new credential:
+Paste in API key
+Baseurl: https://SUB.DOMAINNAME.com/api/v1/
**4.** Add n8n API authentication to:
+ \"**Create n8n Workflow**\" node
+ \"**Set Workflow Tag**\" node
**5.** Add your N8N instance URL to the **N8N_Instance_URL** variable in \"**Set n8n URL variable**\" node.
**6.** Run **\"Get Workflow Tags\"** node and copy the ID of your chosen tag.
**7.** In \"**Set n8n API URL & Tag ID variables**\" node:
+ Add the Workflow Tag ID to the **N8N_Instance_Tag** variable
+ Add your N8N instance URL to the **N8N_Instance_URL** variable
**9.** Set workflow to Active
**10.** Add n8n json files to Google Drive folder
