Hi n8n team,

I just upgraded to Starter plan today (Order #73499854-143123535), but I’m having issues with API authentication.

Issue:
When testing the API with curl, I get “unauthorized” error:

curl -X GET "https://lynn-cafa-system.app.n8n.cloud/api/v1/workflows" \
-H "X-N8N-API-KEY: [my-api-key]"

Response: {"message":"unauthorized"}

if you mean you want to enter activation key, you need to see from settings n8n.io - Workflow Automation
