Recent Improvements (v0.4.10+)

The SimPRO node has been completely redesigned for better user experience:

Before vs After

Before (Manual JSON):

Query: {"search": "test", "pageSize": 10}

After (Structured Fields):

Company ID: 0

  • 🏷️ Better operation names: [GET] List all jobs instead of long paths
  • 💡 Helpful errors that show exactly where to set missing parameters
