You need some understanding of Data in n8n, including Data structure and Data flow within nodes.

When building your logic, you'll use n8n's Core nodes, including:

• Splitting: IF and Switch.
• Merging: Merge, Compare Datasets, and Code.
• Looping: IF and Loop Over Items.
• Waiting: Wait.
• Creating sub-workflows: Execute Workflow and Execute Workflow Trigger.
• Error handling: Stop And Error and Error Trigger.
