Its executable nodes use `code`, `googleSheets`, `httpRequest`, `if`, `limit`, `manualTrigger`, `openAi`, `set`, `splitInBatches`. The table and connection map below are derived from the JSON, not an inferred guarantee of behavior.\n\n## Setup\nImport inactive. Configure your own credentials and replace REPLACE_WITH_* values. Review external destinations and Code nodes before running.\n\n## Entry points\nWhen clicking ‘Test workflow’\n\n## Verification\nSanitized source candidate; not runtime-tested. This overview is generated from node metadata. Read the folder README for the connection map, credential types, and license.\n\n## Attribution\nhttps://github.com/Zie619/n8n-workflows/blob/94007c1445d9258a7da116646b79473e7c7c3282/workflows/Limit/0880_Limit_Code_Create_Webhook.json\nMIT; preserve source notices.",
