Set up your **Telegram bot** token in the **Telegram node credentials**.\n4. Update the **_Chat ID_** in the **_Send Telegram Message_** node.\n5. Test the workflow to ensure everything is set up correctly.\n* **Notes**: Detailed telegram bot setup instructions are available in the [workflow's n8n page](https://n8n.io/workflows/2043-crypto-market-alert-system-with-binance-and-telegram-integration)."}, "typeVersion": 1}], "pinData": {}, "connections": {"Aggregate": {"main": [[{"node": "Split By 1K chars", "type": "main", "index": 0}]]}, "Schedule Trigger": {"main": [[{"node": "Binance 24h Price Change", "type": "main", "index": 0}]]}, "Split By 1K chars": {"main": [[{"node": "Send Telegram Message", "type": "main", "index": 0}]]}, "Binance 24h Price Change": {"main": [[{"node": "Filter by 10% Change rate", "type": "main", "index": 0}]]}, "Filter by 10% Change rate": {"main": [[{"node": "Aggregate", "type": "main", "index": 0}]]}}}
