The workflow pulls stock and vendor data from Google Sheets on a schedule.\n2. It processes and merges this data, filtering for necessary reorders.\n3. Reorder information is aggregated, updated in a Google Sheet, and pushed to Slack.\n4. A secondary Slack-triggered flow handles customer queries by emailing internal users and updating a spreadsheet log.\n\n### Setup steps\n\n- - [ ] Configure Google Sheets credentials for all sheet nodes.\n- - [ ] Set up a Slack bot token and connect it to the Slack trigger/notification nodes.\n- - [ ] Link your Gmail account for the email notification node.\n- - [ ] Map the specific sheet IDs and ranges for all Google Sheets integrations.\n\n### Customization\n\nUsers can modify the reorder threshold logic in the merge nodes or adjust the Slack channel IDs for different notification routing." }, "typeVersion": 1 }, { "id": "f1c4e530-a110-42b5-978c-2c83f4961889", "name": "Sticky Note10", "type": "n8n-nodes-base.stickyNote", "position": [ 12592, 1008 ], "parameters": { "color": 7,
