Send low-stock inventory reorder emails from Snowflake with Claude and Outlook

## Quick overview This workflow runs daily, queries Snowflake for items at or below their reorder level, and groups them by supplier. For each supplier, it uses Anthropic Claude to draft a reorder email, optionally appends details to a Google Docs log, and sends the email via Microsoft Outlook. ## How it works 1. A Schedule Trigger fires every day at 07:00 (Europe/Helsinki timezone) and passes through a Workflow Config node that holds your optional Google Docs log ID. 2. A Snowflake query fetches all inventory rows where current_stock <= reorder_level. If no items qualify, the workflow exits cleanly via a Pass Through node with no further action. 3. A Code node groups the low-stock items by supplier_name, producing one batch per vendor. A SplitInBatches loop then processes each supplier one at a time. 4. For each supplier, a Set node extracts the supplier email, item count, and a pre-rendered Markdown item list, then passes everything to an LLM chain powered by Claude (claude-sonnet-4-6). 5. Claude generates a concise, professional reorder request email body in Markdown, constrained by a system prompt to return only the email content with no preamble. 6. The Markdown output is converted to HTML and optionally appended as a one-line entry to a Google Docs audit log (skipped if no doc ID is configured). The workflow then sends the HTML email to the supplier via Microsoft Outlook before advancing to the next vendor. ## Setup 1. Open the Workflow Config node and set log_doc_id to the document ID from your Google Doc URL (the string between /d/ and /edit). Leave it empty to skip audit logging entirely. 2. Add your Snowflake credentials to the Query Snowflake DB node and verify the query matches your database name, schema, and table. The expected columns are item_id, item_name, current_stock, reorder_level, supplier_name, and supplier_email. 3. Add your Anthropic credentials to the Claude Email Generation node. 4. Add your Microsoft Outlook credentials to both the Send Reorder Email and Send Error Alert nodes. Update the toRecipients field in Send Error Alert to your alert address. 5. If logging is enabled, add your Google Docs credentials to the Log to Google Docs node. 6. In n8n Settings > Error Workflow, point to a dedicated error-handler sub-workflow that wires into the Send Error Alert node (it is intentionally unwired in this workflow). ## Requirements - Snowflake account with an inventory table containing current_stock, reorder_level, supplier_name, and supplier_email columns - Anthropic API credentials (claude-sonnet-4-6) - Microsoft 365 account with Outlook access - Google Docs OAuth2 credentials (only if audit logging is enabled) ## Customization - Adjust the Snowflake query to match your schema, add filters by warehouse or category, or join additional tables for richer item metadata. - Modify the Claude system prompt in Build Email Draft to change tone, language, or email structure — for example to generate Finnish-language emails or include purchase order references. - Change the cron expression in When 7am Daily to run at a different time or frequency. - Extend the log entry format in Log to Google Docs to include item names, SKUs, or a hyperlink back to the workflow execution. - Replace the Google Docs logging step with a Slack notification, a row insert into PostgreSQL, or any other audit destination by swapping the node after Check Configured Doc ID.

Flag delayed Shopify orders with Slack, Google Sheets and Gmail

## Quick overview This workflow runs daily to check Shopify for open, unfulfilled orders older than two days, classifies them by delay severity, posts a digest to Slack, logs each delayed order to Google Sheets, and emails an HTML summary report via Gmail. ## How it works 1. Runs every day at 08:00 (server time) on a schedule trigger. 2. Calls the Shopify Admin REST API to fetch up to 250 open orders with `fulfillment_status=unfulfilled`. 3. Calculates each order’s age in days and extracts key details (customer, totals, items, and Shopify Admin order link). 4. Filters to only orders delayed by 2+ days and labels each one as WARNING (2–4 days), CRITICAL (5–7 days), or ESCALATION (8+ days). 5. Checks whether any delayed orders exist and stops without notifying if the delayed list is empty. 6. Builds a Slack message grouped by severity and posts the delay digest to the configured Slack channel. 7. Appends each delayed order as a row in a Google Sheets tracker, then aggregates the list and sends an HTML summary email via Gmail to the operations manager. ## Setup 1. Add Shopify Admin API credentials (HTTP header auth) and replace `YOUR_STORE` in the Shopify API and admin order URLs with your store domain. 2. Add Slack credentials and set the target channel ID in the Slack message step. 3. Add Google Sheets credentials, set `YOUR_GOOGLE_SHEET_ID`, and ensure the worksheet named “Fulfillment Delay Tracker” exists with matching columns. 4. Add Gmail credentials and set `YOUR_OPS_MANAGER_EMAIL` to the recipient address for the summary report. 5. Adjust the cron schedule and the delay thresholds (2/5/8 days) in the filtering and severity rules if needed.

Assess Salesforce deal risk with Gmail, Outlook, OpenAI and Slack alerts

## Quick Overview This workflow runs every six hours to pull open Salesforce opportunities, enriches selected deals with Gmail and Microsoft Outlook email context, uses OpenAI to score deal risk, writes the assessment back to Salesforce, and notifies teams in Slack with optional email escalation for critical deals. ## How it works 1. Runs every 6 hours and queries Salesforce for up to 100 open Opportunities via the REST API. 2. Stops the run and posts a Slack message if the Salesforce fetch returns an error. 3. Normalizes each Opportunity, computes activity/close-date metrics, and routes deals with missing required fields to a Slack channel for manual data cleanup. 4. Applies a heuristic triage and immediately marks non-risky deals as healthy in Salesforce to avoid unnecessary AI analysis. 5. For triaged deals, pulls recent related messages from Gmail and Microsoft Outlook, merges them, and builds a compact email engagement context (participants, reply counts, and silence gap). 6. Sends the CRM and email context to OpenAI to produce a structured risk score, drivers, and recommended actions, then validates and cleans the AI output. 7. Updates Salesforce with the assessed risk fields and, for non-low risk deals, posts a detailed Slack alert (with cooldown suppression) and emails leadership when the risk level is Critical. ## Setup 1. Add Salesforce OAuth2 credentials, set the SALESFORCE_INSTANCE_URL environment variable, and ensure the Opportunity custom fields used for risk tracking (for example Risk_Score__c, Risk_Level__c, Risk_Summary__c, and Deal_Health__c) exist. 2. Add OpenAI credentials and confirm the selected model (gpt-4o-mini) is available in your OpenAI account. 3. Add Slack OAuth2 credentials and update the target channel IDs for Salesforce failure alerts, incomplete-deal alerts, and risk alerts. 4. Add Gmail OAuth2 credentials and Microsoft Outlook credentials (optional) so the workflow can retrieve deal-related email threads. 5. Set the LEADERSHIP_EMAIL environment variable (or edit the node default) to define where Critical-risk escalation emails are sent.
