Generate Weekly n8n Execution Report and Email Summary


**Description:**

How it works

  • Automatically runs every 7 days to pull all n8n workflow executions from the past week
  • Merges execution data with workflow information to provide context
  • Generates a professional HTML report with execution statistics (errors, successes, waiting status)
  • Sends the formatted report with Outlook or Gmail

Set up steps

1. Configure n8n API Credential

  • Go to your n8n instance → Settings → API
  • Create a new API token with read access to workflows and executions
  • In this workflow, add a new "n8n" credential and paste your API token
  • This credential is used by two nodes: "Get all Workflows" and "Get all previous executions"

2. Connect Email Services

  • Configure your Outlook credential in the "Send a message outlook" node
  • Configure your Gmail credential in the "Send a message gmail" node
  • Set your preferred email recipients in both nodes

3. Adjust Schedule (Optional)

  • By default, the workflow runs every 7 days
  • Edit the "Schedule Trigger" node to change the interval if needed

Key features

Generate Weekly Workflow Analytics Reports with n8n API & Email Delivery

This n8n workflow automates the process of generating weekly analytics reports for your n8n workflows and delivering them via email. It leverages the n8n API to fetch workflow execution data, processes it, and then sends a consolidated report.

What it does

  1. Schedules Report Generation: Triggers the workflow weekly at a specified time.
  2. Fetches Workflow Data: Uses the n8n API to retrieve a list of all active workflows.
  3. Processes Workflow Executions: For each active workflow, it fetches its execution history.
  4. Filters and Aggregates Data: Filters the execution data to include only successful executions within the last week and aggregates relevant metrics.
  5. Generates Report: Compiles the aggregated data into a structured report.
  6. Sends Email Report: Delivers the generated report to a specified email address using either Gmail or Microsoft Outlook.

Prerequisites/Requirements

  • n8n Instance: An active n8n instance where this workflow will run.
  • n8n API Key: An API key for your n8n instance with sufficient permissions to read workflow and execution data.
  • Email Account:
    • Gmail Account: If using the Gmail node, a configured Gmail credential in n8n.
    • Microsoft Outlook Account: If using the Microsoft Outlook node, a configured Microsoft Outlook credential in n8n.

Setup/Usage

  1. Import the Workflow:
    • Copy the provided JSON code.
    • In your n8n instance, go to "Workflows" and click "New".
    • Click the "Import from JSON" button and paste the copied JSON.
  2. Configure Credentials:
    • n8n API: Locate the "n8n" node. You will need to set up an n8n API credential. This typically involves providing your n8n instance URL and an API key.
    • Email Service:
      • If using the "Gmail" node, configure your Gmail OAuth2 or API key credential.
      • If using the "Microsoft Outlook" node, configure your Microsoft Outlook OAuth2 credential.
  3. Customize Email Recipients:
    • In the "Gmail" or "Microsoft Outlook" node, update the "To" field with the email address(es) where you want to receive the weekly reports.
  4. Activate the Workflow:
    • Ensure the "Schedule Trigger" node is enabled and configured to your desired weekly schedule.
    • Activate the workflow by toggling the "Active" switch in the top right corner of the workflow editor.

The workflow will now automatically run on its schedule, generate the analytics reports, and send them to the specified email address.

PDF Invoice Extractor (AI) End-to-end pipeline: Watch Drive ➜ Download PDF ➜ OCR text ➜ AI normalize to JSON ➜ Upsert Buyer (Account) ➜ Create Opportunity ➜ Map Products ➜ Create OLI via Composite API ➜ Archive to OneDrive. --- Node by node (what it does & key setup) 1) Google Drive Trigger Purpose: Fire when a new file appears in a specific Google Drive folder. Key settings: Event: fileCreated Folder ID: google drive folder id Polling: everyMinute Creds: googleDriveOAuth2Api Output: Metadata { id, name, ... } for the new file. --- 2) Download File From Google Purpose: Get the file binary for processing and archiving. Key settings: Operation: download File ID: ={{ $json.id }} Creds: googleDriveOAuth2Api Output: Binary (default key: data) and original metadata. --- 3) Extract from File Purpose: Extract text from PDF (OCR as needed) for AI parsing. Key settings: Operation: pdf OCR: enable for scanned PDFs (in options) Output: JSON with OCR text at {{ $json.text }}. --- 4) Message a model (AI JSON Extractor) Purpose: Convert OCR text into strict normalized JSON array (invoice schema). Key settings: Node: @n8n/n8n-nodes-langchain.openAi Model: gpt-4.1 (or gpt-4.1-mini) Message role: system (the strict prompt; references {{ $json.text }}) jsonOutput: true Creds: openAiApi Output (per item): $.message.content → the parsed JSON (ensure it’s an array). --- 5) Create or update an account (Salesforce) Purpose: Upsert Buyer as Account using an external ID. Key settings: Resource: account Operation: upsert External Id Field: taxid_c External Id Value: ={{ $json.message.content.buyer.tax_id }} Name: ={{ $json.message.content.buyer.name }} Creds: salesforceOAuth2Api Output: Account record (captures Id) for downstream Opportunity. --- 6) Create an opportunity (Salesforce) Purpose: Create Opportunity linked to the Buyer (Account).

Key settings: pricebook2Id (hardcoded in script): e.g., 01sxxxxxxxxxxxxxxx Source lines: $('Message a model').first().json.message.content.products Output: { soql, codes } --- 8) Query PricebookEntries (Salesforce) Purpose: Fetch PricebookEntry.Id for each Product2.ProductCode. Key settings: Resource: search Query: ={{ $json.soql }} Creds: salesforceOAuth2Api Output: Items with Id, Product2.ProductCode (used for mapping). --- 9) Code in JavaScript (Build OLI payloads) Purpose: Join lines with PBE results and Opportunity Id ➜ build OpportunityLineItem payloads. Inputs: OpportunityId: ={{ $('Create an opportunity').first().json.id }} Lines: ={{ $('Message a model').first().json.message.content.products }} PBE rows: from previous node items Output: { body: { allOrNone:false, records:[{ OpportunityLineItem... }] } } Notes: Converts discount_total ➜ per-unit if needed (currently commented for standard pricing). Throws on missing PBE mapping or empty lines. --- 10) Create Opportunity Line Items (HTTP Request) Purpose: Bulk create OLIs via Salesforce Composite API. Key settings: Method: POST URL: https://<your-instance>.my.salesforce.com/services/data/v65.0/composite/sobjects Auth: salesforceOAuth2Api (predefined credential) Body (JSON): ={{ $json.body }} Output: Composite API results (per-record statuses). --- 11) Update File to One Drive Purpose: Archive the original PDF in OneDrive. Key settings: Operation: upload File Name: ={{ $json.name }} Parent Folder ID: onedrive folder id Binary Data: true (from the Download node) Creds: microsoftOneDriveOAuth2Api Output: Uploaded file metadata. --- Data flow (wiring) Google Drive Trigger → Download File From Google Download File From Google → Extract from File → Update File to One Drive Extract from File → Message a model Message a model → Create or update an account Create or update an account → Create an opportunity Create an opportunity → Build SOQL Build SOQL → Query PricebookEntries Query PricebookEntries → Code in JavaScript Code in JavaScript → Create Opportunity Line Items --- Quick setup checklist 🔐 Credentials: Connect Google Drive, OneDrive, Salesforce, OpenAI. 📂 IDs: Drive Folder ID (watch) OneDrive Parent Folder ID (archive) Salesforce Pricebook2Id (in the JS SOQL builder) 🧠 AI Prompt: Use the strict system prompt; jsonOutput = true. 🧾 Field mappings: Buyer tax id/name → Account upsert fields Invoice code/date/amount → Opportunity fields Product name must equal your Product2.ProductCode in SF. ✅ Test: Drop a sample PDF → verify: AI returns array JSON only Account/Opportunity created OLI records created PDF archived to OneDrive --- Notes & best practices If PDFs are scans, enable OCR in Extract from File. If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
