n8n Workflow: Generate Ethereum/Solana Blockchain Audit Reports with PDF Export to Drive & Notion

This n8n workflow provides a robust automation for generating blockchain audit reports for Ethereum and Solana, converting them to PDF, and then exporting them to Google Drive and Notion. It acts as a backend service, triggered by an external webhook, to deliver comprehensive audit documents and notifications.

What it does

This workflow automates the following steps:

1. Receives a Request: It starts by listening for incoming data via a webhook, which likely contains the necessary information (e.g., blockchain type, address, report parameters) to generate an audit report.
2. Generates Report (External API Call): It makes an HTTP request to an external API to generate the actual blockchain audit report. The specifics of this API call (e.g., endpoint, payload) would be configured within the HTTP Request node.
3. Processes Report Data (Code Execution): A Code node is included, suggesting that the workflow performs custom JavaScript logic on the data received from the audit report generation API. This could involve formatting, extracting specific details, or preparing the data for subsequent steps.
4. Exports to Google Drive: The generated audit report (likely in PDF format, or converted to PDF within the workflow) is uploaded to a specified Google Drive folder.
5. Exports to Notion: The audit report information, or a link to the report, is then added to a Notion database or page.
6. Sends Email Notification: An email notification is sent, likely to inform relevant stakeholders that the report has been generated and is available.
7. Responds to Webhook: Finally, the workflow sends a response back to the original webhook trigger, indicating the successful completion of the process and potentially providing links to the generated report.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• Webhook URL: An external system capable of sending HTTP POST requests to the n8n webhook URL.
• External Audit Report API: Access and credentials for an API that can generate blockchain audit reports for Ethereum and Solana.
• Google Drive Account: A Google account with access to Google Drive for storing PDF reports.
• Notion Account: A Notion account with an integration setup to allow n8n to create/update pages or database items.
• SMTP Server/Email Service: Credentials for an SMTP server or an email sending service configured in n8n to send notifications.
• n8n Credentials: Configured credentials within n8n for Google Drive, Notion, and your email service.

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure Webhook:
   • Activate the "Webhook" trigger node.
   • Copy the generated webhook URL. This URL will be used by your external system to initiate the workflow.
3. Configure HTTP Request:
   • Edit the "HTTP Request" node.
   • Set the correct URL for your blockchain audit report generation API.
   • Configure the HTTP method (likely POST) and add any necessary headers (e.g., API keys, content type) or body data based on your API's documentation.
4. Configure Code Node:
   • Review and modify the "Code" node to process the data returned by your audit report API as needed. This is where you would implement logic for data extraction, transformation, or PDF generation if not handled by the API.
5. Configure Google Drive:
   • Edit the "Google Drive" node.
   • Select your Google Drive credential.
   • Specify the operation (e.g., "Upload File") and the target folder where the PDF reports should be saved.
   • Map the file content and file name from previous nodes.
6. Configure Notion:
   • Edit the "Notion" node.
   • Select your Notion credential.
   • Configure the operation (e.g., "Create Page" or "Create Database Item").
   • Map the report details, including the Google Drive link, to the appropriate Notion properties.
7. Configure Send Email:
   • Edit the "Send Email" node.
   • Select your email credential.
   • Set the recipient(s), subject, and body of the email notification. You can dynamically include details from the generated report.
8. Configure Respond to Webhook:
   • Edit the "Respond to Webhook" node.
   • Define the response content that will be sent back to the triggering system (e.g., success message, report ID, Google Drive link).
9. Activate the Workflow: Save and activate the workflow.

Once activated, any HTTP POST request to the webhook URL will trigger the workflow, generating and distributing your blockchain audit reports.
