Verified User Profile Generator and Delivery - n8n Workflow

• SaaS Platforms: Businesses needing to verify user signups before granting access.


• Membership Sites: Organizations that require robust email validation for their registries.


• Technical Content Creators: Individuals looking for complex, real-world examples of integration and flow control using an n8n node structure.


• Automation Engineers: Professionals seeking a ready-to-use n8n templates for document generation and conditional logic.

Receiving accurate user data is critical, but manually validating emails and generating unique documents is time-consuming. This comprehensive n8n automation template solves this by providing an instant, secure, and professional verification and profile generation system.

The n8n workflow starts with a user submission, instantly verifies the email's validity using a specialized API, and conditionally branches the flow. If verification succeeds, it dynamically generates a stylized HTML profile, converts it into a PDF, attaches the document, and sends a personalized verification email via Gmail. All verified user data is simultaneously recorded in a centralized Google Sheet. If the email is invalid, the user receives a polite rejection notice, ensuring your database remains clean and trustworthy. This intricate n8n node sequence ensures high data integrity and a great user experience.

The entire process is orchestrated by a sequence of specialized n8n node operations:

1. Start: The n8n trigger, a Webhook node, receives new user data (Name, Email, Bio, etc.) via an HTTP POST request.


2. Verification: The data is passed to the Verifi Email n8n node, which checks the deliverability and validity of the email address.


3. Conditional Split: An IF node evaluates the verification result.

1. HTML Generation: On the success path, a Set n8n node generates a complex, dynamic HTML template for the user profile, injecting the received user data.


2. PDF Conversion: The HTML to PDF n8n node (using HTMLcsstoPDF API) converts the beautiful HTML structure into a high-quality PDF document.


3. Binary Download: An HTTP Request n8n node downloads the generated PDF file as binary data, preparing it for email attachment.


4. Email Delivery: The Send Profile Email - Gmail n8n node uses a personalized HTML body, attaches the downloaded PDF binary, and sends it directly to the verified user.


5. Data Logging: Finally, the Log to Google Sheets n8n node appends or updates the new user's verified details in a master spreadsheet, completing the full automated n8n workflow cycle.

To deploy this powerful n8n workflow template, follow these steps:

1. Import: Copy the provided JSON code and import it directly into your n8n instance.


2. Webhook Setup: Activate the 'Webhook - Receive User Data' n8n trigger. Copy the generated test or production URL, which you will use to send data from your frontend application.


3. Credentials: Set up the required credentials for the custom n8n nodes:

1. Testing: Run the n8n workflow manually or send a sample JSON payload to the webhook URL to ensure all steps execute correctly and the PDF is generated and delivered.

This n8n template utilizes several critical nodes for complex automation:

Webhook - Receive User Data (n8n trigger):
Function: Serves as the starting point, listening for incoming POST requests containing user signup details.
Key Configuration: HTTP Method set to POST; Path set to /create-profile.
Verifi Email (Custom n8n node):
Function: Performs real-time validation of the incoming email address to ensure deliverability and authenticity.
Key Configuration: Input email mapped dynamically using an expression {{ $json.body.email }}.
IF Email Valid? (n8n node):
Function: Directs the flow based on the result of the email verification (valid = true).
Key Configuration: Condition checks if $json.valid is true.
Generate HTML Template (Set n8n node):
Function: Constructs a complex HTML document using embedded CSS and dynamic data expressions to create the user's profile content.
Key Configuration: Creates a variable htmlcontent containing the full parameterized HTML structure.
HTML to PDF (Custom n8n node):
Function: Sends the generated HTML to the PDF service for conversion.
Key Configuration: Input is the {{ $json.htmlcontent }} variable.
Download PDF Binary (HTTP Request n8n node):
Function: Retrieves the actual PDF file as binary data, which is necessary for attaching files in the Gmail n8n node.
Key Configuration: Response format set to file; URL dynamically fetched from the preceding HTML to PDF output ($json.pdf_url).
Send Profile Email - Gmail (Gmail n8n node):
Function: Delivers the verification message and the generated PDF attachment to the user.
Key Configuration: Rich HTML message body; Attachments configured to use the binary output from the previous download step.
Log to Google Sheets (Google Sheets n8n node):
Function: Maintains a record of all successfully verified users.
Key Configuration: Operation set to Append or Update; Maps user data fields (Name, Email, Profession, City, Verified Status) to spreadsheet columns.
