Generate Professional Email Signatures in HTML & PDF with Gmail Delivery

This n8n workflow automates the creation of professional email signatures in both HTML and PDF formats, then delivers them via Gmail. It's designed to streamline the process of generating consistent and branded signatures for individuals or teams.

What it does

This workflow performs the following key steps:

1. Receives Input: It starts by listening for incoming data via a Webhook. This data is expected to contain the necessary information for generating an email signature.
2. Prepares Data: An "Edit Fields (Set)" node processes the incoming data, likely structuring or transforming it for subsequent use in the signature generation.
3. Generates Signature (HTML/PDF): An "HTTP Request" node is used to interact with an external service or API to generate the email signature. Based on the directory name, this step likely involves generating both HTML and PDF versions of the signature.
4. Processes Output: A "Code" node executes custom JavaScript, which could be used to further process the generated signature data, extract specific parts, or prepare it for email delivery.
5. Delivers via Gmail: The "Gmail" node sends an email containing the generated signature(s) to the designated recipient(s).
6. Responds to Webhook: Finally, the "Respond to Webhook" node sends a response back to the original caller of the webhook, indicating the successful completion of the workflow.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• Webhook Trigger: An external system or application configured to send data to the n8n webhook URL.
• External Signature Generation Service/API: An API endpoint that can generate email signatures (HTML and/or PDF) based on provided data. The "HTTP Request" node will need to be configured with the URL and authentication for this service.
• Gmail Account: A configured Gmail credential within n8n to send emails.

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure Webhook:
   • Activate the "Webhook" node.
   • Copy the test or production webhook URL. This is the endpoint your external system will send data to.
3. Configure "Edit Fields (Set)": Review and adjust the fields being set or transformed based on your input data structure.
4. Configure "HTTP Request":
   • Set the URL to your external signature generation service.
   • Configure the Method (e.g., POST) and Body to send the necessary signature data (e.g., name, title, company, contact info) to the service.
   • Add any required Headers for authentication (e.g., API keys).
5. Configure "Code": If the external service returns data that needs further manipulation before sending via Gmail, update the JavaScript in the "Code" node accordingly.
6. Configure "Gmail":
   • Select or create a new Gmail OAuth2 credential.
   • Set the To email address (e.g., from the webhook input).
   • Configure the Subject and Body of the email. You will likely attach the generated HTML and/or PDF signature here.
   • Ensure the Operation is set to "Send an Email".
7. Configure "Respond to Webhook": Customize the response body if needed.
8. Activate the Workflow: Once all nodes are configured, activate the workflow.

Now, whenever data is sent to the webhook, the workflow will trigger, generate the signature, and send it via Gmail.
