Create & Monitor Personalized Google Forms via Webhooks

Create & Monitor Personalized Google Forms via Webhooks (n8n)

Need to generate a customized Google Form for each customer and automatically capture their chosen option? This n8n workflow copies a template Google Form, personalizes it, publishes it to accept responses, then monitors answers in real time using a Google Forms watch + webhook-driven execution resume.

What this workflow does

• Starts with customer inputs: You manually run the workflow and provide the Google Form template ID, customer name, and a destination Google Drive folder ID.
• Copies the template into the customer folder: The workflow uses the Google Drive API to copy the template form into the target folder, then stores the new form ID along with the workflow’s resume webhook URL in an n8n Data Table.
• Personalizes and publishes the form: It fetches the new form via the Google Forms API, updates the form title/description and the choice options, and publishes the form so responses can be submitted.
• Sets up response monitoring: It creates a Google Forms watch that publishes response events to a Google Cloud Pub/Sub topic.
• Receives Pub/Sub notifications: An n8n webhook receives the notification, finds the matching resume URL in the Data Table by form ID, and resumes the original execution.
• Extracts the selected answer: After resuming, it fetches the latest responses from the Google Forms API, extracts the selected choice value, and sends it to a placeholder step for your custom processing.

Use cases

• Launch a unique “intake” or “selection” Google Form per customer and trigger downstream automation based on their selection.
• Collect preference choices (e.g., plan tier, questionnaire options) and route each response to your internal systems.
• Run SaaS onboarding flows where a form response determines next steps.
