How this works
Efficiently capture new sign-ups from your website forms and automatically add them as users in Notion, ensuring your database stays current without manual entry. This workflow suits teams managing memberships, courses, or communities who rely on Notion for organisation, saving hours on administrative tasks. The key step involves querying Notion to check if the user already exists before creating a new entry with their name, email, and assigning them to the current semester via the Notion integration.
Use this workflow when handling frequent form submissions that need immediate Notion updates, such as event registrations or newsletter sign-ups. Avoid it for one-off entries or if your forms require complex validation beyond basic name and email extraction. Common variations include adding Slack notifications for new users or integrating with Google Sheets for backup logging.
