Processing submissions in n8n

n8n is a workflow automation platform that lets you connect and handle hundreds of different services through a visual editor with native AI capabilities. Each workflow is made up of several nodes: specific actions that trigger or process the workflow data. Plumsail Forms provides a community node to handle form submissions in n8n.

With n8n and Plumsail Forms, you can:

  • Store form submissions in your preferred database

  • Send notifications to your team chat on new submissions

  • Interpret and categorize user feedback with an AI agent

  • Update inventory systems based on order form submissions

  • …and much more

Note

The amount of data that can be handled by Plumsail Forms depends on your current subscription plan.
