AI Tool Compatibility

This node is fully compatible with n8n's AI Agent nodes and can be used as an AI tool. The node includes usableAsTool: true making it appear in AI tool lists automatically.

Setup Requirements

Important: For community nodes to work as AI tools, you must set this environment variable in your n8n instance:

N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true

Features for AI Usage

• ✅ All fields support $fromAI() expressions for dynamic parameter population
• ✅ Appears in AI Agent tool lists when environment variable is set
• ✅ Can be connected to AI Agent's ai_tool port
• ✅ Works with MCP trigger nodes

Using with AI Agents

1. Set the environment variable (see above)
2. Add the AI Agent node to your workflow
3. Add the Gravity Forms node to your workflow
4. Connect Gravity Forms to the AI Agent's ai_tool port
5. Configure the tool name and description in the AI Agent settings
6. The AI can now:
   • Submit form entries based on AI-extracted data
   • Retrieve and process form submissions
   • Manage forms dynamically
   • Query entry data based on natural language requests

Example AI Tool Configuration

In the AI Agent node settings:

• Tool Name: "Gravity Forms Manager"
• Tool Description: "Manages WordPress Gravity Forms. Can create, read, update, and delete forms and entries. Use this to submit form data, retrieve submissions, or manage form configurations."

Example Workflows

Watch for New Form Submissions

1. Gravity Forms Trigger (New Entry) → 2. Process Entry Data → 3. Send to CRM → 4. Send Email Notification

Submit Form with Validation

1. Webhook Trigger → 2. Gravity Forms (Submit) → 3. Check Validation → 4. Return Response

AI-Powered Form Submission

1. Webhook Trigger → 2. AI Agent (with Gravity Forms tool) → 3. Submit Form → 4. Respond to Webhook

File Upload from Cloud Storage

1. Get File URL from S3/Google Drive → 2. Gravity Forms (Create Entry with File) → 3. Send Confirmation

Process Updated Entries

1. Gravity Forms Trigger (Updated Entry) → 2. Get Full Entry → 3. Compare Changes → 4. Update Database

File Upload Support

The node supports file uploads to Gravity Forms file fields in two ways:

URL-based uploads (Recommended)

• Provide a public URL to the file (S3, Google Drive, Dropbox, etc.)
• The node will validate the URL is accessible
• The URL is sent directly to Gravity Forms

Binary data uploads

• For entry creation: Files are encoded and sent with the entry
• For form submission: Currently requires URL (binary not yet supported)

Example Usage

When creating an entry with a file upload field:

1. Select the file upload field from the dropdown
2. Choose "URL" as the file source
3. Provide the file URL (e.g., https://example-bucket.s3.amazonaws.com/document.pdf)

The node automatically handles:

• URL validation
• File accessibility checks
• Proper field mapping

Resources

• Gravity Forms Documentation
• Gravity Forms REST API v2
• n8n Community Nodes Documentation

Troubleshooting

Forms not loading in dropdown?

1. Check credentials: Use the Test Connection button
2. Verify API is enabled: Go to Forms > Settings > REST API in WordPress
3. Check permissions: Ensure your API key has the gravityforms_edit_forms capability
4. URL format: The node automatically adds /wp-json/gf/v2 to your WordPress URL
5. Update the node: Make sure you have version 0.2.1 or later

Common Issues

• "No Forms Found": Check that you have forms created in Gravity Forms and API access is enabled
• Authentication errors: Verify your consumer key and secret are correct
• CORS errors: Ensure your WordPress site allows API access from your n8n instance
