Web Form

Collect input from users through a shareable, published form

The Web Form node creates a form that users can fill out in their browser. When submitted, the form data flows into the next node. Use it to build intake forms, approval workflows, multi-step wizards, and any flow that needs human input.

​

When to Use It

• Collecting information from customers or team members
• Building multi-step intake processes
• Creating approval workflows where a human reviews and submits data
• Gathering structured input before running automations

​

How It Works

1. Add a Web Form node

   Drag a Web Form node onto your canvas. It can be the first node (trigger) or placed mid-flow for multi-step forms.

2. Design the form

   Open the Form Builder to add fields, text, and layout elements.

3. Publish the flow

   The form is only accessible when the flow is published.

4. Share the URL

   Each form gets a public URL:

   https://your-zygo-instance.com/api/forms/{node_id}
   

   Anyone with the link can view and submit the form — no login required.

​

Form Builder

The form builder lets you visually design your form with a variety of elements.

​

Input Fields

Element	Description
Text Input	Single-line text field
Text Area	Multi-line text field
Number	Numeric input
Email	Email input with validation
Select / Dropdown	Choose one option from a list
Multi-Select	Choose multiple options
Checkbox	Single true/false checkbox
Date	Date picker
File Upload	File attachment

​

Layout & Content

Element	Description
Heading	Section heading text
Paragraph	Static text or instructions
Divider	Horizontal separator

​

Form Settings

Setting	Description
Title	The form’s heading, displayed at the top
Description	Explanatory text shown below the title
Password Protection	Require a password before the form loads

​

Dynamic Content

Form titles, descriptions, and field labels support template syntax. This is especially useful in multi-step forms where earlier submissions populate later forms:

Welcome back, {{1_Web Form.form_data.name}}!

Templates are resolved when the form loads, pulling data from previous nodes via the form session.

​

Output

When a user submits the form, the Web Form node outputs:

Field	Description
form_data	An object containing all field values, keyed by field name
session_data	URL parameters passed to the form (if any)

Reference submitted values in downstream nodes:

Name: {{1_Web Form.form_data.name}}
Email: {{1_Web Form.form_data.email}}
Selected plan: {{1_Web Form.form_data.plan}}

​

Multi-Step Forms

You can chain multiple Web Form nodes together to create multi-step wizards. Zygo manages a form session that carries data between steps.

1. First form

   The user fills out the initial form. On submission, the flow runs until it hits the next Web Form node.

2. Processing

   Nodes between the forms can transform data, call APIs, or apply conditions to determine the next step.

3. Next form

   The user is redirected to the next form. Data from previous steps is available via templates, so you can prefill fields or personalize the form.

4. Completion

   After the last form, the flow continues to completion — sending emails, writing to tables, creating tickets, etc.

Use the Condition node between form steps to route users to different forms based on their previous answers — for example, showing a different set of questions based on their role or department.

​

URL Parameters

You can pass data into a form via URL query parameters:

https://your-zygo-instance.com/api/forms/{node_id}?name=Jane&source=email

These are accessible in the form’s templates and in the node output under session_data:

{{1_Web Form.session_data.name}}
{{1_Web Form.session_data.source}}

This is useful for pre-filling forms from email links, embedding forms with context, or tracking where submissions come from.

​

Rate Limiting

Public form endpoints are rate-limited to 5 requests per second to prevent abuse. This applies to both viewing and submitting the form.
