Zapier Integration

Send form data to a Zapier webhook to trigger any Zap.

Action type: zapier Class: Core_Forms\Actions\Zapier Source: src/actions/class-zapier.php

Setup

  1. In Zapier, create a new Zap.
  2. Choose Webhooks by Zapier as the trigger.
  3. Select Catch Hook as the event.
  4. Copy the Webhook URL (starts with https://hooks.zapier.com/hooks/catch/...).
  5. In WordPress, edit your form > Actions tab > Add Action > Send to Zapier.
  6. Paste the Webhook URL.
  7. Submit a test form entry, then return to Zapier to map the fields in your Zap.

Settings Reference

Setting Required Default Description
Webhook URL Yes -- Zapier Catch Hook URL

Payload Format

All form fields are sent as a flat JSON object, plus metadata fields:

{
  "name": "Jane Smith",
  "email": "jane@example.com",
  "message": "Hello",
  "_form_title": "Contact Form",
  "_form_id": 42,
  "_submitted_at": "2026-04-09 10:30:00",
  "_ip_address": "192.168.1.1"
}

Metadata Fields

Field Description
_form_title Title of the form
_form_id WordPress post ID of the form
_submitted_at Submission timestamp
_ip_address Submitter's IP address

Array values (checkboxes, multi-select) are flattened to comma-separated strings.

How It Works

  1. Collects all form submission data.
  2. Flattens array values to comma-separated strings.
  3. Appends metadata fields (_form_title, _form_id, _submitted_at, _ip_address).
  4. POSTs as JSON to the webhook URL with Content-Type: application/json.
  5. The request times out after 15 seconds.
  6. Returns true on success.

Example: Send to Google Sheets via Zapier

  1. Create a Zap: Webhooks by Zapier (trigger) > Google Sheets (action).
  2. Paste the webhook URL in Core Forms.
  3. Submit a test entry.
  4. In Zapier, map the form fields to spreadsheet columns.
  5. Turn on the Zap.

Troubleshooting

  • Zap not triggering: Verify the webhook URL is correct. Test by submitting a form and checking the Zap history.
  • Missing fields: Submit a test entry after setting up the webhook so Zapier can detect the field structure.
  • Metadata prefix: All metadata fields start with _ to avoid conflicts with form field names.
