Integrations

Integrations are on the Starter plan and up; Klaviyo, Mailchimp, Omnisend and HubSpot need Pro. Every delivery to an integration is logged in the Delivery Log with retries.

Open Integrations, click Connect on a destination, fill in its details, choose the forms it applies to (or all forms), and click Connect. Use Send test to send a sample submission. Pause stops deliveries without removing the connection.

Per form, the editor's Integrations tab lets you switch any destination on or off.

Chat

Destination	What you need
Slack	An incoming webhook URL for the channel
Discord	A channel webhook URL
Microsoft Teams	A workflow or incoming webhook URL
Telegram	A bot token and the chat ID

Each submission is posted as a message with the form name, reference, answers and a link to the submission.

Spreadsheets and databases

Destination	What you need
Google Sheets	Connect your Google account and pick the spreadsheet; one row per submission
Airtable	A personal access token, base ID and table

Email marketing and CRM (Pro)

Destination	What happens
Klaviyo	The profile is created or updated and subscribed to the list you choose
Mailchimp	The submitter is added to an audience
Omnisend	The submitter is added as a contact
HubSpot	The contact is created or updated and the answers are logged as a note

Zapier, Make and n8n

1. In your tool, create a webhook trigger and copy its URL. Zapier: Webhooks by Zapier, Catch Hook. Make: Webhooks, Custom webhook. n8n: Webhook node, POST.
2. In Form Expert, Integrations, choose the tool, paste the URL, pick the forms, Connect.
3. Click Send test so the tool learns the payload and you can map fields.

Custom webhook

Webhook (custom) posts JSON to any HTTPS endpoint. Set a signing secret to verify calls.

Payload:

{
  "event": "submission.created",
  "version": 1,
  "delivery_id": "…",
  "attempt": 1,
  "shop": "your-store.myshopify.com",
  "form": { "id": "a8xykg4u7c", "name": "Contact us" },
  "submission": {
    "ref": "FX-AB12CD",
    "id": "…",
    "received_at": "2026-08-28T10:00:00.000Z",
    "email": "[email protected]",
    "customer_id": "gid://shopify/Customer/123",
    "page_url": "https://your-store.com/pages/contact",
    "attribution": { "utm_source": "newsletter", "utm_campaign": "spring", "referrer": "https://news.example", "landing_page": "https://your-store.com/?utm_source=newsletter" },
    "data": { "name": "Ada", "email": "[email protected]", "message": "Hi" },
    "fields": [{ "key": "name", "label": "Name", "type": "text", "value": "Ada" }],
    "files": [{ "id": "…", "filename": "photo.jpg", "size": 12345, "mime": "image/jpeg" }]
  }
}

Headers: Content-Type: application/json, X-FormEx-Event: submission.created, and with a secret, X-FormEx-Signature: t=<unix seconds>,v1=<hex>.

Verify: v1 is HMAC-SHA256 of "<t>.<raw body>" with your secret. Reject calls whose t is older than five minutes or whose signature does not match.

const [t, v1] = sig.split(",").map((p) => p.split("=")[1]);
const expected = crypto.createHmac("sha256", SECRET).update(`${t}.${rawBody}`).digest("hex");
const ok = crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(v1)) && Math.abs(Date.now() / 1000 - Number(t)) < 300;

Non-2xx responses are retried with backoff. Persistent failures raise an alert.
