INTEGRATION · WEBHOOK

AntForms meets Webhook.

Send every submission to your own backend, signed and verified.

The AntForms generic Webhook connector POSTs the full submission payload to any HTTPS endpoint you choose, signed with HMAC-SHA256 so your backend can verify it really came from AntForms.

What teams build with Webhook

Three patterns AntForms customers ship most often, each reachable from the Integrations tab in under two minutes.

Send submissions to your own backend

Post every submission straight to your own API or database pipeline, with the full nested payload - every field, form metadata, and payment details if the form collects one.

Build integrations Zapier doesn't cover

Not locked to a single automation platform - point the webhook at any HTTPS URL you control, including internal tools and custom backends.

Verify and replay deliveries anytime

Every delivery is signed and logged, so you can verify authenticity, inspect the exact payload sent, and redeliver a failed request on demand.

02 · SETUP · 1 MINUTE

Live in 1 minute.

A few steps, under a few minutes. No code, no Zapier in the middle.

01
Open the Integrations tab
Find the Webhook card and click Add webhook.
02
Enter your endpoint URL
Paste your HTTPS destination URL and an optional description.
03
Set a signing secret
Add a secret so your backend can verify the X-Jupiter-Signature header on every request.
04
Send a test request
Confirm your endpoint receives the payload, then check the deliveries panel for status.

THAT’S IT · WEBHOOK IS LIVE

04 · HONEST LIMITS

The boundaries, named.

What the Webhook integration does not include, so you can plan around limits before they surface mid-rollout.

Up to 3 webhooks per form.
Always sends the full submission payload - there's no field mapping or custom payload template.
Deliveries stop retrying after 5 attempts; 5 consecutive failures auto-disable the webhook.
Whether webhook delivery on live submissions requires a paid AntForms plan may vary - email support@antforms.com to confirm current plan requirements for your workspace.

Open the Integrations tab, click Add webhook, paste your HTTPS endpoint URL, optionally set a signing secret, and send a test request.

Set a signing secret when you create the webhook. Every request includes an X-Jupiter-Signature header - an HMAC-SHA256 signature of the raw request body - that you can verify against your secret.

The full nested submission payload: every field value, form and session metadata, and payment details if the form includes a Payment block. There's no field mapping - it always sends everything.

The generic webhook can point at any HTTPS URL you control and signs every request with HMAC - Zapier's own trigger is locked to Zapier's domain and isn't signed. Use the webhook for your own backend, Zapier for connecting to other apps.

Up to 3.

AntForms retries automatically up to 5 times with exponential backoff starting at 60 seconds. After 5 consecutive failures, the webhook auto-disables.

Yes. Every delivery has a detail view with the full request payload and response body/status code, plus a manual redeliver button.

Connecting a webhook has no plan restriction on the connection limit itself, but delivery on live submissions may depend on your plan - email support@antforms.com to confirm for your workspace.
