Webhooks overview

Webhooks forward every (non-spam) submission to one or more HTTPS endpoints — Slack channels, Discord servers, Zapier or n8n workflows, your own backend, or any service that accepts a JSON POST. Webhooks are configured per form from the dashboard, no code changes required.

How it works

When a visitor submits a form, SaveForm stores the submission and fans it out to every webhook you have configured for that form. Each delivery is independent — one failing receiver cannot block another.

  • Triggered on every non-spam submission by default. Test fires are available at any time from the webhook card.
  • Each webhook picks a destination preset (Slack, Slack Workflow, Discord, Zapier, n8n, generic JSON, or custom template) with sensible defaults.
  • The editor shows a live preview of the exact HTTP request that will be sent — headers, method, body — so you can tweak the JSON template before you save.
  • Every delivery is logged with status code, response body, and timing — visible on the submission row in the dashboard.

Set one up

  1. Open your form in the dashboard and click Settings on the form card.
  2. Switch to the Webhooks tab.
  3. Click New Webhook and pick a preset (Slack, Slack Workflow, Discord, Zapier, n8n, generic JSON, or custom template).
  4. Paste the destination URL. The right pane shows the live preview — adjust the JSON template, field rename map, or auth until it looks right.
  5. Save, then click Test on the webhook card to fire a sample payload and confirm the receiver accepts it.

Dive deeper

Destinations & presets

Slack, Discord, Zapier, n8n — plus generic JSON and a fully custom template.

Templates & variables

Raw vs. template mode, placeholder syntax, and the built-in helpers.

Authentication

Bearer, API key header, Basic auth, and extra custom headers.

Delivery & retries

Failures, manual retries, and the Test button.

Spam & plan limits

Webhooks never auto-fire on submissions flagged as spam. If a submission was misclassified, open it in the submissions table and click Send anyway — the webhook will fire as a manual delivery. If you genuinely want spam to flow through (for example to a quarantine endpoint), toggle “Also forward submissions flagged as spam” on the webhook.

For more context on where the _isSpam flag comes from, see Spam protection.
