n8n + Formspring: send form submissions in real time
n8n is the open-source automation platform of choice for teams that want Zapier-style workflows without sending data through a third-party service. Formspring + n8n is a clean fit - Formspring fires a signed webhook, n8n catches it and runs your workflow on your own infrastructure. Self-host both for end-to-end EU data residency.
Setup in 5 steps
- In n8n, create an incoming webhook URL (or equivalent) and copy it.
- In Formspring, open your form → Webhooks → Add webhook → paste the URL.
- Pick events to deliver (default: every successful submission).
- Save and send a test submission. The Formspring delivery log shows the response.
- Verify HMAC signatures in n8n (or your relay) using
X-Formspring-Signature: t=…,v1=….

}Why connect n8n to Formspring
Real-time form notifications without polling. The moment a submission lands, n8n hears about it via signed webhook. Replace email-based form alerts with structured channel notifications, threaded conversations, or programmatic workflow triggers.
Reliability and retries
Formspring retries failed deliveries with exponential backoff (5 attempts over 24 hours). Every attempt is logged in the dashboard with response code, latency, and body. Use the Replay button to re-fire any past delivery.
Security: HMAC signing
Every webhook request to n8n (or your relay) carries an X-Formspring-Signature: t=<timestamp>,v1=<sha256-hmac> header. Verify in 3 lines (constant-time compare) to confirm the request came from Formspring and wasn't tampered with.
Custom payload shape
On Pro+ plans, you can transform the payload before delivery - pick fields, rename them, add static metadata, or filter by spam score. Useful when n8n's expected shape doesn't match Formspring's default.
