Google Sheets + Formspring: send form submissions in real time
Every Formspring submission becomes a new row in a Google Sheet - perfect for non-technical teammates, lightweight CRM tracking, or contest/survey collection. Formspring routes through Zapier or Make for the Sheets API connection (Google's API requires OAuth, which we keep out of the core product). The relay setup takes 3 minutes and runs reliably at any volume.
Setup in 5 steps
- In Google Sheets, 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 Google Sheets (or your relay) using
X-Formspring-Signature: t=…,v1=….

}Why connect Google Sheets to Formspring
Real-time form notifications without polling. The moment a submission lands, Google Sheets 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 Google Sheets (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 Google Sheets's expected shape doesn't match Formspring's default.
