Salesforce + Formspring: send form submissions in real time
Formspring posts each clean submission to Salesforce as a new Lead using the Web-to-Lead endpoint - no OAuth, no managed package, just your 18-character Org ID and an optional field map. Submission keys map directly to standard Lead fields (first_name, last_name, email, company, phone, lead_source) or to custom Lead fields by API name (Custom_Field__c). Salesforce caps Web-to-Lead at 500 submissions per org per day by default; raise it through Salesforce support for high-volume forms.
Setup in 5 steps
- In Salesforce, 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 Salesforce (or your relay) using
X-Formspring-Signature: t=…,v1=….

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