A Practical Integration Architecture
- Frontend form → server endpoint → CRM API.
- Validate and normalize before sending to CRM.
- Store a safe copy for retries and reporting.
Rule: do not send raw, unvalidated form data directly to a CRM.
Fields You Should Capture (2026)
| Field | Why it matters |
|---|---|
| Name + email | Basic identity and follow-up |
| Phone (optional) | Faster sales contact |
| Company | Qualification and routing |
| Budget / timeline | Pipeline stage and priority |
| UTM + referrer | Attribution and ROI |
Examples
Example Routing Rule
- Budget ≥ $10k → route to Senior Sales pipeline
- Service = “SEO” → route to Marketing team owner
- Country = “US” → assign to US timezone rep
Example Attribution Snapshot
- utm_source: google
- utm_campaign: nextjs-services
- landing_page: /nextjs-development-company/
- referrer: https://www.google.com/
