Lead Enrichment with WhatsApp Profile Data
Capture a phone number, enrich it with WhatsApp profile fields in < 300 ms, and drop the enriched record straight into your CRM. Works for web forms, Zapier, Make, n8n, and custom server-side integrations.
The workflow
- User submits a phone number on a lead form.
- Your backend calls GET https://whatsapp-proxy.checkleaked.cc/number/{number} with header x-rapidapi-key: <direct-purchase-key> within the same request cycle (or use the RapidAPI marketplace base + key + host header).
- Response fields are merged into the CRM record: about/status text, profile picture URL, business-account flag.
- Downstream automation (lead scoring, routing to AE vs self-serve) branches on the business flag.
Which fields boost lead quality
- isBusiness — strongest B2B qualifier. Route business accounts to sales.
- about — WhatsApp status text. Often confirms job title or company.
- profilePic — visible face in the CRM. Anecdotally improves rep response rate.
- isWAContact: false — signal to check spelling, fallback to SMS/email, or deprioritise.
Volume & pricing guidance
Most lead-gen workflows fit comfortably in the PRO tier ($35/mo, 10,000 lookups). High-volume SaaS or performance-marketing shops typically sit on ULTRA ($139/mo, 50,000). Agencies that enrich client lists at scale should consider MEGA ($449/mo, 500K at $0.005 per lookup) or Pay-As-You-Go crypto credits ($40 per 50K) for one-off projects.
No-code integration examples
Zapier: "Webhook by Zapier — GET" action → parse JSON → map into CRM update step.
Make.com: HTTP module with x-rapidapi-key header (direct key) → iterator over JSON fields.
n8n: HTTP Request node → Set node for field mapping → downstream CRM node.
Google Sheets: Apps Script UrlFetchApp with x-rapidapi-key header in the trigger.
