SDKs & tools
whatsapp-checker is the official TypeScript SDK for the WhatsApp Data API. It wraps the profile endpoint with a typed client, automatic rate-limit handling, retry-with-backoff, and bulk helpers so you don't have to reimplement the plumbing.
This is the recommended starting point for a new TypeScript or Node.js integration — install it, pass your key, and call check(number).
Endpoints it uses
GET /number/{phone} — typed response with presence and profile fields.
Bulk + rate-limit + retry helpers built in.
The same call
