Whatsapp Check API
Check whether an Indian mobile number is registered on WhatsApp and whether it is a personal or business account, before you message a customer.

What the Whatsapp Check API does
Whatsapp Check reports whether a mobile number has an active WhatsApp registration and distinguishes a personal account from a business one.
If WhatsApp is a channel you use for onboarding or support, this tells you in advance whether a number can be reached that way, so you can route to SMS instead of discovering the failure after sending.
Where teams use the Whatsapp Check API
Confirming reachability before starting a WhatsApp KYC journey
Routing communication between WhatsApp and SMS
Identifying business accounts among merchant contacts
Cleaning a contact list before a messaging campaign
Frequently Asked Questions (FAQs)
Does it reveal anything personal?
No. It reports registration status and account type only, not profile details or messages.
Why does the business distinction matter?
Business accounts behave differently for messaging, and for merchant onboarding a business account is a mild positive signal about the contact.
Does registration prove the customer controls the number?
No. Use mobile number verification with an OTP to establish control.
