You can migrate an existing number to WhatsApp Business API, but it will disconnect from the regular WhatsApp or WhatsApp Business App. Many businesses use a dedicated number for their business account.
How much does WhatsApp Business API cost?
WhatsApp charges per conversation (not per message), with pricing varying by country and conversation type. Through platforms like Dewx, you typically pay a subscription that includes a conversation allocation.
Can multiple team members use the same WhatsApp number?
Yes, with WhatsApp Business API through a platform like Dewx. The basic WhatsApp Business App is limited to one device (plus web companion).
Is WhatsApp Business HIPAA compliant?
The standard WhatsApp Business API is not HIPAA compliant. Healthcare businesses should consult with compliance experts before using WhatsApp for patient communication.
How do I migrate from WhatsApp Business App to API?
Most solution providers offer migration assistance. You'll port your number, verify your business, and set up the API integration. Conversation history from the app doesn't transfer automatically.
