Frequently Asked Questions
Can I use both connectors simultaneously?
Yes! You can have multiple devices, some using WhatsApp QR and others using Cloud API. Each number requires its own connection.
Will I lose my chat history if I switch?
No. Our platform supports data migration when switching from WhatsApp QR to Cloud API.
Is Cloud API more expensive?
