Overview
The Wapisimo node's "Get QR Code" operation retrieves the WhatsApp QR code for a specified WhatsApp account (identified by Phone ID) via the Wapisimo API. This is typically used to initiate or re-authenticate a WhatsApp session, such as when connecting a new device or re-linking an existing one.
Common scenarios:
- Onboarding a new WhatsApp number to your automation.
- Reconnecting a WhatsApp account after logout or session expiry.
- Automating the process of fetching QR codes for user support or device management.
Example:
A business wants to automate the onboarding of customer service agents' WhatsApp numbers. The workflow uses this node to fetch the QR code, which is then sent to the agent for scanning.

}
- qr: A data URL or base64 string representing the QR code image.
