When connecting a WhatsApp number to our platform, you can choose between two different connection methods: WhatsApp QR and WhatsApp Business Cloud API (WABA). Each connector offers different capabilities, features, and use cases. This guide will help you understand the key differences and choose the right option for your business needs.
Overview
WhatsApp QR Connector
The WhatsApp QR connector allows you to connect your existing WhatsApp or WhatsApp Business App number by scanning a QR code, similar to how you would connect WhatsApp QR to your browser. This method creates a session that mirrors your phone's WhatsApp activity.
Key characteristics:
- Uses QR code scanning for connection
- Requires the phone to stay connected to the internet
- Works with personal WhatsApp or WhatsApp Business App numbers
- Session-based connection through a dedicated worker service

The WhatsApp Business Cloud API is Meta's official business messaging solution hosted on their cloud infrastructure. It provides enterprise-grade features and doesn't require a physical phone to stay online.
Key characteristics:
- Official Meta-hosted solution

- Professional business verification
- Advanced messaging features and higher limits
- Direct integration with Meta's infrastructure

Is it possible to delete and edit messages using the official WhatsApp API (Meta)?
No, it's currently not possible to delete or edit sent messages using the official WhatsApp Business API (Meta).
Current limitations
- Delete messages: There's no endpoint to delete already sent messages, not even the typical "delete for everyone" that exists in the app
- Edit messages: There's also no functionality to modify a message's content after it's been sent
What you can do
- Delete message templates you no longer use
- Mark messages as read
- Manage delivery status
Common workarounds
- Send a correction message: "❌ Please ignore the previous message. The correct information is..."
- Implement pre-send validations to reduce errors
- Use interactive messages (buttons/lists) to minimize free-text errors
This is a known limitation that many users have requested from Meta, but for now there's no indication they'll implement it soon. The API is more oriented toward transactional and support communication rather than casual messaging where edit/delete is more common.
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. Chat history, contacts, and media can be transferred.
Can I switch back if I don't like Cloud API?
Yes, it is possible, but you'll lose data synced in your WzapChat subscription and Cloud API-specific features like business verification, template messages, faster message delivery, no number ban risks, interactive button messages and more.
To switch back to WhatsApp QR connection, you should create a new subscription and select the QR connection mode instead of WABA connection.
Do I need a new phone number for Cloud API?
Recommended but not required. You can migrate your existing number or use coexistence mode with WhatsApp Business App.
Is Cloud API more expensive?
Yes, Cloud API has Meta's template message-based costs associated charged by Meta on top of our platform fees. However, for high-volume businesses, the advanced features and reliability often justify the additional cost.
We charge no additional fees per message processed, all messaging costs are the ones imposed by Meta, when applicable for template conversation starter messages.
For 24h support window messaging, messages are free.
