Guide/SendApp Cloud/Getting started
Connect a WhatsApp number via QR
SendApp Cloud connects your WhatsApp number by scanning a QR code, just like WhatsApp Web does. It doesn't use Meta's official API: it's designed for transactional and operational messages from your number. Here we'll see how to connect it and what to do if something goes wrong.

Before you start
- A SendApp Cloud account
- A phone with WhatsApp active on the number to connect
Adding an account
- 1
Open WhatsApp from the menu
Go to the WhatsApp/Account section and click “Add account”.
- 2
Wait for the QR
A QR code is shown. It regenerates automatically every ~45 seconds for security.
- 3
On your phone, open Linked devices
WhatsApp → Settings → Linked devices → Link a device.
- 4
Scan the QR
Point the camera at the QR shown by SendApp.
- 5
Wait for the connection
The status switches to “Connected” and the account is ready to use.
Keep your phone on and online: like WhatsApp Web, the connection uses the phone as a reference. If it stays offline for a long time, the account can disconnect and you'll need to scan the QR again.
Common errors and solutions
- Conflict with another session
- If a conflict error appears, another WhatsApp Web/Desktop session is interfering. On your phone open Linked devices, log out of the ones you don't recognize, wait for the timer, and try again.
- “Waiting for this message” on the recipient's phone
- This can happen after a reconnection: use the session key reset feature (for a specific number or for all of them) to fix it.
- The QR regenerates before you can scan it
- This is normal (every ~45 seconds). Keep your phone ready and scan it as soon as it appears.
