This tutorial will help you if WhatSender does not detect WhatsApp Web, does not connect correctly, or seems to stay waiting for the connection.
Before you start, it is important to understand the difference between two things:
- Linking your phone with WhatsApp Web.
- Connecting WhatSender with WhatsApp Web.
First, you must link your phone with WhatsApp Web on your computer. After that, WhatSender will be able to work with that open WhatsApp Web session.
Important: WhatSender does not work with the WhatsApp desktop app
WhatSender works with WhatsApp Web from the browser, not with the WhatsApp desktop application.
If you have the WhatsApp desktop app installed on your computer, do not use it to work with WhatSender.
To avoid conflicts, you must uninstall it before using the extension.
You must use WhatsApp from this web version: https://web.whatsapp.com

Step 1: link your phone with WhatsApp Web
Before opening WhatSender, make sure your phone is correctly linked with WhatsApp Web.
To do this:
- Open Google Chrome.
- Go to: https://web.whatsapp.com
- Scan the QR code with the WhatsApp app from your phone.
- Wait until your chats load on your computer.
If you cannot scan the QR code, WhatsApp Web does not load, or your phone does not link correctly, check the official WhatsApp tutorial.
This step depends directly on WhatsApp, so WhatSender cannot resolve issues related to scanning the QR code or linking your phone.
Step 2: open WhatSender after WhatsApp Web has loaded
Once WhatsApp Web is open and you can see your chats, open WhatSender.
It is important that WhatsApp Web is fully loaded before trying to use the extension.
If you open WhatSender before WhatsApp Web finishes loading, the extension may not detect the session correctly.
Step 3: refresh the connection between WhatSender and WhatsApp Web
If WhatsApp Web is already open, but WhatSender does not detect it or does not connect correctly, refresh the WhatsApp Web page.
To do this:
- Make sure you are on the tab where WhatsApp Web is open.
- Click the browser refresh button or press Ctrl + R on Windows / Cmd + R on Mac.
- Wait for WhatsApp Web to load again.
- Open WhatSender again.
- Try sending again.

Step 4: make sure you are using Google Chrome
WhatSender is a Chrome extension, so you must use it from Google Chrome or from a browser compatible with Chrome extensions.
We recommend using an updated version of Google Chrome to avoid compatibility issues.
Still need help?
If WhatSender still does not connect with WhatsApp Web after following these steps, we can review your case individually.
To help you better, we need you to send us a video showing the problem. Without a visual reference, it is difficult to identify what is going wrong.
In the video, we need to clearly see:
- How you import or copy the contacts into WhatSender. It is important that the numbers are clearly visible.
- How your Profile tab is configured. Please scroll down so we can see the full configuration.
- How you write and configure the message before sending it.
- What happens during the sending process in the History tab. This tab must be open and visible, not minimized.
- It is also important that, if you are using attachments, we can see how you upload them and what type of file you are sending.
To record the video, you can use a free tool such as Loom. Here is the tutorial with the instructions
Before sending us the video, please review it. If you cannot clearly see the extension, the numbers, and the actions you are taking, we will not be able to see them clearly either. With a clear and complete video, we will be able to better identify the error and help you find a solution.
Then, send us the video through our contact form: contact support.
Our team will review your case and reply within approximately 1 to 2 business days, Monday to Friday.
