Welcome to the guide for WhatsApp Blocklist Management! This feature allows you to manage your WhatsApp blocked contacts directly from the app. You can view who you’ve blocked, add new contacts to your blocklist, and unblock contacts when needed — all without opening WhatsApp manually.

1. Getting Started

Before you can manage your blocklist, you need to connect the app to your WhatsApp account. This is a safe, one-time connection process similar to using WhatsApp on your computer.

Opening Blocklist Management

1. Open the App: Launch the WB Sender app on your phone.
2. Navigate to Blocklist: Find and tap on the “Blocklist Management” or “Block List” option in the menu.
3. Wait for Initialization: The app will start preparing the connection. You’ll see a “Connecting…” message while it gets ready.

2. Connecting Your WhatsApp Account

You have two ways to connect your WhatsApp account: using a Pairing Code (recommended) or scanning a QR Code.

Option A: Using Pairing Code (Easiest)

1. Enter Your Phone Number: Type your phone number with country code (e.g., +1 for USA, +91 for India). Make sure to include the “+” sign at the beginning.
2. Request Code: Tap the “Request Code” button. Wait a few seconds for the app to generate your unique pairing code.
3. Copy the Code: A 8-digit code will appear on screen (like “1234-5678”). Remember or note down this code.
4. Open WhatsApp on Your Phone:
   • Go to Settings (gear icon)
   • Tap Linked Devices
   • Tap Link a Device
   • Choose “Link with phone number instead”
   • Enter the 8-digit pairing code when prompted
5. Success! Once linked, the status will change to “Connected” and you’re ready to manage your blocklist!

Tip: Pairing code is easier because you don’t need to scan anything with your camera!

Option B: Using QR Code

1. Tap “Show QR Code”: After the app initializes, tap the button to display a QR code.
2. Wait for QR Code: A scannable QR code will appear on your screen.
3. Open WhatsApp on Your Phone:
   • Go to Settings (gear icon)
   • Tap Linked Devices
   • Tap Link a Device
4. Scan the Code: Point your phone’s camera at the QR code shown in the app.
5. Success! The status changes to “Connected” when the scan is successful.

3. Viewing Your Blocked Contacts

Once connected, the app automatically loads your current blocklist. Here’s what you’ll see:

• Blocked Contacts List: All your blocked contacts appear in a scrollable list.
• Contact Count: At the top, you’ll see the total number of blocked contacts (e.g., “3 contacts”).
• Empty State: If you haven’t blocked anyone, you’ll see a message saying your blocklist is empty.

Refreshing the List

To make sure you’re seeing the latest information:

1. Tap the “Refresh” button.
2. The app will fetch the current blocklist from WhatsApp.
3. The list updates with any recent changes.

4. Blocking New Contacts

Want to add someone to your blocklist? It’s easy!

Steps to Block Contacts

1. Tap the Add Button: Look for the round floating button (usually with a “+” icon) at the bottom of the screen.
2. Select Contacts: A contact picker opens showing all your phone contacts.
3. Choose Who to Block: Tap on one or more contacts you want to block. Selected contacts will be highlighted.
4. Confirm Selection: Tap “Done” or the checkmark to confirm your selection.
5. Processing: The app will add each selected contact to your WhatsApp blocklist. You’ll see a confirmation message.
6. Done! The newly blocked contacts appear in your blocklist.

Note: You can select multiple contacts at once to block them all together!

5. Unblocking Contacts

Changed your mind about someone you blocked? Here’s how to remove them from your blocklist:

1. Find the Contact: Scroll through your blocklist to find the person you want to unblock.
2. Tap on Their Entry: Tap on the blocked contact’s name or number.
3. Confirmation Popup: A message will appear asking “Are you sure you want to unblock this contact?”
4. Confirm Unblock: Tap “Unblock” to confirm, or “Cancel” if you changed your mind.
5. Done! The contact is removed from your blocklist and can now message you again.

Success: Once unblocked, the person can send you messages and see your profile picture and status again.

6. Understanding Connection Status

The app shows different colored indicators to help you understand the connection status:

• ● Orange/Yellow: The app is connecting or waiting for you to scan the QR code / enter pairing code.
• ● Green: Successfully connected! You can now manage your blocklist.
• ● Red: Connection error or not connected. Try reconnecting.

7. Troubleshooting Tips

“Connection Error” Message

• Make sure your phone has an active internet connection (WiFi or mobile data).
• Tap the “Retry” button when prompted.
• If problems persist, try closing and reopening the app.

QR Code Expired or Not Loading

• QR codes last for about 3 minutes. If expired, tap “Show QR Code” again to get a new one.
• Make sure the app has fully initialized before requesting the QR code.
• Try using the Pairing Code method instead — it’s often more reliable.

Phone Number Errors

• “Enter phone number”: You left the phone number field empty.
• “Must start with +”: Add your country code with a “+” sign (e.g., +1, +44, +91).
• “Invalid format”: Check that your phone number has the correct number of digits (usually 10-15 digits total including country code).

Session Expired / Disconnected

• If you see “Restoring session…”, wait a moment. The app is trying to reconnect automatically.
• If reconnection fails after 3 attempts, you’ll see a popup with “Retry” and “Troubleshoot” options.
• Tap “Troubleshoot” for additional helpful tips.

Can’t Add or Remove Contacts

• Make sure you’re connected (green status indicator).
• If you see “Not authenticated”, you need to reconnect your WhatsApp account first.
• Check your internet connection and try again.

8. Important Notes

What Happens When You Block Someone?

• They cannot send you messages on WhatsApp.
• They cannot see your profile picture, status updates, or “last seen”.
• They will not know they’ve been blocked — their messages simply won’t be delivered.
• You will not receive their calls or messages.

What Happens When You Unblock Someone?

• They can message you again.
• They can see your profile picture and status.
• Messages they sent while blocked will not be delivered — those are lost.

Privacy & Safety

• Your WhatsApp connection is secure and uses the same protection as WhatsApp Web.
• The app only accesses your blocklist — it cannot read your messages or chats.
• You can disconnect your session anytime by unlinking the device from WhatsApp settings.
