2. REGISTER - Activates Your Phone Number for Messaging

What Does It Do?

Register officially activates your business phone number with WhatsApp's Cloud API so you can send and receive messages. It also displays your message limits on the dashboard.

When Should You Click Register?

Use Register when:

New Account Setup:

• You just created your WhatsApp Business account
• You're setting up Cloud API for the first time
• You need to enable your business phone number for sending messages
• You want to activate two-step verification (recommended for security)

Message Limit Issues:

• You can't see message limits on Pabbly chatflow dashboard
• Everything is connected but no limit shows up
• You've completed all requirements but still can't send messages

Display Name Change:

• You changed your display name in WhatsApp Manager
• The name change was approved by Meta
• You need to re-register the number with the new name

Before Clicking Register

Make sure ALL of these are complete:

For New Setup:

• ✅ Business phone number ownership is verified
• ✅ Two-step verification is enabled (recommended)
• ✅ Phone number is ready to use with Cloud API

For Existing Numbers:

• ✅ WABA Status: Connected
• ✅ Display Name: Approved
• ✅ Business: Verified
• ✅ Payment: Added
• ✅ GST: Added (if applicable)
• ❌ Message Limit: Missing (this is what we're fixing!)

For Name Changes:

• ✅ New display name request filed in WhatsApp Manager
• ✅ Name change approved by Meta

How to Use Register

1. Click Register API button
2. Wait 2-3 minutes
3. Refresh page
4. Send ONE test message to your number (to activate limits)
5. Verify limits appear

Why send a test message? Sending a message "wakes up" the system and makes Meta show your limits.
