Let your agent answer customers and send notifications on WhatsApp Business from a Link AI number.
WhatsApp connects a Link AI phone number to WhatsApp Business so your agent answers customer inquiries, sends notifications, and handles support in WhatsApp. Use it when your customers prefer to message you there.
What you can do
- Automated messaging: instant responses to customer inquiries on WhatsApp, 24/7.
- Rich media: send and receive images, documents, and voice notes.
- Agent Vision: with Agent Vision on, your agent understands images customers send.
- One inbox: manage WhatsApp conversations alongside your other channels in Inbox.
- Business profile: your agent uses your WhatsApp Business profile information to ground its responses.
Before you start
- Growth or Scale plan: WhatsApp is available on Growth and Scale.
- A phone number purchased from Link AI. See Phone Numbers & Calls.
- An agent configured in your account.
Assign the phone number to an agent (any agent) before you connect WhatsApp Business. Meta sends the verification code by SMS to that number, and it only reaches your Link AI Inbox when the number is assigned.
Connect
Assign the phone number to an agent
Open My Agents, select the agent, go to the Call tab, assign your phone number, and save. See Phone Numbers & Calls.
Connect WhatsApp Business
Open Phone Numbers, select the number, and scroll to the WhatsApp Business card. Open Step 1: Connect Account and click Connect WhatsApp Business. In Meta's Embedded Signup flow:
- Log in to your Meta account
- Select your Meta Business Account (or create one)
- Complete the WhatsApp Business Profile setup
- Grant the requested permissions
- When asked for a verification method, select SMS
The verification code appears in your Link AI Inbox and as a notification.
Turn on the WhatsApp channel
Open the agent's Deploy tab, find WhatsApp, toggle it on, and check that the phone number shows as enabled. See Channels.
You should see your agent reply in WhatsApp and the conversation appear in Inbox.
WhatsApp can take a few minutes to a few hours to become fully available after registration. This is normal Meta provisioning time.
Use it in an agent
- Get business verification. Complete Meta Business Verification for higher messaging limits and trust.
- Write a clear welcome message that says who the assistant is and how it can help.
- Watch your quality rating. WhatsApp monitors message quality, so keep replies helpful and relevant.
Troubleshooting
Verification code not received
- Check your Link AI Inbox; the code appears as a message and as a notification.
- Make sure the phone number is assigned to an agent (any agent is fine).
- Confirm you selected SMS as the verification method during Meta signup.
- Check that the phone number is active and not suspended.
- Disconnect and reconnect WhatsApp, selecting SMS verification.
WhatsApp not available hours after registration
Meta provisioning can take minutes to hours. Wait up to 24 hours, check the WhatsApp status card for the current registration status, and confirm PIN registration completed.
Cannot turn on the WhatsApp channel
The toggle shows why it's disabled:
Phone number not showing in the dropdown
Make sure WhatsApp is configured on the phone number (it has a metaWabaId), the number is assigned to the agent, and the number is active (not suspended or deleted).
Profile changes not syncing
Click Refresh on the WhatsApp card in Phone Numbers, or disconnect and reconnect WhatsApp to sync profile data.
Still stuck?
Check the WhatsApp status card for specific error messages, then contact support with your phone number ID, agent ID, a screenshot of any errors, and the steps you've completed. Meta's WhatsApp Business documentation and Business Verification guide may also help.
