CHATTERgo connects to the WhatsApp Business Cloud API, so your AI agents can answer shoppers on the channel many of them already prefer — with the same product knowledge, order lookups, and handover to your team as on your storefront.
What you need
- A Meta Business account with business verification completed (required for a production phone number — Meta reviews typically take 1–5 business days).
- A WhatsApp Business phone number and its Phone Number ID from the Meta Business settings. Note that Meta uses the numeric Phone Number ID, not the phone number itself.
- An access token for the WhatsApp Business API. For production we recommend a System User token with the WhatsApp Business messaging and management permissions — it is not tied to a personal account, never expires, and can be revoked independently.
Connect the channel
- In your CHATTERgo dashboard, go to Integrations → Channels.
- Click Add WhatsApp.
- Enter the Phone Number ID and access token, give the channel a name, choose the AI agent that should handle it, and set the welcome message.
- Copy the webhook URL shown after connecting.
- In your Meta app dashboard, subscribe the WhatsApp product to that webhook URL, enter the verify token shown in your dashboard, and enable the message-related subscription fields.
- Send a test message to your WhatsApp number and confirm the agent replies.
Production checklist
- Complete business verification in Meta Business settings before using a real phone number.
- Submit your display name for approval — it should match your business name.
- Migrating an existing number or getting a new one both work; ownership is verified by SMS or voice call.
Keeping a healthy number
WhatsApp rates phone number quality. To keep messaging limits high:
- Message shoppers who expect to hear from you — respect opt-outs.
- Reply quickly; agents help here.
- Avoid spam-like sending patterns.
Troubleshooting
- "Invalid access token" — the token expired or was copied incorrectly.
Generate a fresh System User token (starts with
EAA). - "Insufficient permissions" — regenerate the token with both WhatsApp Business permissions included.
- "Phone number not found" — you entered the phone number; use the numeric Phone Number ID from Meta Business settings instead.
- Messages not arriving — re-check the webhook URL, the verify token, and that message subscription fields are enabled in Meta.
