WhatsApp Business
Connect your WhatsApp Business account to LastBot ONE to automate customer conversations, handle escalations to live agents, and unify your messaging channels in one place.
Prerequisites: A Meta Business Account, a phone number not currently registered with WhatsApp, and an active LastBot ONE subscription.
Create a Meta Business Account
You need a verified Meta Business Account before connecting WhatsApp Business to LastBot ONE.
- Go to business.facebook.com and sign in with your Facebook account.
- Click "Create Account" and fill in your business name, your name, and your business email address.
- Follow the on-screen prompts to verify your business email.
- Complete the identity verification step if prompted: this may require submitting business documents.
Set Up a WhatsApp Business App
Create a WhatsApp Business app inside the Meta Developer Portal to obtain your API credentials.
- Visit developers.facebook.com and log in with your Meta Business Account.
- Click "My Apps" → "Create App", then choose "Business" as the app type.
- Enter your app name (e.g., LastBot Integration) and select your business account.
- In the app dashboard, find "WhatsApp" under Products and click "Set up".
- Note down your App ID and App Secret: you will need these in Step 4.
Add a WhatsApp Business Phone Number
Register the phone number you want to use for customer conversations.
- Inside the WhatsApp product section, go to "Getting Started" and click "Add phone number".
- Enter the phone number and choose a verification method (SMS or voice call).
- Enter the verification code to confirm ownership of the number.
- Set a display name for the number: this is what customers will see in WhatsApp.
- Record the Phone Number ID shown on the dashboard; you will need it in Step 4.
Generate a Permanent Access Token
LastBot ONE requires a long-lived system user token to send and receive messages on your behalf.
- In Meta Business Suite, navigate to "Settings" → "Users" → "System Users".
- Click "Add" and create a new system user with the "Admin" role.
- Click "Generate New Token", select your WhatsApp app, and grant the following permissions: whatsapp_business_messaging, whatsapp_business_management.
- Copy and store the generated token securely: it will only be shown once.
Connect WhatsApp in LastBot ONE
Enter your credentials in the LastBot ONE dashboard to activate the integration.
- Log in to your LastBot ONE account and navigate to "Integrations" from the sidebar.
- Find "WhatsApp Business" and click "Connect".
- Paste your Phone Number ID, App ID, App Secret, and System User Access Token into the respective fields.
- Click "Save & Test Connection": LastBot ONE will send a test message to verify the setup.
- Once confirmed, the status indicator will turn green and the channel is live.
Configure Conversation Routing
Define how incoming WhatsApp messages are handled by your AI agents and live agents.
- In the LastBot ONE dashboard, go to "Channels" → "WhatsApp Business".
- Set up your AI agent greeting message and fallback behavior for unrecognised queries.
- Configure escalation rules so conversations are handed off to a live agent when needed.
- Enable or disable read receipts and typing indicators according to your brand preferences.
- Click "Save" to apply your routing configuration.
