Overview
CommBox integrates with the WhatsApp Business Platform (API), enabling businesses to manage WhatsApp conversations through agents, automation, and AI.
WhatsApp offers three products:
WhatsApp Messenger – The standard WhatsApp app for personal communication between individuals.
WhatsApp Business App – For businesses communicating directly with customers through a mobile app.
WhatsApp Business Platform (API) – For businesses that integrate WhatsApp with customer engagement platforms such as CommBox for centralized customer communication, automation, AI Agents, and advanced conversation management.
This guide covers two installation methods for connecting WhatsApp to CommBox:
WhatsApp Business with Coexistence – Connect an existing WhatsApp Business app number while continuing to use the app alongside CommBox. This method requires a new WhatsApp Business Account (WABA).
New WhatsApp Number – Register a new number directly with the WhatsApp Business Platform.
Select the installation method that matches your current WhatsApp setup and follow the corresponding instructions.
Out of scope: This guide does not cover WhatsApp Business Migration – transferring an existing WhatsApp Business app number to the WhatsApp Business Platform without retaining access to the app. Businesses may choose this method to use capabilities unavailable with Coexistence, such as WhatsApp Groups, subject to Meta’s eligibility requirements.
WhatsApp Business with Coexistence
WhatsApp Coexistence lets businesses connect their existing WhatsApp Business app number to the WhatsApp Business Platform (API) while keeping the same number in the WhatsApp Business app.
With Coexistence, businesses can continue communicating with customers through the mobile app while using CommBox to manage conversations, automate responses, and provide AI-powered customer service.
Supported messages sync between the two environments, letting businesses keep their existing WhatsApp communication while adding CommBox capabilities.
Prerequisites
Before connecting your WhatsApp Business app to CommBox, make sure you have:
An active WhatsApp Business app account – The business phone number must already be registered and actively used in the WhatsApp Business app.
An updated WhatsApp Business app – Install the latest available version on your smartphone.
Access to the smartphone – You will need the phone running the WhatsApp Business app to authorize the connection and scan a QR code.
An active Facebook account – Use a genuine personal Facebook account with the appropriate permissions to manage the business assets. Avoid fictitious accounts or accounts created solely for onboarding.
A Meta Business Portfolio – You must have permission to select or create the business portfolio used for the integration.
A valid email address – Used for business account information and related communication.
Accurate business information – Your business details must be genuine and verifiable by Meta.
For more information about business verification, see Meta's Business Verification documentation.

Enter a name for the channel, select the new WA phone number you just added, select ownership, add sub-channels (optional), and click Create Channel.

Note: It may take approximately one hour for the newly connected number to appear in the list. Once the channel is created, it opens in CommBox and is ready for configuration.

At any time, click the Edit icon (a document with a gear) to change the channel name, add subchannels (each with unique channel settings), or change the channel’s ownership. Subchannels can have their own settings but cannot have different ownership from the main channel.
Next Step
Your WhatsApp Business app number is now connected to CommBox through the WhatsApp Business Platform.
You can continue using the WhatsApp Business app while managing supported WhatsApp conversations through CommBox.
Important: Meta may disconnect the WhatsApp Business Platform connection if the WhatsApp Business app on the primary phone remains inactive for approximately 14 days. This can interrupt Coexistence and affect message delivery through CommBox. To maintain the connection, open the WhatsApp Business app on the primary phone regularly, at least once every 14 days.
To configure your channel, including agent assignments, automation, message templates, security, and other options, see the WhatsApp Channel Settings guide.
