Coexistence allows you to use the same WhatsApp Business number in two places in parallel: in the WhatsApp Business application on your advisor's phone, and in Alcmeon via the WhatsApp Cloud API.

All conversations are synchronized in Alcmeon: incoming messages from customers, replies sent by the agent from their phone, and replies sent from Alcmeon. The "WhatsApp Business App" channel is separate from your existing WhatsApp Cloud API channel: it has its own accounts, rules, and statistics.

This mode is particularly suited to clienteling and 1-to-1 customer relations, where the advisor maintains the proximity of their mobile application while the company retains the history and control.

Functional scope

The WhatsApp Business App channel benefits from the same functional scope as the standard Alcmeon WhatsApp channel . Everything your teams already do on WhatsApp applies to this channel, without anything to relearn: receiving and processing conversations, replying from Alcmeon and favorite replies, sorting rules, bot scenarios, satisfaction surveys, analytics and filters, CRM connectors and exports/APIs.

In addition, this channel brings its own unique capability: the responses sent by the advisor directly from his phone are also synchronized and recorded in Alcmeon.

Differences from the standard WhatsApp channel

The perimeter is identical, with a few differences that are useful to know:

• Replies from the phone (specific to Coexistence): messages sent by the advisor from their application are sent up to Alcmeon - which is not possible with the standard WhatsApp channel.
• Marketing campaigns : not available on WhatsApp Business App accounts.
• WhatsApp Business user statistics : If multiple people share the same WhatsApp Business application (Meta allows up to 5 users), then for replies sent from a phone, the sender's identity is not transmitted by Meta; therefore, individual tracking is not available for these messages (overall volume and delivery times remain). However, when you connect a WhatsApp Business account, we automatically create a generic account containing the phone number and name displayed in the WhatsApp Business application. Messages sent by the agent from their phone will be automatically linked to this generic user, which you can find in the various "Action Author (details)" sections of the statistics pages.

These differences stem from how Coexistence works on the Meta side. All technical constraints and limitations are detailed on the "Functioning and Limitations" page.
