Historically, a number lived in one place: migrating to the API meant giving up the app, and with it the habit of answering chats from a phone. Coexistence removes that trade-off by letting both run side by side on a single number.
In a coexistence setup, chats and contacts sync between the app and the API platform. A small team can keep replying from the familiar app while software handles campaigns, automations, and analytics on the same number.
Coexistence is rolled out through Cloud API onboarding with participating providers, and eligibility depends on the number and the market. Some capabilities remain specific to one side, so it is worth checking current limitations before connecting.
