Prerequisites

For basic usage of the our API, you'll need to be registered at CM.com and have billing details set in your CM Wallet. This can be recurring billing via creditcard (self-service), or via alternative payment methods (signed business contract required).

To add additional communication channels such as WhatsApp, Viber, or RCS, you are required to add additional permissions per channel. You can review your channel permissions on your CM.com dashboard.

We're available to help if you need any support getting verified or activated for a certain channel. Should you have any questions, we kindly refer to our Help Center documents.
