SMS is the channel available by default. Sending a message that contains rich content via SMS will result in the rich content platform creating a landing page to display your content. You will be able to customize the link that is displayed in the SMS to match your branding.
WhatsApp is now available via the Rich Content API in preview mode. Once we have registered your account as an official WhatsApp business account you can set the channels object to ["WhatsApp"]. The channels object does not currently support combining WhatsApp with RCS/SMS. Please discuss with your account manager to find out more.
RCS can be used in conjunction with SMS or as the sole channel. When used with SMS, the channels will be attempted in order and the platform will send only once to the first compatible channel. For example a request with the channel "RCS" will attempt to look up the Esendex account's RCS agent before sending. If the agent has been set up, and the recipient is capable of RCS the message will be delivered over RCS.
