      description: 'Sends an outbound SMS message to a specified recipient. This API allows for associating the message with a campaign, contact, or workitem.


        **Note on Inbound SMS:** This SDK primarily exposes APIs for *sending* SMS. Direct webhook configuration for *receiving* inbound SMS is typically handled internally by the Nextiva platform. Inbound SMS events are then consumed by the SDK as Workitems (e.g., `WorkitemTypes.InboundSMS`) via the SDK''s event stream, not through a public API for webhook configuration.
