Creates an SMS event subscription. A webhook_id is required so that we know to which url the events shall be sent. An SMS direction is also required in order to limit the direction for which SMS events are sent. Use 'all' to get SMS events for all directions. A target_type and target_id may optionally be provided to scope the events only to SMS to/from that target.
See https://developers.dialpad.com/docs/sms-events for details on how SMS events work, including the payload structure and payload examples.
NOTE: To include the MESSAGE CONTENT in SMS events, your API key needs to have the "message_content_export" OAuth scope for when a target is specified in this API and/or "message_content_export:all" OAuth scope for when no target is specified.
NOTE: See https://developers.dialpad.com/v1.0-archive/reference for APIs that can operate on subscriptions that were created via the deprecated APIs.
