New SMS/MMS Received
Overview
Use this instant trigger when a RingCentral extension receives a new SMS or MMS message. The trigger can return message metadata, message text, and sender and recipient fields.
RingCentral admins can monitor up to 50 selected extensions with one Zap. Non-admin users can only subscribe to SMS/MMS messages for their own extension. If the connected user is not an admin, a warning is shown during configuration.
