RingCentral
RingCentral's RingEX cloud phone system comes with a developer platform whose SMS and MMS APIs send and receive texts from the account's business numbers.
Overview
RingCentral sells RingEX, a cloud phone system with calling, team chat, meetings, fax and business SMS. Its developer platform has SMS and MMS APIs that send and receive texts from the account's numbers, a message store for history, and webhooks for message events. A text can only be sent from a number assigned to the signed-in user's extension; shared company numbers can text through one designated extension. Automated, high-volume or marketing texts go through RingCentral High Volume SMS, which costs extra.
