When using the AT&T SMS API subscribers need only a single request to broadcast messages to one or more recipients. It allows developers to integrate short code messaging capabilities in applications. The API provides the polling functionality for tracking of the delivery statuses of messages. A sender can use the poll message functionality to request callback notifications of the delivery status of sent messages. The RESTful API sends requests in URI Query String/CRUD format and returns responses in JSON format. It is offered as a premium access service that provides subscribers access to up to 1 million API call per month.
