The Apifonica Voice SMS Messaging API allows developers to integrate SMS sending, receiving, processing, and tracking features. It's available with a token as the authentication method and JSON format for callbacks. With the API, users may benefit from worldwide reach, Unicode characters, two-way SMS, delivery status notification in real time, and SMS concatenation. Developers can start for free and if they need additional calls, they can contact sales at firstname.lastname@example.org
Twelve APIs have been added to the ProgrammableWeb directory in categories including Messaging, Video, and Compliance. Highlights today include an API for retrieving financial data from regulatory resources and an API for detecting sentiment in customers written interactions.
