A developer created a solution to automatically send robotic birthday messages to friends who are living abroad, using Google Sheets and Vonage's AI Studio. The solution involves creating a virtual agent that sends SMS messages with personalized birthday greetings. To achieve this, the developer uses a combination of Google Apps Scripts, Vonage API, and AI Studio, leveraging low-code and drag-and-drop interfaces. The application runs daily to check for birthdays and can be extended to send other types of notifications or even emails using additional integrations.
