How to Send WhatsApp Messages with Ruby on Rails

In a comprehensive tutorial, Benjamin Aronov, a developer advocate at Vonage, guides readers through the process of sending WhatsApp messages from a Ruby on Rails application using the Vonage Messages API. The tutorial, published in December 2025, explains the prerequisites, such as having Ruby and Rails installed, a verified WhatsApp Business Account, and a Vonage API account. It details the creation of a new Rails application, the setup of a WhatsAppMessage model, and the configuration of a Vonage application.
