The Vonage Messages v1 API has been promoted to General Availability status, and its implementation in the server SDKs is being worked on by the Developer Relations Tooling Team. The goal is to ensure each SDK feels idiomatic, with a focus on consistency and correctness. The Java SDK's implementation of the Messages API is discussed, including the data model, validation logic, and builder pattern used to emulate named arguments. The design aims to prevent invalid message construction, making it difficult to "misuse" the API, while still allowing for easy discoverability and usage through a strongly typed language like Java. This approach provides a better user experience compared to using the API directly with tools like cURL, which requires manual knowledge of the schema and can be error-prone.
