Twilio has released a new helper library for the Go programming language, providing access to its APIs and tools. The library offers features such as automatic serialization/deserialization, authentication logic, Twilio API endpoints, request validation, and pagination support. It is designed to make it safer and more efficient to build with Twilio, and can be used for a variety of use cases, including sending SMS messages and responding to webhooks with TwiML. The Go library is available now and can be accessed through the Twilio website. The company chose Go as the primary language for this library due to its speed, safety, scalability, and ease of use, making it suitable for both high-level and low-level programming tasks.
