In this article, we’ll learn how to buy a phone number and send an SMS text message using Twilio's Postman Collection and a Postman Environment. Luckily, visual API development tools such as Postman make the learning journey much easier!Īs part of Twilio’s rollout of its OpenAPI specification, we now provide a Postman collection which you can use to visually explore and interact with Twilio’s API without writing code. Learning how to use a 3rd party API can be a difficult task. If you've identified a mismatch between Twilio's API behavior and the specification, please open an issue. The spec is expected to be accurate, but is currently in active development and is unsupported. The Twilio OpenAPI Spec is currently in BETA.
