The Flowroute Messaging API (v2) allows users to send, receive, and review SMS messages over a RESTful HTTP interface.
Authentication
Currently the Messaging API (v2) only supports HTTP Basic Auth; however, OAuth 2.0 implementation is planned for the future. Use your API credentials from Flowroute Manage to authenticate: Access Key serves as your username while Secret Key serves as your password.
Versioning
Messaging API (v2) is a major version bump from the Flowroute API v1.
