  title: Dyspatch Blocks Voice Templates API
  description: '# Introduction


    The Dyspatch API is based on the REST paradigm, and features resource based URLs with standard HTTP response

    codes to indicate errors. We use standard HTTP authentication and request verbs, and all responses are JSON formatted.

    See our [Implementation Guide](https://docs.dyspatch.io/development/implementing_dyspatch/) for more details on

    how to implement Dyspatch.
