openapi: 3.0.0 info: version: '2026.06' title: Dyspatch Blocks Voice Drafts 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. ## Generating API Clients Dyspatch provides OpenAPI specifications for our API which can be used to generate API clients in various programming languages. We recommend using [OpenAPI Generator](https://github.com/OpenAPITools/openapi-generator). To download the latest OpenAPI specifications, click the Download button at the top of this page. To download a specific version, view the [changelog](https://docs.dyspatch.io/api/changelog.html) and select the desired version.
