API Overview

A RESTful JSON API with predictable, resource-oriented URLs and HTTP response codes to indicate API errors.

We use built-in HTTP features, like HTTP authentication and HTTP verbs, which are understood by off-the-shelf HTTP clients.

Official client libraries available for most popular languages.


    Securely access your account by using API keys and TLS encryption.


    Mailosaur uses HTTP response codes to indicate the success or failure of an API request. We recommend writing code that can handle these different scenarios.

    Client Libraries (SDKs)

    Mailosaur has official client libraries for various languages. We recommend using our libraries to make HTTP calls to Mailosaur.
