Our Application Programming Interface (API) makes it easy for your own existing software to interact with the GreenMail email marketing system. The GreenMail API uses HTTP requests and JSON (JavaScript Object Notation) to allow integration with a wide range of languages, including PHP, Java, .NET, and many others. The bottom line—it allows for our system to connect with yours.
