Easily integrate your application with MailUp using our new REST API. Many of the tasks that can be performed in the MailUp admin console can now be executed also through the REST API, giving you remote and flexible access to many of MailUp's great features.
Please note that the REST API is not designed for sending transactional emails. You can easily send transactional emails through your MailUp account by leveraging MailUp's built-in SMTP relay system, at no extra charge.

Integrating your application
A few things to keep in mind:
The MailUp REST API uses Oauth2 and requires a token refresh. You can use the available samples to see how to refresh the authorization token
By properly setting the request header you can set the response format as JSON or XML
Each application is tied to a set of application keys, which are used to authorize the application (get yours).
- Users of the application will be authenticated using their own MailUp account credentials.
- The application keys used in the sample code shall not be used in a production environment.
