Mumara ONE has two APIs. The Sending API sends transactional email through a Bridge. The REST API manages your account: lists, contacts, broadcasts, sending domains and statistics.
Send one email through a Bridge with a single HTTPS request.
POST https://api.mumara.com/sendEmailManage your account from your own applications, with JSON in and out.
https://one.mumara.com/api/v2/The older REST API. Use it for the few operations V2 doesn't cover yet.
https://one.mumara.com/api/To send a receipt, a password reset or any other one-to-one email from your application, use the Sending API (or SMTP) with a Bridge. To add contacts, build lists, create broadcasts or read statistics, use the REST API, preferably V2.
The credentials aren't interchangeable: an API key doesn't work on the Sending API, and a One Connect Key doesn't work on the REST API.
