email API / mailrobot
All API commands can be executed via email templates sent to firstname.lastname@example.org. email@example.com will also be the sender email address of HEXONET´s API call answers. To send emails to the API in OT&E mode, please use firstname.lastname@example.org as recipient address. Please note that you first have to create an OT&E account before you start with testing.

Your login credentials and the API command which should be executed has to be submitted in the message body. Further you can submit some kind of transaction ID in the subject line. The HEXONET system will pass this subject to the response email.
