Email endpoints

Email endpoints allow you to send emails to your users by doing a POST request to our service. These are created under the project view.

To be able to send emails you need to add an email configuration to your project - the configuration is stored as a JSON with your email provider settings. RESTED_DEV uses nodemailer internally, the provided options need to be compatible with nodemailer transporter. This is done in the project view, under configuration.

The email endpoint also supports GET requests to read the emails sent, and DELETE requests requests to delete emails. It does not support PUT requests as the data stored for emails cannot be modified.
