API response

After a succesful request, SMTPeter sends a JSON object containing a unique identifier for every recipient that is going to receive an email.

    "id1" : "recipient1@example.com",
    "id2" : "recipient2@example.com"

The IDs that are given back can be used to acquire information about this mailing using other API methods. If you're sending email to multiple receivers with one call the return data will also contain multiple IDs with their respective recipients.

Settlement of errors

The REST API has a clear way of communicating errors. Namely, by giving back the regular HTTP error code that is being triggered. Providing wrong information doesn't matter per se as you will always receive a textual explanation of what happened. A successful call always gives you back a code between (and including) 200 and 202.
