API Response Errors
Here’s a complete list of the error codes you can receive from the API.
1: Unsupported HTTPS method
The API only supports GET, POST or DELETE, and some calls only support one or the other. This means you are trying to access an API call with an HTTPS method you can’t use.
2: Missing HTTPS GET/POST parameter
You failed to pass a parameter that was required for this API call.
3: Invalid API key
You used the wrong api_key parameter. Check that your client code is using the right API key (obtained in the Settings page).
4: Disallowed IP
You are coming from an IP address that is not allowed according to your settings. You can add the IP to the list on your Settings page.
5: Authentication failed
The sig parameter you passed was not a correct signature hash of your shared secret and the sorted alphabetical list of the other parameters. For more details on this, see API Details.
6: Invalid UTF-8 characters for field
You are passing invalid UTF-8 character as a parameter value.
9: Internal Error
Something’s gone wrong on our end. Your request was probably not saved – try waiting a moment and trying again.
11: Invalid Email
You tried to send to or access an invalid email address.
12: Unknown send_id

17: Login failure

18: Invalid time
You specified a time that didn’t make any sense to us. We are very liberal with accepted time formats (anything that PHP’s strtotime function can parse), but we recommend a standard format that includes timezone such as RFC 2822 (e.g. Sun, 22 Nov 2012 22:50:27 -0500).
