The parameters for the EsendexInboxService constructor include optional arguments for a security certificate:
EsendexInboxService( $username, $password, $accountReference, $isSecure = false, $certificate = '' )
To send via HTTPS, use the following arguements:
$isSecure = true
$certificate = "PATH TO CERTIFICATE FILE" ( e.g. C:\Windows\curl_ca_bundle.crt ).
To send via HTTP these arguments can be ignored.
The EsendexInboxService.php class allows you to retrieve your inbox messages in two ways. The GetMessages method can be used to retrieve small inboxes, the maximum number of messages that will be returned with this method is 100.
Inboxes holding more than 100 messages should use the GetLatestMessages method. This method takes two parameters, LastMessageID (this is the message IndexID) and MaxMessages. If LastMessageID is blank the latest number of messages (defined by MaxMessages), will be returned. Specify an IndexID to retrieve the messages that were received after it. MaxMessages is simply the Maximum number of messages to retrieve. This method allows you to retrieve your inbox messages in batches (an ideal batch size is around 50), which is more efficient than trying to recieve them all at once.
