Esendex APIs provide methods of sending and receiving messages with your account.
Sending
To send a message through our APIs you need an account reference, username and password. Make a call to one of our API send methods with these credentials and the details of your message and we will return a message ID. This ID is an internal reference to your message and you can use it to query the status of the message through the API or when contacting our support team.
Receiving
If you want to be able to receive messages inbound then the most common way of retrieving messages from your inbox is to use an account event handler. This is a publicly visible web service or html page that you create and it needs to handle four types of event. If you are not interested in one or more type of event you MUST still implement a method stub to accept those events as we check that your event handler has successfully received the notification.
