HTTP API - 'receivemessage' action
This action can be used to receive SMS messages from the SMS Gateway using HTTP polling. HTTP polling means that you download SMS messages from the inbox folder of the gateway like you would download a webpage. In this section you can get information about how you can use the receiveimessage action, what are the parameters, and you will be presented with an example HTTP request to download incoming messages.
To download incoming text messages use the following URL format:https://127.0.0.1:9508/api?action=receivemessage&username=UUUUU&password=PPPPP&
For 127.0.0.1, you should substitute the host name or the IP address of the computer your SMS gateway is installed on. The port number 9508 is the default HTTP port number of the Ozeki SMS gateway. It port number can be configured in the user interface of Ozeki 10 SMS Gateway, by clicking on the Advanced button in the toolbar.
The username and the password should be substituted for "UUUUU" and "PPPPP". The username and password identifies the user you have created in the SMS gateway. When you invoke the receivemessage action by calling the URL, you will download messages from the inbox of the user specified in the query with the username and the password.
The folder parameter of the message should be set to inbox.
The limit parameter specifies the number of messages that will be downloaded. It is recommended to download less then 1000 messages in a single request. You can download the remaining messages in subsequent requests.
The afterdownload parameter can be used to remove messages from the SMS gateway once they have been successfully downloaded.
Example URL Request
