Event notification is versioned for each event group. Based on your business needs, you can use different versions of event notification for different event groups.
The table below lists the available versions of event notification for each event group:
| Event Group Number | Event Group | Version(s) Available |
| 1 | Accounts | 2, 3, 3.1, 3.2, 3.3, 3.4, 3.5 |
| 2 | Orders | 2, 3.0 |
| 3 | Financial Transactions | 2, 3.0, 3.1, 3.2, 3.3 |
| 4 | Account Notifications | 2, 3.0, 3.1 |
| 5 | Usage Monitoring | 3, 3.1, 3.2 |
| 6 | Products | 3.3 |
Each version of event notification provides a different set of events and requires the applicable XSD and DTD files for that version.
You must use the correct version of the XSD and DTD files if you want to validate the data in your event notifications sent to you as XML documents. Please contact Aria Systems Customer Support if you need access to version 3 or any future new versions of event notification for a particular event group.
Please see the API documentation for more information about using the get_aria_xml_statement API call to retrieve XML statements.
