General

The OpenLM system is arranged in a star formation, with the OpenLM Server in its hub. The OpenLM Server interfaces the main user interface, the EasyAdmin web application via HTTP requests. These request messages are sent using the POST method. The request & response message format is XML text.

OpenLM has released a set of open APIs for users who wish to apply the capabilities embedded in the OpenLM software for use in their own applications. These APIs may accommodate querying of the license management system for current and historical license usage, querying available licenses’ status, and license report management.

Message format

The message URL format is:

http://<OpenLM Server>:<Requested port>/OpenLMServer/

OpenLM Server: The OpenLM Server name

Requested port: This is the same port number as defined in the OpenLM Server configuration form, for all user interface requests. Its default value is 7014. See the image below for clarification.

 

The date format in XML requests & responses is a numeric value, which consists of the

number of milliseconds since 1.1.1970. Date values are always in UTC time zone.

User interface requests
