By implementing this interface, you can define custom tabs on the object or request page. A custom tab can view any web content displayable in an iframe tag. For an example, see the ShowRequesterAddress application template.

In the application create a new script using the IElementTab template and name it appropriately according to the content of the tab. In the newly created script, set the following properties in the constructor of the class:

  • Id - a unique tab identifier (string)
  • Entity - the type of entity for which the tab will be displayed (Entity.Request or Entity.Object).
