URL Parameters

• webId

  The ID of an Element, Event Frame or Attribute, which is the base element or parent of all the stream attributes. See WebID for more information.

• time

  An AF time string, which is used as the time context to get stream values if it is provided. By default, it is not specified, and the default time context of the AF object will be used. See Time Strings for more information.

• timeZone

  The time zone in which the time string will be interpreted. This parameter will be ignored if a time zone is specified in the time string. If no time zone is specified in either places, the PI Web API server time zone will be used. See Time Zone for more information.

• nameFilter

  The name query string used for filtering attributes. The default is no filter. See Query String for more information.

• categoryName

  Specify that included attributes must have this category. The default is no category filter.
