variableName Filter by variable instance name.
variableNameLike Filter by the variable instance name. The parameter can include the wildcard % to express like-strategy such as: starts with (%name), ends with (name%) or contains (%name%).
processInstanceIdIn Only include variable instances which belong to one of the passed and comma-separated process instance ids.
executionIdIn Only include variable instances which belong to one of the passed and comma-separated execution ids.
caseInstanceIdIn Only include variable instances which belong to one of the passed case instance ids.
caseExecutionIdIn Only include variable instances which belong to one of the passed case execution ids.
taskIdIn Only include variable instances which belong to one of the passed and comma-separated task ids.
activityInstanceIdIn Only include variable instances which belong to one of the passed and comma-separated activity instance ids.
tenantIdIn Only include variable instances which belong to one of the passed and comma-separated tenant ids.

Valid operator values are: eq - equal to; neq - not equal to; gt - greater than; gteq - greater than or equal to; lt - lower than; lteq - lower than or equal to; like.
key and value may not contain underscore or comma characters.
sortBy Sort the results lexicographically by a given criterion. Valid values are variableName, variableType, activityInstanceId and tenantId. Must be used in conjunction with the sortOrder parameter.
sortOrder Sort the results in a given order. Values may be asc for ascending order or desc for descending order. Must be used in conjunction with the sortBy parameter.
firstResult Pagination of results. Specifies the index of the first result to return.
maxResults Pagination of results. Specifies the maximum number of results to return. Will return less results if there are no more results left.
