Get Tasks (Historic) (POST)
Queries for historic tasks that fulfill the given parameters.
This method is slightly more powerful than the Get Tasks (Historic) method because it allows
filtering by multiple process or task variables of types String
, Number
or Boolean
.
The size of the result set can be retrieved by using the Get Task Count (POST) method.
Method
POST /history/task
Parameters

Name | Description |
---|---|
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. |
