Queries for historic details that fulfill the given parameters. The size of the result set can be retrieved by using the Get Historic Detail Count method.

Method

GET /history/detail

Parameters

Query Parameters

Name	Description
processInstanceId	Filter by process instance id.
processInstanceIdIn	Only include historic details which belong to one of the passed process instance ids.
executionId	Filter by execution id.
taskId	Filter by task id.
activityInstanceId	Filter by activity instance id.
caseInstanceId	Filter by case instance id.
caseExecutionId	Filter by case execution id.
variableInstanceId	Filter by variable instance id.
variableTypeIn	Only include historic details where the variable updates belong to one of the passed and comma-separated variable types. A list of all supported variable types can be found here. Note: All non-primitive variables are associated with the type "serializable".
tenantIdIn	Filter by a comma-separated list of tenant ids.
withoutTenantId	Only include historic details that belong to no tenant. Value may only be true, as false is the default behavior.
userOperationId	Filter by a user operation id
formFields	Only include HistoricFormFields. Value may only be true, as false is the default behavior.
variableUpdates	Only include HistoricVariableUpdates. Value may only be true, as false is the default behavior.
excludeTaskDetails	Excludes all task-related HistoricDetails, so only items which have no task id set will be selected. When this parameter is used together with taskId, this call is ignored and task details are not excluded. Value may only be true, as false is the default behavior.
occurredBefore	Restrict to historic details that occured before the given date (including the date). By default*, the date must have the format yyyy-MM-dd'T'HH:mm:ss.SSSZ, e.g., 2013-01-23T14:42:45.000+0200.
occurredAfter	Restrict to historic details that occured after the given date (including the date). By default*, the date must have the format yyyy-MM-dd'T'HH:mm:ss.SSSZ, e.g., 2013-01-23T14:42:45.000+0200.
sortBy	Sort the results by a given criterion. Valid values are processInstanceId, variableName, variableType, variableRevision, formPropertyId, time or occurrence 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.
deserializeValues	Determines whether serializable variable values (typically variables that store custom Java objects) should be deserialized on server side (default true). If set to true, a serializable variable will be deserialized on server side and transformed to JSON using Jackson's POJO/bean property introspection feature. Note that this requires the Java classes of the variable value to be on the REST API's classpath. If set to false, a serializable variable will be returned in its serialized format. For example, a variable that is serialized as XML will be returned as a JSON string containing XML. Note: While true is the default value for reasons of backward compatibility, we recommend setting this parameter to false when developing web applications that are independent of the Java process applications deployed to the engine.

Result

A JSON array of historic detail objects. Each historic detail object has the following properties:

Name	Value	Description
id	String	The id of the historic detail.
type	String	The type of the historic detail. Either formField for a submitted form field value or variableUpdate for variable updates.
processDefinitionKey	String	The key of the process definition that this historic detail belongs to.
processDefinitionId	String	The id of the process definition that this historic detail belongs to.
processInstanceId	String	The id of the process instance the historic detail belongs to.
activityInstanceId	String	The id of the execution the historic detail belongs to.
executionId	String	The id of the execution the historic detail belongs to.
caseDefinitionKey	String	The key of the case definition that this historic detail belongs to.
caseDefinitionId	String	The id of the case definition that this historic detail belongs to.
caseInstanceId	String	The id of the case instance the historic detail belongs to.
caseExecutionId	String	The id of the case execution the historic detail belongs to.
taskId	String	The id of the task the historic detail belongs to.
tenantId	String	The id of the tenant that this historic detail belongs to.
userOperationId	String	The id of user operation which links historic detail with user operation log entries.
time	String	The time when this historic detail occurred, default format* yyyy-MM-dd'T'HH:mm:ss.SSSZ.
removalTime	String	The time after which the historic detail should be removed by the History Cleanup job. Default format* yyyy-MM-dd'T'HH:mm:ss.SSSZ.
rootProcessInstanceId	String	The process instance id of the root process instance that initiated the process containing this historic detail.

* For further information, please see the documentation.

Depending on the type of the historic detail it contains further properties. In case of an HistoricVariableUpdate the following properties are also provided:

Name	Value	Description
variableName	String	The name of the variable which has been updated.
variableInstanceId	String	The id of the associated variable instance.
variableType	String	The value type of the variable.
value	String/Number/Boolean/Object	The variable's value. Value differs depending on the variable's type and on the deserializeValues parameter.
valueInfo	Object	A JSON object containing additional, value-type-dependent properties. For variables of type Object, the following properties are returned: objectTypeName: A string representation of the object's type name. serializationDataFormat: The serialization format used to store the variable.
revision	number	The revision of the historic variable update.
errorMessage	String	An error message in case a Java Serialized Object could not be de-serialized.
initial	boolean	Returns true for variable updates that contains the initial values of the variables

In case of an HistoricFormField the following properties are also provided:

Name	Value	Description
fieldId	String	The id of the form field.
fieldValue	String/Number/Boolean/Object	The submitted value.

Response Codes

Code	Media type	Description
200	application/json	Request successful.
400	application/json	Returned if some of the query parameters are invalid, for example if a sortOrder parameter is supplied, but no sortBy. See the Introduction for the error response format.
