Queries for the number of historic process instances that fulfill the given parameters.This method takes the same message body as the Get Process Instances (POST) method and therefore it is slightly more powerful than the Get Process Instance Count method.

Method

POST /history/process-instance/count

Parameters

Request Body

A JSON object with the following properties:

Name	Description
processInstanceId	Filter by process instance id.
processInstanceIds	Filter by process instance ids. Must be a comma-separated list of process instance ids.
processInstanceBusinessKey	Filter by process instance business key.
processInstanceBusinessKeyLike	Filter by process instance business key that the parameter is a substring of.
superProcessInstanceId	Restrict query to all process instances that are sub process instances of the given process instance. Takes a process instance id.
subProcessInstanceId	Restrict query to one process instance that has a sub process instance with the given id.
superCaseInstanceId	Restrict query to all process instances that are sub process instances of the given case instance. Takes a case instance id.
subCaseInstanceId	Restrict query to one process instance that has a sub case instance with the given id.
caseInstanceId	Restrict query to all process instances that are sub process instances of the given case instance. Takes a case instance id.
processDefinitionId	Filter by the process definition the instances run on.
processDefinitionKey	Filter by the key of the process definition the instances run on.
processDefinitionKeyNotIn	Exclude instances that belong to a set of process definitions. Must be a comma-separated list of process definition keys.
processDefinitionName	Filter by the name of the process definition the instances run on.
processDefinitionNameLike	Filter by process definition names that the parameter is a substring of.
finished	Only include finished process instances. Value may only be `true`, as `false` is the default behavior.
unfinished	Only include unfinished process instances. Value may only be `true`, as `false` is the default behavior.
incidentType	Filter by the incident type. See the User Guide for a list of incident types.
withIncidents	Only include process instances which have an incident. Value may only be `true`, as `false` is the default behavior.
withRootIncidents	Only include process instances which have a root incident. Value may only be `true`, as `false` is the default behavior.
incidentStatus	Only include process instances which have an incident in status either `open` or `resolved`. To get all process instances, use the query parameter `withIncidents`.
incidentMessage	Filter by the incident message. Exact match.
incidentMessageLike	Filter by the incident message that the parameter is a substring of.
startedBy	Only include process instances that were started by the given user.
startedBefore	Restrict to instances that were started before the given date. By default*, the date must have the format `yyyy-MM-dd'T'HHss.SSSZ`, e.g., `2013-01-23T14:42:45.000+0200`.
startedAfter	Restrict to instances that were started after the given date. By default*, the date must have the format `yyyy-MM-dd'T'HHss.SSSZ`, e.g., `2013-01-23T14:42:45.000+0200`.
finishedBefore	Restrict to instances that were finished before the given date. By default*, the date must have the format `yyyy-MM-dd'T'HHss.SSSZ`, e.g., `2013-01-23T14:42:45.000+0200`.

tenantIdIn	Filter by a list of tenant ids. A process instance must have one of the given tenant ids. Must be a JSON array of Strings.
variables	A JSON array to only include process instances that have/had variables with certain values. The array consists of objects with the three properties `name`, `operator` and `value`. `name (String)` is the variable name, `operator (String)` is the comparison operator to be used and `value` the variable value. `value` may be `String`, `Number` or `Boolean`. 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`.
executedActivityBefore	Restrict to instances that executed an activity before the given date (inclusive). By default*, the date must have the format `yyyy-MM-dd'T'HHss.SSSZ`, e.g., `2013-01-23T14:42:45.000+0200`.
executedActivityAfter	Restrict to instances that executed an activity after the given date (inclusive). By default*, the date must have the format `yyyy-MM-dd'T'HHss.SSSZ`, e.g., `2013-01-23T14:42:45.000+0200`.
executedActivityIdIn	Restrict to instances that executed an activity with one of given ids.
activeActivityIdIn	Restrict to instances that have an active activity with one of given ids.

active	Restrict to instances that are active
suspended	Restrict to instances that are suspended
completed	Restrict to instances that are completed
externallyTerminated	Restrict to instances that are externally terminated
internallyTerminated	Restrict to instances that are internally terminated
