Get Process Instance Count (POST)
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. |
| withIncidents | Only include process instances which have an 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. The date must have the format yyyy-MM-dd'T'HH:mm:ss, e.g., 2013-01-23T14:42:45. |
| startedAfter | Restrict to instances that were started after the given date. The date must have the format yyyy-MM-dd'T'HH:mm:ss, e.g., 2013-01-23T14:42:45. |

| finishedAfter | Restrict to instances that were finished after the given date. The date must have the format yyyy-MM-dd'T'HH:mm:ss, e.g., 2013-01-23T14:42:45. |
| 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. |
Result
A JSON object that contains the count as the only property.
| Name | Value | Description |
|---|---|---|
| count | Number | The number of matching historic process instances. |
Response Codes
| Code | Media type | Description |
|---|---|---|
| 200 | application/json | Request successful. |
