Get Case Instance Count (POST)
Queries for the number of case instances that fulfill the given parameters. This method takes the same message body as the Get Case Instance (POST) method and therefore it is slightly more powerful than the Get Case Instance Count method.
Method
POST /case-instance/count
Parameters
Request Body
A JSON object with the following properties:
| Name | Description |
|---|---|
| caseInstanceId | Filter by a case instance id. |
| businessKey | Filter by case instance business key. |
| caseDefinitionId | Filter by the case definition the case instances run on. |
| caseDefinitionKey | Filter by the key of the case definition the case instances run on. |
| deploymentId | Filter by the deployment the id belongs to. |
| superProcessInstance | Restrict query to all case instances that are sub case instances of the given process instance. Takes a process instance id. |
| subProcessInstance | Restrict query to all case instances that have the given process instance as a sub process instance. Takes a process instance id. |
| superCaseInstance | Restrict query to all case instances that are sub case instances of the given case instance. Takes a case instance id. |
| subCaseInstance | Restrict query to all case instances that have the given case instance as a sub case instance. Takes a case instance id. |
| active | Only include active case instances. Value may only be true, as false is the default behavior. |
| completed | Only include completed case instances. Value may only be true, as false is the default behavior. |
| tenantIdIn | Filter by a list of tenant ids. A case instance must have one of the given tenant ids. Must be a JSON array of Strings. |

| sortBy | Sort the results lexicographically by a given criterion. Valid values are
caseInstanceId, caseDefinitionKey and caseDefinitionId.
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. |
Result
A JSON object that contains the count as the only property.
