Get Instance Count (POST)
Queries for the number of process instances that fulfill the given parameters. This method takes the same message body as the Get Instances (POST) method and therefore it is slightly more powerful than the Get Instance Count method.
Method
POST /process-instance/count
Parameters
Request Body
A JSON object with the following properties:
| Name | Description |
|---|---|
| processInstanceIds | Filter by a list of process instance ids. Must be a JSON array of Strings. |
| businessKey | Filter by process instance business key. |
| businessKeyLike | Filter by process instance business key that the parameter is a substring of. |
| caseInstanceId | Filter by 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. |
| deploymentId | Filter by the deployment the id belongs to. |
| superProcessInstance | Restrict query to all process instances that are sub process instances of the given process instance. Takes a process instance id. |
| subProcessInstance | Restrict query to all process instances that have the given process instance as a sub process instance. Takes a process instance id. |
| superCaseInstance | Restrict query to all process instances that are sub process instances of the given case instance. Takes a case instance id. |
| subCaseInstance | Restrict query to all process instances that have the given case instance as a sub case instance. Takes a case instance id. |
| active | Only include active process instances. Value may only be true, as false is the default behavior. |
| suspended | Only include suspended process instances. Value may only be true, as false is the default behavior. |
| incidentId | Filter by the incident id. |
| incidentType | Filter by the incident type. See the User Guide for a list of incident types. |
| incidentMessage | Filter by the incident message. Exact match. |
| incidentMessageLike | Filter by the incident message that the parameter is a substring of. |
| 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. |
| withoutTenantId | Only include process instances which belong to no tenant. Value may only be true, as false is the default behavior. |
| activityIdIn | Filter by a list of activity ids. A process instance must currently wait in a leaf activity with one of the given activity ids. |
| rootProcessInstances | Restrict the query to all process instances that are top level process instances. |
| variables | A JSON array to only include process instances that have variables with certain values. The array consists of objects with the three properties key, operator and value.
key (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 process instances. |
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, or if an invalid operator for variable comparison is used. See the Introduction for the error response format. |
