| 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 comma-separated list of tenant ids. A process instance must have one of the given tenant ids. |
| 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 comma-separated 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 | Only include process instances that have variables with certain values.
Variable filtering expressions are comma-separated and are structured as follows: A valid parameter value has the form key_operator_value.
key is the variable name, operator is the comparison operator to be used and value the variable value.Note: Values are always treated as String objects on server side.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.key and value may not contain underscore or comma characters.
