Queries for process instances that fulfill given parameters.Parameters may be static as well as dynamic runtime properties of process instances.The size of the result set can be retrieved by using the Get Instance Count method.

Method

GET /process-instance

Parameters

Query Parameters

Name	Description
processInstanceIds	Filter by a comma-separated list of process instance ids.
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.
sortBy	Sort the results lexicographically by a given criterion. Valid values are `instanceId`, `definitionKey`, `definitionId`, `tenantId` and `businessKey`. 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.
firstResult	Pagination of results. Specifies the index of the first result to return.
maxResults	Pagination of results. Specifies the maximum number of results to return. Will return less results if there are no more results left.

Result

A JSON array of process instance objects.Each process instance object has the following properties:

Name	Value	Description
id	String	The id of the process instance.
definitionId	String	The id of the process definition that this process instance belongs to.
businessKey	String	The business key of the process instance.
caseInstanceId	String	The id of the case instance associated with the process instance.
ended	Boolean	A flag indicating whether the process instance has ended or not. Deprecated: will always be false!
suspended	Boolean	A flag indicating whether the process instance is suspended or not.
tenantId	String	The tenant id of the process instance.

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.
