Get Instances (POST)

Queries for process instances that fulfill given parameters through a JSON object. This method is slightly more powerful than the Get Instances method because it allows filtering by multiple process variables of types String, Number or Boolean.

Method

POST /process-instance

Parameters

Query Parameters

Name	Description
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.

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 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.

sorting

A JSON array of criteria to sort the result by. Each element of the array is a JSON object that specifies one ordering. The position in the array identifies the rank of an ordering, i.e., whether it is primary, secondary, etc. The ordering objects have the following properties:

sortBy	Mandatory. Sort the results lexicographically by a given criterion. Valid values are `instanceId`, `definitionKey`, `definitionId`, `tenantId` and `businessKey`.
sortOrder	Mandatory. Sort the results in a given order. Values may be `asc` for ascending order or `desc` for descending order.

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.
