Get Case Instances

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

Method

GET /case-instance

Parameters

Query Parameters

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 comma-separated list of tenant ids. A case instance must have one of the given tenant ids.
withoutTenantId	Only include case instances which belong to no tenant. Value may only be `true`, as `false` is the default behavior.
variables	Only include case 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.
variableNamesIgnoreCase	Match all variable names provided in `variables` case-insensitively. If set to `true` variableName and variablename are treated as equal.
variableValuesIgnoreCase	Match all variable values provided in `variables` case-insensitively. If set to `true` variableValue and variablevalue are treated as equal.
sortBy	Sort the results lexicographically by a given criterion. Valid values are `caseInstanceId`, `casedefinitionKey`, `caseDefinitionId` and `tenantId`. 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 case instance objects. Each case instance object has the following properties:

Name	Value	Description
id	String	The id of the case instance.
caseDefinitionId	String	The id of the case definition that this case instance belongs to.
businessKey	String	The business key of the case instance.
active	Boolean	A flag indicating whether the case instance is active or not.
completed	Boolean	A flag indicating whether the case instance is completed or not.
tenantId	String	The tenant id of the case 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.
