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.
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.
sortBy Sort the results lexicographically by a given criterion. Valid values are caseInstanceId, casedefinitionKey and caseDefinitionId. 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.
