Use this method to retrieve a list of escalation entities by using a query.

Sample method invocation

GET /rest/bpm/federated/htm/v1/escalations/query/{query}[?domain={string}|systemID={string}][&selectedAttributes={string}][&interactionFilter={string}][&queryFilter={string}][&processAppName={string}][&sortAttributes={string}][&offset={integer}][&size={integer}][&admin={boolean}]

Parameters

Required Federation Parameter
NameValue TypeDescription
domain string Name of the domain containing the BPEL runtime systems that host the distributed resource (mutually exclusive with the systemID parameter).
systemID string ID of the BPEL runtime system hosting the resource (mutually exclusive with the domain parameter). If specified then this request is treated like any other request for a resource hosted by a single system, that is, the request and the response are just routed, and no pre/post-processing of parameters and results is performed by the federation layer.
Optional Parameters
NameValue TypeDescription
selectedAttributes string
Comma-separated list of attributes, in uppercase letters, which specifies the attributes that are retrieved by the query. If no selected attributes are specified, all the attributes that are defined on the query are returned and no work item information is returned.
interactionFilter string
Name of a predefined user interaction.
ValueDescription
ESCALATE
MANAGE
BROWSE_ALL
queryFilter string
A query table condition language expression that performs additional filtering on the result set. All attributes defined on the query can be referenced.
processAppName string
Name of the process application, which is used for additional filtering.
sortAttributes string
Comma-separated list of sort criteria applied to the list of returned process instance entities. Each list entry is in the form attribute [ASC|DESC] where ascending is the default.
offset integer
Specifies the number of entities to be skipped in the result set. This parameter is only allowed if the parameter systemID is also specified, and rejected in other cases.
size integer
Limits the number of entities returned. The threshold setting might not be accurate.
admin boolean
Administration authorization option specifying whether the request is performed by an administrator.
ValueDescription
true
The request is performed by an administrator. The user must have administrative rights to perform this request. If the onBehalfUser parameter is specified as well then the request is performed as if the specified user had sent the request, otherwise, the request runs as administrator.
false (default)
The request is performed by a regular user who doesn't have administrative rights.
