```csharp
public enum RequestElements
```

## Fields

`notcorrect = 0` 

Indicates that a request element name was not recognized.

`operation = 1` 

Specifies an operation name from [Operations](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/) or the name of a registered [IDesignerAction](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/IDesignerAction/) extension operation.

`schemecode = 2` 

Specifies the process scheme code used to select or name a process scheme.

`schemeid = 3` 

Specifies the process scheme identifier used to select a process scheme.

`processid = 4` 

Specifies the process identifier targeted by an operation.

`data = 5` 

Contains the serialized request payload whose structure depends on the selected [Operations](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/) value.

`category = 6` 

Specifies the [SuggestionCategory](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/SuggestionCategory/) used by [Operations.getautocompletesuggestions](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/).

`type = 7` 

Specifies the [CodeActionType](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/CodeActionType/) used by [Operations.getcodeactionparameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/).

`value = 8` 

Specifies the rule, action, or condition name used as context by [Operations.getautocompletesuggestions](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/).

`name = 9` 

Specifies an action, condition, or rule name for [Operations.getcodeactionparameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/) or a user name filter for [Operations.getuseridentities](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/).

`newschemecode = 10` 

Specifies the code assigned when [Operations.load](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/) creates a new process scheme.

`expression = 11` 

Contains the expression whose compilation is tested by [Operations.perform](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/).

`pagingindex = 12` 

Specifies the [Paging.PageIndex](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Persistence/Paging/) for paged results. A value of -1 disables paging for [Operations.getuseridentities](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/).

`pagingsize = 13` 

Specifies the [Paging.PageSize](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Persistence/Paging/) for paged results.

`processidforrequest = 14` 

Specifies the process identifier whose history is requested by [Operations.getprocesshistorypage](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/).

`expressiontype = 15` 

Specifies the expression result type for [Operations.perform](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/Operations/). The value `object` uses [object](https://learn.microsoft.com/dotnet/api/system.object); any other value uses [bool](https://learn.microsoft.com/dotnet/api/system.boolean).

`TenantId = 16` 

Specifies the tenant identifier that scopes process scheme operations.
