## Constructors

### <a id="Tracon_WorkflowResumeRequest__ctor"></a> WorkflowResumeRequest\(\)

```csharp
public WorkflowResumeRequest()
```

## Properties

### <a id="Tracon_WorkflowResumeRequest_CheckpointId"></a> CheckpointId

The identifier of the checkpoint to resume from. If left empty, that
run's *most recent* checkpoint is used.

```csharp
public string? CheckpointId { get; init; }
```

#### Property Value

 [string](https://learn.microsoft.com/dotnet/api/system.string)?

### <a id="Tracon_WorkflowResumeRequest_DefinitionVersion"></a> DefinitionVersion

The version of the workflow's stored definition to resume with.
[null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) (the default) resumes with the version the source run
recorded, so an edit made while the run waited does not change what resumes.

```csharp
public int? DefinitionVersion { get; init; }
```

#### Property Value

 [int](https://learn.microsoft.com/dotnet/api/system.int32)?

#### Remarks

A source run that recorded no version (it predates version recording, or the
workflow is defined in code) resumes with the current definition. A version the
workflow does not have is refused with a [TraconException](/api/tracon.traconexception/) before any run row is
opened; the run never falls back to the current definition.

Naming a version whose graph differs from the one the checkpoint was written
with fails the run with "the graph's structure differs": the checkpoint belongs
to the graph it was written from. That is how an operator carries a run over a
fix, when the fix did not change the structure.

### <a id="Tracon_WorkflowResumeRequest_NewRunId"></a> NewRunId

The new run's identifier. If given, the record is opened with this identifier.

```csharp
public Guid? NewRunId { get; init; }
```

#### Property Value

 [Guid](https://learn.microsoft.com/dotnet/api/system.guid)?

### <a id="Tracon_WorkflowResumeRequest_RunId"></a> RunId

The identifier of the run to resume.

```csharp
public required Guid RunId { get; init; }
```

#### Property Value

 [Guid](https://learn.microsoft.com/dotnet/api/system.guid)
