How to Enable Strongly Typed Workflow Input with IntelliSense in Elsa 3.5 Designer?

[SatishKolte]

Hello Team

Question

We are using Elsa 3.5 and starting workflows programmatically using StartWorkflowAsync.

We pass workflow input like this:

var workflowInput = new Dictionary<string, object>
{
    ["InjectionInput"] = dto,
    ["InjectionId"] = dto.InjectionId,
    ["ProviderGroupId"] = dto.ProviderGroupId,
    ["IsNewRecord"] = dto.IsNewRecord,
    ["IsWorkCompRecord"] = dto.IsWorkCompRecord,
    ["OrderingAthenaDepartmentId"] = dto.OrderingAthenaDepartmentId,
    ["OrderCode"] = dto.OrderCode ?? "",
    ["IsFOIPurchase"] = dto.IsFOIPurchase,
    ["TenantId"] = dto.TenantId
};

var options = new StartWorkflowRuntimeParams
{
    Input = workflowInput,
    VersionOptions = VersionOptions.LatestAndPublished
};

await _workflowRuntime.StartWorkflowAsync(workflowDefinitionId, options);

🎯 What We Want

Inside the Elsa Designer expression editor, we want to access input properties like:

input.IsNewRecord
input.ProviderGroupId

And when typing:

input.

here is the Ui Screen for refrence

We would like IntelliSense/autocomplete to show all available properties.

❓ My Questions

What is the correct way to define strongly-typed workflow input in Elsa 3.5?

Is there a way to register a DTO as the workflow input contract?

Can we attach a JSON schema or model so the designer expression editor knows the structure?

Is IntelliSense for workflow input supported in Elsa 3.5 Designer?

📦 Environment

Elsa 3.5

.NET 9

Workflow started via StartWorkflowAsync

We would appreciate guidance on the recommended approach.

Thank you.
