Hi, Tim.

There are multiple types of applications that you can use where you can implement REST API calls.
You can use the Assembly application for example.

1- Create your Class Library in Visual Studio where you’ll be able to launch your REST API call and make sure the object returned represents your JSON string.
2- Build the application and copy all the assembly files (.DLL) to ~\wfgen\bin
3- Create the application by indicating the name of your assembly file (ASSEMBLY_NAME.DLL) and the method used that returns the JSON string.

For more information regarding applications, kindly consult the following documentation:

Hi, Tim

Since the returned value is a JSON string, you will need to retrieve the value in the .NET code-behind editor and bind the dropdown on page load.

One way to do it is to create a hidden TEXTBOX field and map the RETURN_VALUE data as a VALUE IN to that textbox.

Then in the .NET code behind editor, right after the page load, you can retrieve the JSON string and perform a databind to the desired dropdown list.

protected void Page_Load(object sender, EventArgs e)
	{
	    base.Page_Load(sender, e);
            // retrieve JSON string from hidden textbox and bind dropdown list
	}

Best Regards,
Eddy.

Hi Tim,

In the Form Designer,

1- Click on Mapping
2- Click on the action where you’re supposed to retrieve the returned value
3- Click on the VALUE IN of the textbox and select the data RETURN_VALUE.

Hi Eddy

I already map the RETURN_VALUE to the hidden TEXTBOX by add a new action with my application type and set the VALUE_IN to the TEXTBOX, but there was no value show in the field
Is it possible to run a small test for the specific application in workflowgen?

.dll source code

public static string getMember()
{
var url = “https://jsonplaceholder.typicode.com/posts”;
var client = new RestClient(url);
IRestResponse response = client.Execute(new RestRequest());
Console.WriteLine(response.Content);
return response.Content;
}
