File browser tool with Alteryx Gallery API

[ryUser_808]

I have a workflow on alteryx gallery which has a file browser input. 
I'm calling my workflow using the gallery APIs provided in the api-docs, the User V2 api, and by following the example in the Alteryx documentation.

I have got it working when the input is an excel file with a single tab with the tab name 'Sheet1'.
The request I send looks like below (from Alteryx documentation)

{
  "questions": [
    {
      "name": "my_file_browse_tool_name",
      "value": "file_id"
    },
  ],
  "priority": "1",
  "credentialId": ""
}

In my request how can I:

• specify the tab name (when there are multiple tabs to choose from)?
• select <List of Sheet Names> option on file browser question?

When I look at the request when executing the workflow on Alteryx gallery I see the following:

I tried to modify my request so it looks like as above but I get some unspecified errors. 

Any help is appreciated.

I'm running into a similar issue. I would love to know how to specify the Sheet Name when I post a file. 

Additionally, I'm having a hard time accessing the reference ID for the file that I post. I get an ID to return upon posting it, but I'm running into file path issues when I try to execute the workflow that uses that file
