Running JSON API inside a Miva module?

[ids]

Can I run this JSON from my Miva module?

{ Edit_Product: 'shirt', CustomField_Values: { baskinv: { total_inv: 500 } } }

Would that JSON be wrapped in an:

<MvCAPTURE VARIABLE = "l.json_snippet">

<mvdo file="{ g.Module_JSON }" name="l.json" value="{ JSON_Output( l.json_snippet ) }" />

Is the first JSON sample missing something? And should there be some header output?

{
   "Store_Code": "{{Store_Code}}",
   "Miva_Request_Timestamp": "{{$timestamp}}",
   "Function": "%%SomeFunctionNameHere%%",
   {
       Edit_Product: 'shirt',
       CustomField_Values: {
          baskinv: {
          total_inv: 500
       }
   }
}

Note: wondering if the "{" around Edit_Product are needed or would result in an error?

And in this case, what would %%SomeFunctionNameHere%% actually be?

Thanks,

Scott
