Hi everyone,
I have an API call that will start a mingle workflow via the process API. When I do the test in API Gateway it works as expected:

I have set a logical ID and used JSON for the body

{
"workflowName": "VOL_PODeviation_Approval",
"instanceName": "DEV",
"inputVariables": [
{
"name": "Configuration",
"dataType": "STRING",
"value": "XYG"
},
{
"name": "LogicalID",
"dataType": "STRING",
"value": "XYG"
},
{
"name": "POLine",
"dataType": "STRING",
"value": "1"
},
{
"name": "PONum",
"dataType": "STRING",
"value": "3PO123"
}]
}
I would like to call this via Mongoose ION API. However, I cannot figure out how to convert the logical ID and JSON into a format that is understood:

I know I am doing something really wrong here - but does anyone have experience/success in calling API through ION API Invoke?
Thanks
Ryan
