Get request details from vRO or vRA API

Hi,

I'm using vRA and vRO 7.3.0 and I want to get the detail of a catalog item request from vRO. I want to have access to request information, like in vRA. For example, for a machine blueprint request, vRA shows us CPU, components description, custom properties, etc. All user inputs are available:

I try to get the same information using vRO or the vRA API but without success. I can get some request common information, but not the detail of the input form like above.

I'm using this API call to get the request : https://{{va-fqdn}}/catalog-service/api/consumer/requests?$filter=requestedFor eq '{{username@domain}}'

I think that data I want should be in the "requestData" section, it's why I understand here: https://communities.vmware.com/thread/535074#2599862. But all that I have is something like this:

"requestData": {
"entries": [
{
"key": "provider-_leaseDays",
"value": null
},
{
"key": "provider-vSphere__vCenter__Machine_1",
"value": {
"type": "complex",
"componentTypeId": null,
"componentId": null,
"classId": null,
"typeFilter": null,
"values": {
"entries": []
}
}
},
{
"key": "provider-vSphere__vCenter__Machine_2",
"value": {
"type": "complex",
"componentTypeId": null,
"componentId": null,
"classId": null,
"typeFilter": null,
"values": {
"entries": []
}
}
}
]
}

Not very useful. When I get the request with vRO (either with vCACCAFEEntitiesFinder or vCACCAFECatalogConsumerRequestService) I have the same result.

I know that data I need are somewhere (I can see it in vRA), but I have no idea where to look for it.

Thanks for your help!
