When calling the rest API to retrieve the variables: runtime/process-instances/{processInstanceId}/variables

They are all returned with the corresponding values.

Same when calling the tasks variables API: runtime/tasks/{taskId}/variables?scope={scope}

<javascript>
[
{
    "name": "existsInSystem",
    "type": "boolean",
    "value": true,
    "scope": "global"
},
{
    "name": "paymentDocument",
    "value": null,
    "scope": "global"
},
{
    "name": "backendSystem",
    "type": "string",
    "value": "EVEREST",
    "scope": "global"
},
{
    "name": "initiator",
    "type": "string",
    "value": "1",
    "scope": "global"
},
{
    "name": "performer",
    "type": "string",
    "value": "Michael Jackson",
    "scope": "global"
},
{
    "name": "paymentReference",
    "type": "string",
    "value": "asdf",
    "scope": "global"
},
{
    "name": "limit",
    "type": "string",
    "value": "3000",
    "scope": "global"
},
{
    "name": "account",
    "type": "string",
    "value": "My Account",
    "scope": "global"
}

So from those list, which one is one from the start form that works?
But you are correct, both should work just as-is, irregardless where they came from.

Thanks for coming back to me.

From the list paymentReference and paymentDocument are the ones filled in the start form. I just ignored paymentDocument field because I didn't find a OOTB way to show a document in the Beta version.
