Hi @gbarak!
As you probably figured out, there isn't a direct way to retrieve this this information. I have tested this out and maybe you can give it a try and see whether it suits your needs. It is a little bit clunky, requiring total of 3 API calls.
Basically, query a joint object of "Subscription", "InvoiceItem" and "Account", the end result is a list of subcription IDs if these subscriptions have invoiceItem IDs associated with them, meaning invoice had been generated. You can reference the joint object "InvoiceItem" if you're interested querying other fields of the joint objects.
Call #1
Create an "Export" object via "Export ZOQL", you can see in the query, we start by querying a particular account, the object we're interested in would be "Invoice Item". Documentation to the endpoint below is here.
POST
endpoint:
https://rest.apisandbox.zuora.com/v1/action/create
Request body:
{
"objects": [
{
"Format": "csv",
"Query": "select Subscription.Id from InvoiceItem where Account.Id = '8f4552ccc597e11cec53f19b085b849b'"
}
],
"type": "Export"
}
Response:
[
{
"Success": true,
"Id": "2c92c0f963da67f80163db4e7fa2553d"
}
]
Call #2
Query for the "FileId" from Call #1 above, documentation to this endpoint is here.
POST
endpoint: https://rest.apisandbox.zuora.com/v1/action/query
Request body:
{
"queryString": "select FileId from Export where Id = '2c92c0f963da67f80163db4e7fa2553d'"
}
Response:
{
"records": [
{
"FileId": "2c92c08663da68b40163db4e80980d17",
"Id": "2c92c0f963da67f80163db4e7fa2553d"
}
],
"size": 1,
"done": true
}
Call #3
Retrieve results by providing "FileId" from Call #2, documentation to endpoint is here. If there are no IDs in the response, that means no invoice been generated. You can further query the subscripitions in the account to find out exactly which subscriptions do not have invoice generated.
GET
endpoint: https://rest.apisandbox.zuora.com/v1/files/2c92c08663da68b40163db4e80980d17
