Detect CostManagement export API version

[StephanQuilyx]

I'm trying to automate creating exports for subscriptions, I'm using the CostManagement REST API to create a list of exports by subscription:
GET https://management.azure.com/subscriptions/00000000-0000-0000-0000-000000000000/providers/Microsoft.CostManagement/exports?api-version=2024-08-01
(source: https://learn.microsoft.com/en-us/rest/api/cost-management/exports/list?view=rest-cost-management-2024-08-01&tabs=HTTP)

However, there's no way of knowing which API the export(s) are using, other than inspecting the Azure Portal using DevTools.
Current workaround is polling the API with every api version to populate the list.

My question; how do I know which API version I have to use to return a list of exports using the REST API?

Note; From a CSP perspective, we need to create an export for every subscription available, we do not know if subscriptions/exports change and we want to monitor this closely.

Try using the New-FinOpsCostExport PowerShell command.

But to answer your question, use 2023-07-01-preview.

@flanakin thank you for your response, 2023-07-01-preview is the correct version. Just unfortunate it's not clear in the portal/docs
