Azure Billing API returns nothing

Question

I want to read current charges of my Azure Subscription programmatically. I currently use the sources from Microsofts GitHub samples .

I added an application to my AAD and gave it all permissions on 2 areas:

I configured my subscription id and the client id of the app. When I try to get the charges with the following url:

https://management.azure.com/subscriptions/{Subscription-ID}/providers/Microsoft.Commerce/UsageAggregates?api-version=2015-06-01-preview&reportedstartTime=2015-07-01+00%3a00%3a00Z&reportedEndTime=2015-08-31+00%3a00%3a00Z

This link queries 2 months but returns nothing. My Azure portal gives me current charges.

Answer 1

Aah...I should have seen it sooner. I just realized that you're fetching data for last year. Billing and Usage data is only kept for last 3 months (90 days to be precise) and because of this you're not getting any data back.
