How to set up quota by subscription in Azure API portal ?
When adding this policy to the API,
<quota calls="10000" bandwidth="40000" renewal-period="3600" />
The below warning would be shown.
Error in element 'quota' on line 18, column 9: Policy is not allowed in the specified scope
If i set up quota limitation by key, then its fine. However, the email notification only works for the quota limit set up by subscription
<quota-by-key calls="10" bandwidth="1000" renewal-period="700000" counter-key="@(context.Request.IpAddress)" />
