Get call record api https://learn.microsoft.com/en-us/graph/api/callrecords-callrecord-get?view=graph-rest-1.0&tabs=http has rate limit of 5000 requests per 10 seconds. It is per app for all tenants.
I wanted to understand "per app for all tenants". Suppose there are 2 apps for same tenant then each app has limit of 5000 req per 10 seconds ?
Adding answer from comment section for more visibilty.
For "per app for all tenants", so each app will have their own App registration, App service etc. So for 2 apps, there will be different resources and for each app will have their own rate limit of 5000 requests per 10 seconds.
