Rate Limit on power bi metadata scanning APIs

[xhan]

We are using power bi metadata scanning APIs listed here https://learn.microsoft.com/en-us/power-bi/enterprise/service-admin-metadata-scanning.

1. The rate limit mentioned for `PostWorkspaceInfo` https://learn.microsoft.com/en-us/rest/api/power-bi/admin/workspace-info-post-workspace-info is 500 per hour and 16 simultaneous. We usually get error 429 when we made about 490+ calls (definitely not hitting 500). Why is that?

2. The rate limit mentioned for `GetScanResult` https://learn.microsoft.com/en-us/rest/api/power-bi/admin/workspace-info-get-scan-status is 500 per hour. This is usually called after `PostWorkspaceInfo`. We'd get error code 429 after 300 calls.

How's actually the rate limits working here?

Hi @xhan,

These limitations should covered on all API usages, they not only evaluated on the current one.
In addition, power bi usage also invoke some backend API, they may also be include into the total amount.
I suppose the above may be the reason it mentions usage has exceeded the limit when your requests did not real meet to the definition amounts.
