[Azure REST API] call rate and data retention

Question

[Azure REST API] call rate and data retention

Han Shih 施學翰 146

I try to create dashboard based on Azure REST API
And my data comes from Azure APIM

Here are my questions:

I wonder if there exists an API call rate limit of these APIs?
(e.g. 3600 requests/hour)
How long the data behind these APIs will be kept?
(e.g. I want to request the data about a year ago, is it possible?)

Thanks

Hi @Han Shih 施學翰

As per the section Async operations, throttling, and paging it is the same limit as mentioned in Subscription and tenant limits. The endpoint that are hit is management.azure.com

Resource Manager applies a limit on the number of read and write requests per hour to prevent an application from sending too many requests. If your application exceeds those limits, requests are throttled. The response header includes the number of remaining requests for your scope. For more information, see Throttling Resource Manager requests.

Can you elaborate more what do you mean by "How long the data behind these APIs will be kept?" Did you mean you can calling the report API for APIM and want to check what is the retention for the data that is returned from this API. If this is the case then this data is persisted in individual API Management instances for Reports API and the data is currently retained indefinitely till you are not deleting the APIM instance.

Hello @MayankBargali-MSFT

Thanks for your reply, below is my understanding based on the information you provided.
Correct me if I am wrong.

According to Subscription and tenant limits , APIM report API should be "subscription-level" operation.

In Remaining requests , it shows that I can get the number of API calls left for the current hour. However, I can not find it in the response header. (Maybe I should add something in request header in order to get these information?)

The data behind APIM REST API, exists forever. I can send a request to acquire data even 10 years ago (if exist).

@Han Shih 施學翰 The document which you have shared initial is for Azure Management REST API where as your screenshot stats that you are using the APIM Direct Management API. If you are using the direct Management API then it will bypass the ARM's limitation that I have shared previously. You can refer to API Management REST document. Therefore you will not see the remaining request as you mentioned in your second point since there is no limit as such for APIM Direct Management API.
For your third point the APIM reports data exist as long you are not deleting the instance.

Hope the above clears things up. Feel free to get back to me if you have any queries or concerns.
