How to control the Response from Sharepoint API "GET /sites/{siteId}/drives".

Question

I am using the API endpoint "GET /sites/{siteId}/drives" to retrieve a list of libraries.

I use the query, "top", but the response does not return the expected number of items.

For example, if there are 8 document libraries and I specify $top=10, the response only returns 5 items.

I have three questions:

1. Why does the response from "/sites/{siteId}/drives" not match the specified "top" value?

2. Are there any ways to prevent the issue described in question 1?

3. Is there an upper limit for the "top" value??

Thank you for your assistance.

Answer 1

Hi

The discrepancy arises because the /sites/{siteId}/drives endpoint does not return system libraries, even though they exist. The Microsoft Graph API filters out libraries such as:

• Site Assets
• Other system-generated libraries

Even if $top is set higher than the number of user-created libraries, the system will not include system drives in the response unless explicitly.

You can try to include system to include system libraries: /sites/{siteId}/drives?$select=id,name,system&top=5

Then the accurate number of items is returned.
