Microsoft graph api always retrieves old document library name even if the library name is modified in SharePoint

Question

Hi,

I have been using Microsoft Graph api to retrieve SharePoint site's files, folders, document libraries for my application.

When i change the document library name in SharePoint, graph api always returns me the old library name in its result.

I was using the below request to retrieve all the libraries under a SharePoint site. This request was always returning old drive name even if its modified in SharePoint.

https://graph.microsoft.com/v1.0/sites/{site-id}/drives?expand=children

I also used the below request to retrieve drive by drive id. Still, the request was always returning old drive name even if its modified in SharePoint.

https://graph.microsoft.com/v1.0/sites/{site-id}/drives/{driveid}

Graph api returns the old library name always no matter how many times the library name has been modified in SharePoint.

Please help on this.

Maybe there is a delay in Postman, I used Graph Explorer and it worked fine.

This is my test process:

Hi @Nandhini. S [ INDEC 4.0 ] ,Welcome to Q&A forum!

The Microsoft Graph API caches certain data to improve performance. In this case, it is likely that the API is returning the cached data for the document library name instead of retrieving the updated name from SharePoint. To ensure that you are getting the most up-to-date information, you can use the delta query feature of the Microsoft Graph API. Delta query allows you to retrieve only the changes that have occurred since the last time you made a request. This will ensure that you are always getting the most current information for the document library name.

To use delta query, you can add the ?$deltatoken parameter to your request. The first time you make the request, the API will return a delta token in the response. You can then use this delta token in subsequent requests to retrieve only the changes that have occurred since the last request.

Here is an example of how to use delta query to retrieve the document libraries for a SharePoint site:

GET https://graph.microsoft.com/v1.0/sites/{site-id}/drives?$expand=children&$deltatoken={delta-token}

Replace {site-id} with the ID of the SharePoint site and {delta-token} with the delta token returned in the previous response.
