Get SharePoint Document Library Name from File Unique ID

Have you recieved a use case where you need to know the Document Library Name from the Unique Id of the File. Let us assume you have a URL with unique File id something similar to this,

` https://contoso.sharepoint.com/:w:/r/sites/contososite/_layouts/15/Doc.aspx?sourcedoc=%7BD0E8F75B-DCD7-478E-9CAA-41944F21D722%7D&file=MySharingCentral.docx&action=default&mobileredirect=true `

You know that the File Unique ID is D0E8F75B-DCD7-478E-9CAA-41944F21D722 How do we get to know the Document Library Name and if needed Item id from there? There is a REST API Method GetFileById via which you will be able to get the information about the file. But by default, you will just get the information about the file without library information. There comes the life safer expand parameter, ListItemAllFields/ParentList. With the expansion for ParentList attribute, you will get the information about the List / Library where the file belongs to. How cool is that? Now the whole API call may look something similar to this,

https://contoso.sharepoint.com/sites/contososite/_api/web/GetFileById('d0e8f75b-dcd7-478e-9caa-41944f21d722')/?$expand=ListItemAllFields/ParentList

and Bingo, you will get the result like below.

    {
        "ListItemAllFields": {
            "ParentList": {
                "AllowContentTypes": true,
                "BaseTemplate": 101,

                "LastItemModifiedDate": "2020-11-13T14:42:14Z",
                "LastItemUserModifiedDate": "2020-11-04T15:18:26Z",
                "ListExperienceOptions": 0,
                "ListItemEntityTypeFullName": "SP.Data.Shared_x0020_DocumentsItem",
                "MajorVersionLimit": 500,
                "MajorWithMinorVersionsLimit": 0,
                "MultipleDataList": false,
                "NoCrawl": false,
                "ParentWebPath": {
                    "DecodedUrl": "/sites/contososite"
                },
                "ParentWebUrl": "/sites/contososite",
                "ParserDisabled": false,
                "ServerTemplateCanCreateFolders": true,
                "TemplateFeatureId": "00bfea71-e717-4e80-aa17-d0c71b360101",
                "Title": "Documents"
            },
    }

And you can can see that there is a property called Title which is basically the name of your document library.
