Documentation and samples on how to use likedByInformation while reading from a sharepoint list

Question

Hi ,

We are developing an upvote functionality for a single page application where we show a list of assets by reading the data from a sharepoint list
API used -
https://sitename.sharepoint.com/teams/TeamName/_api/web/lists/getbyTitle('SPListName')/items?filter=IsActive%20eq%201&$select=Id,Title,AssetDescription,ProductName,AssetType,CreatedOn,Image,LinktoAsset,Editor/Title&$expand=Editor/Id&$orderby=CreatedOn%20desc&$top=1000

We are developing an upvote functionality on this asset list and would like to give users the capability to increment the LikesCount on the Number Of Likes OOTB column on the list.

Do we have any documentation around the APIs we can use to UPDATE and GET the likedByInformation from our SP list for all the items in single call?
Also, any suggestions on API which can help us achieve this functionality for each of the items in our SPList .

Hi @Shreya Agrawal,

You could refer to the following document

https://learn.microsoft.com/en-us/openspecs/sharepoint_protocols/ms-csomspt/3af90e3a-bd2f-4d14-a99f-8ab6fe0285fa?redirectedfrom=MSDN

After doing some research, we could only update one item likedByInformation with a single rest api call. But we could get all items likedByInformation by following api

http://sharepointsite.com/sites/sitename/_api/Web/Lists/GetByTitle('List%20Name')/items?$select=Title,LikesCount,LikedBy/Title&$expand=LikedBy
