Hi @Jackson Smith ,

According to my research and testing, you can use the following REST API to remove specific user from item:

 POST https://xxxxx.sharepoint.com/sites/xxx/_api/web/lists/getbytitle('<listName>')/items(<ID>)/roleassignments/removeroleassignment(principalid=<userID>,roleDefId=1073741827)  

To get the user's principal ID, please use the following REST API:

GET https://xxxxx.sharepoint.com/sites/xxx/_api/web/siteusers/getbyemail('******@xxxx.com')   

To get the roledefID , please use the following REST API:

 GET https://xxxxx.sharepoint.com/sites/xxx/_api/web/roledefinitions/getByName('contribute')  

My test result:

1. Get the user's principal ID:
   
2. Get the roledefID:
   
3. Remove specific user from item:
   

In addition, as far as I know, unfortunately, there is currently no way to change the owner of a file using REST API.

Hope it can help you. Thanks for you understanding.

Answer 2

thanks on the answer but it doesnt work, i get the same responses as you but when i go to check the specific share link - some file -> manage access. i see the user is still get access.
also this endpoint doesnt work for external users - GET https://xxxxx.sharepoint.com/sites/xxx/_api/web/siteusers/getbyemail('xxx[@](/users/na/?userId=189d14d4-bffd-0003-0000-000000000000).com') get User cannot be found.

maybe this ep will help to change the invitees - https://learn.microsoft.com/en-us/openspecs/sharepoint_protocols/ms-csomspt/4cb29f91-2c41-44d4-892c-80ee0ea9a0f3
but i need help how to use it because its not clear from the docs.

Basically i want to remove invitation under link element -> POST _api/web/lists()/items()/GetSharingInformation

Thanks alot!
