Resolve a Users PrincipalId to share file or Folder REST API

Question

Is there a way to get a users PrincipalId based on their email address. I'm looking to share/apply permissions to files and folders in a users OneDrive to Business drive using the REST API.

Answer 1

SP.UserCollection object contains the SP.UserCollection.getByEmail Method to get the user with the specified email address. The following example demonstrates how to get SP.User Id property:

/_api/web/SiteUsers/getByEmail('[email protected]')/Id

Alternatively you could utilize the following query:

/_api/web/SiteUsers?$select=id&$filter=Email eq '[email protected]'
