I am having 2 Single Line Of Text column for FirstName and LastName.
Now I want to get SharePoint Online users with given FirstName and LastName.
Any suggestion welcomed.
Here is source
What I did is, I used following URL to make my REST Call
SiteUrl/_vti_bin/ListData.svc/UserInformationList?$filter = ((FirstName eq 'MyFirstName') and (LastName eq 'MyLastName'))
It returned me all the information I need.
