I integrated the following Outlooks Contacts API with my website this way users with a hotmail.com, outlook.com, msn.com, windows live email address can easily connect to their contacts.
https://msdn.microsoft.com/office/office365/APi/contacts-rest-operations#Getcontacts
However, I keep on receiving this error when I try to log in to my hotmail email account:
The provided value for the input parameter "redirect_uri" is not valid. The expected value is "https://login.live.com/oauth20_desktop.srf" or a URL which matches the redirect URI registered for this client application.
Does anyone know what is causing this issue?
I created my app credentials again but it still doesn't work.
Thank you!
