I need some help with the Graph Explorer. I have already used the Get Command https://graph.microsoft.com/v1.0/contacts to get all global contacts. But now I would like to write all of these contacts into a private user profile (i.e. into his private contact list). For this I used the POST command https://graph.microsoft.com/v1.0/me/contacts. (Yes I know me is my own, I use this first for testing. Then I submitted all the values that were output at https://graph.microsoft.com/v1.0/contacts to the POST request. Unfortunately I always get the following error message
what am i doing wrong?
