When I attempt to go to
'https:// -site- /_layouts/15/AppRegNew.aspx' in order to enter OAuth info for my REST based service, I get the message
"Sorry, you don't have access to this page."
where -site- is:
sub.company.com/marketing/more/another/ which is the valid URL for the SharePoint site, and I can access this.
The SharePoint Admin says I have full rights to the AppRegNew page. The Admin also gets the same message when she tries to go there. Is there something that needs to be installed to allow this?
I can use REST endpoints to view xml output when I enter it in a browser. However, when I write the code to call the REST service, I get the error back "Access Denied". It is my understanding I need to get an OAuth token via the process documented here: http://spshell.blogspot.com/2015/03/sharepoint-online-o365-oauth.html.
Which is what I am trying to do, but I can't even get to the registration of a new service. Maybe I am going about this the wrong way, if so, could you kindly point me in the correct direction?
