I'm not a Sharepoint developer. I'm attempting to build an API from a php application to talk to the file storage within a Sharepoint site. From what I can The RESTful API makes the most sense to use from what we can see.
I've arranged for Sharepoint/Office365 installation, and have set up a Sharepoint site. I've uploaded a file. Now i'd like to expose this using the restful API.
My understanding is that to do this, the an Azure Application must be created and this Application then offers access to the site.
I've been following the tutorial below: SharePoint Online REST API Authentication In POSTMAN
However, there is an issue that I cannot get past. It seems a permissions issue. SO:
Following the aforementioned tutorial:
1) I have created a registered app in Azure
2) Within required permissions, I have attempted to add API access
SharePoint Online is not an option, and most Sharepoint Options are greyed out.
SharePoint Online CLient, which is present is the desired choice. This is greyed out.
The only available SharePoint option is
Sharepoint Online Client Extensibility Web Application Principle.
Given that the intended option is missing, wow do I find/enable the correct option?
I am the site owner, and only email account associated with the whole sharepoint/office365 installation.
