Frequently Asked Questions

Why can't I get SharePoint API support in the standard Microsoft Community?

The standard Microsoft Community is designed for general end-user software issues. SharePoint REST API, app-only permissions, and tenant-wide configurations require specialized developer knowledge, which is exclusively handled in the Microsoft Q&A developer forums.

What information should I include when asking for SharePoint API help?

To get an accurate solution from developer support, you must include your requested permission XML, the specific authentication method you are using, your tenant type, and the full text of any API error messages you receive.

How do I grant tenant-wide permissions via the SharePoint REST API?

Tenant-wide permissions generally require administrative consent and must be configured via the SharePoint admin center or the specific appinv.aspx endpoint, using a properly formatted permission XML request.

Are app-only permissions supported in all SharePoint environments?

App-only permissions are supported in SharePoint Online, but specific configurations might differ depending on your tenant's security policies, such as whether modern authentication is strictly enforced or legacy protocols are disabled.
