Sharepoint REST API calls returning 404 not found

Question

We are trying to access SharePoint REST APIs, each call to them returns with 404 NOT Found error. We tried to check https://sitename/_api/contextInfo, there was again 404 error in response.

We are trying to access this API from an IOS app. Tried the same from POSTMAN to confirm the same.

Kindly advice.

Answer 1

The correct one is https://sitename/_api/web. If you type this URL in a browser like Chrome, it should display the current site information in XML.

Also check your protocol, it might be https instead of http.

If you still get the error than you need to download the SP 2013 Client Components SDK & brought up PowerShell V3

Use below mentioned code in PowerShell V3

# Invoke-RestSPO -Url "https://XXXXXXXX.sharepoint.com/_api/web"

Above code came from below mentioned code
