Sharepoint online List - REST api - unable to configure data source

Here are a few things to check. Do you have an Auth Provider created?

Authentication Provider

Create an Auth Provider (/ns/skuid/ui/datasources) and go to the Authentication Providers tab and create a new one. Match your Postman’s authentication setup as much as possible since it’s working there.

• Auth method: OAuth 2.0 / OpenID
• Provider type: Sharepoint Online
• OAuth grant type: Match your Postman’s setup. Authorization Code is likely what you’ll use
• Authorize Endpoint URL: https://{yoursite}.sharepoint.com/_layouts/15/OauthAuthorize.aspx *use your Postman url if it’s different
• Token Endpoint URL: https://accounts.accesscontrol.windows.net/{yoursite}.onmicrosoft.com/tokens/OAuth/2 *use your Postman url if it’s different
• Don’t forget to populate Client Id and Client Secret
  Save the new Auth Provider.

Data Source
Go back to the Data Source tab and create a new one with these settings

• Type: REST
• Auth Provider: the one you created
• URL endpoint: https://myspo.sharepoint.com/sites/NIntexSolutions/pocs/_api

And if all of those things checked out, in your Skuid page, how are you setting up the model? I’d create a model connecting to the datasource with a GET method with this url /Web/Lists/getbytitle(%E2%80%98PSH%20Package%20Pricing%E2%80%99)/items

It’ll immediately try to ping that URL to get metadata, so have your dev console open with the network tab open ready to troubleshoot! The errors you get in the network tab will be super helpful to track down what might be going wrong.

Hope that helps!

Thanks for the quick response, let me give this a try.

Ok, just got this working in NLX, Postman definetly made it easier. 

I used Client Credential Grant Type and pasted in my Postman values in the body and header for Resource and Authorizations. 

Little painful ;-)

Thank you for your help.
