I am getting this error when trying to connect to sharepoint via a reader

Hi Edward,

I think you are you using a template for your Microsoft SharePoint Online web connection that needs some modification. Two options that might work. You can either modify this one for your organization or use the Safe one which seems to work for us.

In either case go to Tools - FME Options - Settings - Web Connections - Manage Services.

1. The default Microsoft SharePoint Online (Template) has a place holder in the Authorization URL that looks like this:

https://" alt="https://login.microsoftonline.com/common/oauth2/v2.0/authorize?scope=https://" target="_blank">https://login.microsoftonline.com/common/oauth2/v2.0/authorize?scope=https://[TENANT].sharepoint.com/.default offline_access&response_type=code&prompt=consent

so at the very least you have to replace tenant with yours but you would also need a client id and Client Secret from the Azure Enterprise Apps settings.

2. Alternatively you could create your web connection from the other template in there called Microsoft SharePoint Online (safe.microsoft-sharepoint)

This second option seems to work for us.
