HI @Shane Paulsen , The error message indicates that the client secret provided for the app registration is invalid. The client secret is a secret key that is used to authenticate the app registration with the OneDrive API. To fix this error, you can try the following steps:
- Double-check that the client secret you entered in the WP File Download plugin matches the client secret in the Azure portal for your app registration. Make sure there are no extra spaces or characters in the client secret.
- Ensure that the client secret has not expired. In the Azure portal, go to the app registration's "Certificates & secrets" page and check the expiration date of the client secret. If it has expired, generate a new one and update it in the WP File Download plugin.
- Check the permissions of the app registration in the Azure portal. Make sure that the app registration has the necessary permissions to access the OneDrive API. You can do this by going to the "API permissions" page of the app registration and verifying that the necessary permissions are granted.
- Check that the app registration is properly configured to use the correct OAuth version. The error message indicates that the API is using version 2.0, so make sure that the app registration is also configured to use OAuth 2.0. Regards, Divya
