We had our client create a new sandbox for us to test imports without workflows (imports work on the original sandbox.) I'm authenticated into D365 using an Active Directory app with a certificate sent from the C# code and my thought process was to just replace all instances of the old base url of {sandbox-name}.api.crm.dynamics
or {sandbox-name}.crm.dynamics
with {new-sandbox-name}.api.crm.dynamics
and {new-sandbox-name}.crm.dynamics
. I'm getting a 401 error now when trying to import data.
I can't find in the Active Directory app where the certificate that we created is tied only to that original sandbox url, so is there something obvious I'm missing?
In your new Sandbox D365 CRM, go and create the Application user in system user table with the right security role/privilege. Then it should work.
