I am trying to add a "Customer Community Plus User" profile user with the Salesforce .Net api. I have not done any configuration changes to this profile.
//Try to add user with a contact
Salesforce.Common.Models.SuccessResponse responseMsg = await client.CreateAsync("User", user);
I manage to add other profile types such as Chatter Free users via the api. But here I am getting "No access to portal" error. What is this issue? Do I need to do any configuration changes in the Salesforce portal for this profile?
