I am trying to implement a service for portal and system users using the documentation in https://academy.creatio.com/docs/8-0/developer/application_components/portal/self_service_portal/overview
The service has the following code:
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class Service1 : BaseService
For system users the service works fine but when I try to access the service from postman authenticated as a portal user I get the following message : "IS 10.0 Detailed Error - 403.0 - Access to non-SSP API is denied for portal users" with 403 status code. Is something that I am missing in the service implementation or in web.config?
