Hi,

We have the following use case: We are a service provider with customers using TOPdesk as a service management tool. They use the service portal provided by TOPdesk and log into TOPdesk. We want to establish a connection from the TOPdesk portal to the ServiceNow CSM portal.

 

Our question is: How can we facilitate a Single Sign-On (SSO) experience for customers using TOPdesk, so they can seamlessly enter the CSM portal without a second login? The user information of the customer is already present in ServiceNow. We use Azure Entra AD.

Hi @Community Alums,

 

Thank you for your answer. However, this solution assumes that users log in to CSM using a ServiceNow contact directly. That's why the script is able to get the logged-in user's sys_id with getUserID().

 

In our case, the user opens our CSM portal from their TOPdesk portal where they are logged in on their own domain, for instance, their Azure AD. Thats why I think an SSO solution is needed.
