Call External System URL from Siebel

Hello Experts,

We are using Siebel CRM version 20.12.

In our application, we open an external web system from Browser Script using:

window.open("URL_VALUE");

Previously, the external system allowed authentication by passing username and password in the URL, for example:

https://externalsystem.domain.com/?username=AMEEN&password=Abcd

Our script was dynamically building and opening this URL.

Recently, the external system stopped supporting username/password in the URL for security reasons. Because of this, our current integration is no longer working.

What is the recommended or supported approach in Siebel 20.12 to handle this scenario where:

• A user needs to be redirected/open an external web application from Siebel UI
