Can I integrate a repository with dynamic URLs?

No, you can not integrate a repository that has dynamic URL.

A dynamic URL has a URL path that is divided into two parts. One part of the URL path is dependent on user-defined variables that keep changing to display specific information depending on user inputs. The other part of the URL path is independent of user inputs and remains constant throughout the application.
For example, https://{ap27.lightning.force.com}/lightning/page/home

In this URL {ap27.lightning.force.com} is dynamic and could vary.

Repositories with such links cannot be integrated with Whatfix.
