I am currently encountering several issues while working with the CPQ API, and the situation seems to have worsened over time.
Using the documented “Try it out” functionality, I can successfully retrieve a URL via the GetInteractiveURL endpoint. However, when I open this URL in an incognito browser, I receive the error: “CFG Query String was invalid.”
When calling the API via C#, I was—until recently—at least able to retrieve the same URL externally, although it resulted in the same error when opened. However, the issue has since become more severe: now I no longer even receive the expected URL response. Instead, the API returns only the OS login page as HTML.
I am observing similar behavior with other endpoints such as Exists, GetContent, and GetDynamicContent.
Is anyone here experienced with the CPQ API who might be able to help me identify what I could be missing or misconfiguring? My background is primarily in on-premise implementations of the CPQ API, so I would really appreciate any guidance, insights, or best practices when working in this context.
