transitionType and contextData -- Why are they required in the queryString for website?

Joshua Krebs

I have noticed that almost all website url query strings contain transitionType and contextData. I have also noticed that when these aren't present, we get errors on the page like the following :

Sorry, there was an error on this page.Less info
A page redirect occurred because of one of the following query string issues: missing transitionType, bad transitionType, missing contextData

What are these parameters for, how do they get added, and are they actually necessary for all products?

The data within the `contextData` parameter is used for billing purposes; the fields eventually make their way to UDS when determining how to bill the customer. The data found within this payload are the folder correlation ID, the original context, and the source context. The WLN billing rules require some things to be billed differently depending on how the user accessed the content.

The `transitionType` is also used by UDS when determining the proper billing context to be used. When a user is doing things within their folders or within a search result, we might bill them differently than if the user accessed that content via a browse page or a find.
