Using Service API with Web API


I added Service API to my application in order to process some data manipulation, but after I did that, my Web API calls stopped working. This is a know issue as described here (, and after reading that I understand why Service API breaks it. What I don't understand and what doesn't seem to be explained there is how to get it to work again. Is there a way to get both of them to work together without changing the authentication works on Web API? That post mentions disabling something and contains a line of code relating to removing a MessageHandler, but it isn't clear to me what that is for.

Can someone explain this to me with a bit more info? (I'm not well versed in authentication techniques so maybe that explaination just went right over my head)

There is currently no workaround for the supression of cookie authentication when you install ServiceAPI. The obvious alternative is to install ServiceAPI on a separate site to avoid that impact.
