TNEW New Order Interceptor

Question

Hi Gang - This is probably a relatively simple answer, but I'm just getting started developing some interceptor plugins. I have a functioning plugin that fires on an intercept of a POST to Txn/Orders that works great any time an order is created in the Tessitura client application or when I trigger it manually from the Web api client - but it seems that TNEW never creates a POST to Txn/Orders when a new order is created. 
 The help documentation for the POST to Txn/Orders reads This resource is currently only for interceptor plugin use. This is called any time a new order is saved via the API or from the client application. Only OrderId is provided in the request content.... And the documentation for Web/Cart/{sessionKey}/Checkout has a line that reads In order to facilitate the use of the interceptor capability, the checkout method now makes a POST call to Txn / Orders.By default this call does nothing unless a developer has added interceptor plug -in code to the exposure. 
 Am I doing it wrong? Does anyone know what verb/endpoint I can intercept any time a new order is created in TNEW? 
 
 Thanks,

It ended up being a slightly different issue with TNEW. I'm paraphrasing - but I guess certain parts of TNEW still use the SOAP API and then access the REST API from within a SOAP API call. The intercept still happens and the plugin fires - but the security context of the plugin gets a little messed up because it is called from a _TNSvc credential instead of your TNEW REST credential. You really can't "do stuff" in the plugin with the _TNSvc credential. Had to hard code in different credentials instead of being able to use input.UserName and input.UserGroup, etc as suggested in all the sample plugins.
