     - FIRST, You can only send ONE METHOD with a chain; you cannot send a PUT and POST method in the same call. But you can just default every other call to a SAFE call (ie GET) as long as client has AUTHORITY to the endpoint. SECOND, since it can only have one UNSAFE METHOD, you can only send ONE DATASET. We made it to be as simple as possible while encompassing the most commonly used calls thus simplifying the processing and the client call.
 - **Isn't it BAD to send form data with a GET request? I thought you could only send URI encoded data??**
     - Per W3C guidelines : 'A client SHOULD NOT generate content in a GET request unless it is made directly to an origin server that has previously indicated, in or out of band, that such a request has a purpose and will be adequately supported'. API Chaining(tm) is that direct connection with purpose. It provides the necessary backend checks and limits what can be sent.
+- **Passing a timestamp causes an error and no data is returned with a status 200??**
+    - If you are passing an Object, said object MUST be converted to a String. Json does not understand objects and everything is a String. make sure when writing your tests to do the conversion in the controller so that all variables are passed as Java.lang variables (ie String, Integer, etc)
