Tyk Cloud: How to retrieve values/parameters?

I’ve created an API like this:
https://myname.cloud.tyk.io/productname/
Any request without paramters works well. The endpoint provides all items of productname.

Now I want to retrieve data for a specific item and my request is this:
https://myname.cloud.tyk.io/productname/itemA

I get a response, but it is just the basic response, as without “…/itemA”.

The same happens when I retrieve data for a specific item and date:
https://myname.cloud.tyk.io/productname/itemA/2017-11-27

I still get the basic response.

The endpoint has a RewriteRule. The endpoint expects:
https://www.myurl.com/API/itemA/2017-11-01

I have also tried to enable Context Variables, but this has no impact.

Is it possible to retrieve two values and how to do that with tyk Cloud?

It’s likely your rewrite isn’t firing

Direct calls at the endpoint works well. The three possible direct calls on the endpoint provide the desired data:
https://www.myurl.com/API/
https://www.myurl.com/API/itemA/
https://www.myurl.com/API/itemA/2017-11-01

I would like to use API-Gateway from tyk, but tyk is only retrieving the base url. When I make a call on
https://myname.cloud.tyk.io/productname/itemA, then I want that tyk retrieves data from https://www.myurl.com/API/itemA/, but I get only the data from base url.

How to pass the values correctly in tyk Cloud? When you say that my rewrite isn’t firing, then can give me advise how to do that with tyk? In tyk cloud, I’ve seen that there is a tab to rewrite url, but I don’t understand how to use it, because the docu is insufficient.

Have you added a URL rewrite? if so, what values have you used for the URL rewrite?
