Thanks for the quick response and I apologize for the delay. I was running into issues that I needed to replicate in a sandbox. I got the url in question working sending batch requests.
On my local sandbox it's working great. But in our production instance (hosted AWS ESB) the individual requests are now returning 404s.
We use custom domains. Does this feature work with custom domains? The default domain is also giving me problems.
Can you confirm: the batch aggregator is appending the
relative_url to its own API uri. e.g. A request for
"relative_url": "get" sends the request to
http://gateway.domain.com/httbintest/get. If so, then I'm guessing the issue is that the box itself doesn't have a dns entry for
gateway.domain.com. My fear is it's pulling the URI from something else - like the environment specific $HOSTNAME value.
