Calling Apigee X Integration (API trigger) from API Proxy

[esync33]

Hi, I created an Apigee X Integration (with API trigger + SendEmail), and I was able to test it successfully from within the Integration (Test button). Now I am trying to invoke it from my API Proxy (Type: Integration Target). I was trying to follow this 'Getting started' guide, but it doesn't seem accurate. Is there any other documentation/video that walks through this simple scenario?

I see that there's some inaccuracy wrt the testing step. The hostname should be the hostname you should use for your other Apigee proxies and not:

https://ORG_NAME-ENV_NAME.hybrid.e2e.apigeeks.net/PROXY_NAME"

 If there are any other place you got stuck when following the instructions, please let us know.
