Is there something built in to prevent a call to the CMS content api from the server side? I just get a

500 error

.

What are you trying to do?

nlapiRequestUrl

back to the CMS service address. I believe the address won't resolve correctly.

I am not sure what you call CMS Service Address but probably you are trying to call the service that get/post/update/delete an address, I have not done that in the server side. If you are on the service, I would call the specific method from the address model (if you are into a custom module). If not and you want to make a request to that service, you should check the network and see the full URL used to invoke it and pass the expected payload.

I have not done that before but take a look here:

checkout.environment.shortcache.ssp
