@smhutch Does the portal you are making connections to have deleted URL mappings(I know it sounds dumb and obvious). I want to make sure you aren’t by accident using a hapikey to a dev portal or the wrong one. The example I posted above worked for my own portal when I tested it out before my last post. Since I have it working on my side I am a tad lost as to why we can’t replicate it on your end.
