As a developer, when I go to the Graph Search Management page for an instance, I can create a developer instance. It shows the keys in a dialog. That dialog should have a field that displays the keys in a way that I can easily copy/paste into a PaaS CMS configuration file.

This is the URL of the page I'm referencing.
https://cg.optimizely.com/portal/ (my instance ID )/dev-account-management

This is a feature we have with FIND Search And Navigation on https://find.optimizely.com/MyServices/AddFreeIndex

The format should be json like :

"Optimizely": {
"ContentGraph": {
"GatewayAddress": "https://cg.optimizely.com",
"AppKey": "xxx",
"Secret": "yyy",
"SingleKey": "zzz",
}
}
