is it possible to have same names for my pacts only difference is one is provider and another is consumer?

No, names cannot be duplicates as they identify uniquely the application in the system. If the application is both a provider and a consumer, it is the same application and not two different ones

my app published event

KEY_GENERATED

from authService and I have a subscriber in userService that subscribe

KEY_GENERATED

what’s that got to do with naming of the services?

my app name is labeled as

auth

im going to trying naming consumer as

KEY_GENERATED_CONSUMER

and provider as

KEY_GENERATED_PROVIDER

then

I’m still unclear. Why are the app names not simply

authService

and

userService

?
