Unique name for the application creation

I can’t offer any solutions for this right now other than just handling 409 status codes in response while creating clients. I’ll let others to chime in if anyone has solved this by other means. I wouldn’t recommend polling GET /clients endpoint to get all existing clients list and checking for uniqueness. By doing that you would be using your management api rate limit quota and management api endpoints are not supposed to be use fo high frequency calls, just for CI/CD or general CRUD configurations stuff.
