As @Jon2 has shown where to create OAuth Clients in Dynatrace. But what exactly OAuth are and the usecases where we can use OAuth.

OAuth clients in Dynatrace enable secure authentication and authorization for third-party applications or services, allowing them to access Dynatrace APIs without needing user credentials. The primary purposes of OAuth clients in Dynatrace are:

#) OAuth clients are used for securely accessing the Dynatrace API where you will get Bearer Token to authenticate the API.
#) OAuth clients allow developers (Dynatrace AppDevs here) to build custom apps using App Engine that interact with Dynatrace for solving custom usecases/solutions.
