 There are scenarios where microservices must call each other. For this case, a helper class is implemented, which performs the necessary steps automatically. This class can be found at ```src/modules/security/token_manager.py```. The class is a singleton, so the ```getInstance()``` method gives access to the only available instance of ```TokenManager```, where the method ```getToken()``` can be used to retrieve a JWT token for internal requests. The roll of this user has regular User permissions.
 
-```TokenManager``` uses the credentials stored in ```regular_user_credentials```.json to authenticate at the rest-gateway and caches the returned token, such that multiple requests to ```getToken()``` return the same one, which reduces traffic.
