In MuleSoft you have the possibility to configure autodiscovery. The autodiscovery feature allows a mule runtime to be paired during deployment with the API Management portal. After you have paired the application you have the ability to enforce policies and have access to tracking information.
This feature is pretty well documented on how to configure autodiscovery but sometimes you can get in trouble configuring this feature. This can especially be true when you need to connect to the EU control plane instead of the default US management plane.
