You can delete endpoints that are not used in message flow configurations from the Host or Partner page:
From your Anypoint Partner Manager Sandbox or Production environment, select the <host name> or Partners from the left navigation menu.
Search for the endpoint you want to delete by name, protocol, URL, or description.
From the Host page, you can search from within Endpoints: Receive from <partner name>, Endpoints: Targets at <partner name>.
From the Partner page you can search for an endpoint from within Endpoints: Receive from <partner name> or Endpoints: Send to <partner name>.
If you can’t remember what to search for, scan the list for any endpoints that don’t have a message flow associated with them.
Endpoints that are not associated with a message flow are indicated by a
0in the message flow column.
Hover over the endpoint name until you see the garbage can icon.
Select the trashcan icon and then click Delete.
