Hi,

Can we use and "actor" symbol to represent an external entity in component diagram. For example, I have a third party "Credit Card Authorization" system which has exposed its own interface API, and the components in my system needs to interact with that third party system. What symbol can I use to represent that third party system in my component diagram ? Can I use the usual component symbol, or an actor symbol will suffice ?

Thanks,
Aju

An Actor and an External Entity are two different things. The UML symbol for an External Entity is a circle with a line under it.
