How can I subscribe to an external api?

[Sayed Erfan Arefin]

I need to subscribe to an external api with web socket in order to receive messages from a topic to consume it in lagom. Later I will use the message to publish it to a different topic for internal usage. How can this be achieved?

This post of Knoldus explains it very well.

Basically, you need to add an entry on onManagedServices pointing to base URL of this external service and to create a trait to this service.
