The API gateway used in dojot reroutes some of these endpoints so that they become uniform: all of them are accessible through the same port (default is TCP port 8000) and have the same naming scheme. Each component, though, might have something different in its configuration and API documentation. The following table shows which endpoint exposed by the API gateway is mapped to which component endpoint.

Kafka messages

These are the messages sent by components and their subjects. If you are developing a new internal component (such as a new IoT agent), see API - data-broker to check how to receive messages sent by other components in dojot.
