Kafka producer and consumer within on sync execution

[Rams N <99...@gmail.com>]

Hi,
I've an usecase to respond to an API call to the client which should happen
in sync. But within the api execution, the system A need to publish a kafka
message to an different system B and which responds to another kafka topic.
The response must be consumed by A and should respond to the client as API
response.

So, here this problem has a async pub-sub model and also API handling,
which is a sync.

Any suggestions on implementing this highly appreciated.

thanks
Rams
